          choices are generated from the document tree now. This brings
                the state storage of select boxes in HTML to live.

2007-09-09 Sascha L. Teichmann <[email protected]>

        * tools/formed/formed/plugins/web/semantic.py: Fixed problems with
          range checking of integers.

          wrong index in Document.indexOfcomponentByClassAndName.

        * tools/formed/formed/plugins/web/form_renderer.py: 'error' was
          written 'errot' in renderer for textareas.

        * tools/formed/formed/plugins/web/controllers.py: Some clean-ups.

2007-09-09 Sascha L. Teichmann <[email protected]>

        * tools/formed/formed/plugins/web/help.py: Added a 'hasHelp'

          tools/formed/formed/model/persistent.py: Add a getValue() method
                to dataset abstraction. This is a bit of a workaround to bring
                global access across pages for rule checking to work.

        * tools/formed/formed/model/data.py: Fixed: When setting a new expression
          the compiled version was not stored in the RuleLeaf.

        * tools/formed/formed/model/expr.py: shlex lexer does not like unicode.
          convert the expression string to ascii for compilation.

        * tools/formed/formed/plugins/web/semantic.py: Remove the 'box' because
          valid data is stored to the dataset immediately now. Fixed a bug 
                with integer handler.

        * tools/formed/formed/plugins/web/controllers.py: Removed the semantic 'box'
          stuff. When a submit is done extract the rules from the tree document
                that are effected by the modified variables and check them.

        * tools/formed/formed/plugins/web/renderer.py: Fixed exception handling
          when dealing with templates.

2007-09-06 Torsten Irlaender <[email protected]>
        * tools/formed/formed/plugins/web/renderer.py: Mainly tried to get the
          getFormData interface to work. Added two small semantic fixes, but
          did not manage to get it up. Need to exime this a little bit more

          tree traversals is a common task. To ease this a decorator function
                checkMode in union with sub classing ModeChecker can be used.
                To make it work simply subclass from ModeChecker and add the decorator
                to the methods that need mode tracking. Before you start the recursion

                own. This was silly code replication. Now there is an abstract
                base class 'FileDialogFilter' which implements the common
                behavior. The file exporters should subclass it.

        * tools/formed/formed/plugins/export/sql.py: Subclass the SQL
          exporters from the new base class. TODO: Subclass the HTML
                exporter too.

        * tools/formed/test-data/simple.xml: Modified to contain a rule.

        * tools/formed/formed/model/expr.py: Added. A simple RPN
          expression evaluator. To avoid the problem of eval()ing
                arbitrary python expressions I've decided to use a very
                basic and limited stack machine to support rule checking.

        * tools/formed/formed/model/data.py: Added a RuleLeaf.

        * tools/formed/formed/io/document.py: Added factories for rules.

        * tools/formed/formed/model/nodecomponents.py: Add a method

          to attribute table to report exceptions when setting a value
                from GUI. Useful to report compilation errors when setting
                expr of rule leafs.

        * tools/formed/formed/main.py: Added a method to track exceptions
          from the attribute table and pop up dialogs if they occur.
                Added a counter of rule modifications in tree. Useful if you
                want build cached data structures like rule sets and you want
                to know if they are still valid.

          to calculate the effective mode of an item.

        * tools/formed/formed/plugins/export/html.py: Use effective
          mode. TODO: the 'all' modus return false results sometimes.
                Cause: The modes are only cumulated over time. Removal is
                not done.

2007-08-24 Sascha L. Teichmann <[email protected]>

2007-08-23 Torsten Irlaender <[email protected]>

        * tools/formed/formed/plugins/names/filter.py: Added an
          pseudo SQL export filters. TODO: Move HTML and SQL filter

        * contrib/extract-xfa-fields_and_options.xsl: Added small xsl script 
          to extract fields and options in the XFA Data in teh PDF. This 
          script might me handy to indicate changes between the different 
          formular versions.
        
2007-08-23 Sascha L. Teichmann <[email protected]>

        Replace technical types with readable descriptions

2007-08-21 Sascha L. Teichmann <[email protected]>

        * tools/formed/formed/plugins/web/plugin.py: Fix a few smaller
          issues. 'action' looks for all widgets on a page now, goes
                through all passed parameters, tries to match them with the
                widgets of the page and put them into the semantic box.
                Afterwards a list of untouched page parameters are left
                which will be deleted from the semantic box.

        * tools/formed/formed/plugins/web/plugin.py: Simple test for
          listing all widgets in page.

          tools/formed/formed/plugins/web/renderer.py: Added a
          simple cookie based session management to the HTML
          renderer. This submit parameters are stored in the
          session now. This will ease testing the constraint
          tests which need to be written soon.
                
          BEWARE: The session management is _not_ made for production!
          Denial of service attacks are too easy, and the 
          cryptographical strength of the session id is doubtful.

2007-08-18      Sascha L. Teichmann <[email protected]>

        * tools/formed/formed/plugins/web/renderer.py: Escaping text 
          coming from the document tree now when inserting it into the

          selects their respective menu item.
                
        * tools/formed/formed/config.py: Contains the list of
          installed filters.

        * tools/formed/formed/main.py: Builds the Extra->Filters
          sub menu during gui initialization. The hard wired code
          for make unique and formular name/description -> name
          is removed because they are implemented as filters now.

        * tools/formed/formed/model/nodecomponents.py,
          tools/formed/formed/model/data.py: Removed the make
          unique and formular name/description -> name code.

        * tools/formed/formed/plugins/names,
          tools/formed/formed/plugins/names/__init__.py,
          tools/formed/formed/plugins/names/filter.py: Added. Contains

        * contrib/convert-formedtree2html.xsl: 
        Heading level depending on depth of group node. 
        In case of radio/choice/check only list of options.

2007-08-17      Torsten Irlaender <[email protected]>

        * contrib/convert-formedtree2html.xsl: Output is now generated with
          HTML doc-string and charset information in the meta-header. 

2007-08-17      Torsten Irlaender <[email protected]>

        * contrib/convert-formedtree2html.xsl: Added small script for 
          exporting the formed tree to html 

2007-08-17      Torsten Irlaender <[email protected]>

        * tools/formed/model/nodecomponents.py: Added function to rename 
          the set the name of the node to the formularname. The formularname
          gets shorten to <=64 by removing vowels and is stored lowercase.
          If the name is not unique and additional id value is appended.
        
        * tools/formed/formed/model/data.py: Overwritten renaming-function for
          bool-leafs

        * tools/formed/formed/model/data.py: SwitchNodes can add
          their modes to a given set now.

        * tools/formed/formed/plugins/plugin.py: Simplified
          the plug-in interface. Only the reference to the
                global configuration is passed at setup time.

        * tools/formed/formed/plugins/web/plugin.py: Adjusted
          to new plug-in setup. The traveral mode is now taken
                from the global configuration each time a rendering
                is triggered. The FORMED parameter is now named
                'doc.mode' instead of 'web.mode'. The parameter
                is not needed any more because it can be configured
                at runtime.

        * tools/formed/formed/main.py: Adjusted to new plugin
          setup. Added a new menu item Extra->Select Mode...
                to select the traversal mode. It is stored in the

          tools/formed/formed/config.py: Added a 'web.mode' parameter
                to FORMED environment variable.
                e.g. 'FORMED=web.mode:modeX' sets the mode 'modeX'.
                Defaults to 'default'.

        * tools/formed/test-data/simple.xml: Added test for switch.

2007-08-14      Sascha L. Teichmann <[email protected]>

        * tools/formed/formed/model/nodecomponents.py: Added an
          attribute 'formularname' to base class of node components.

2007-08-13      Sascha L. Teichmann <[email protected]>

        * tools/formed/formed/io/document.py,
          tools/formed/formed/model/data.py,
          tools/formed/formed/model/nodecomponents.py: Added an item
                to model external item lists.

        * tools/formed/formed/plugins/web/renderer.py: Render new item
          list.
        * tools/formed/formed/main.py: Added a forgotten 'self.'

        * contrib/extract-xfa-items.sh: Modified to generate
          documents to be loadable from new item lists

2007-08-13      Sascha L. Teichmann <[email protected]>

        * tools/formed/formed/main.py: Fixed typo

2007-08-13      Sascha L. Teichmann <[email protected]>

        * contrib/extract-xfa-items.sh: New. Can be used to extract longer
          choice item lists for a given field from XFA files. e.g. with
                './contrib/extract-xfa-items.sh Muttersprache alles.xml'

2007-08-12      Sascha L. Teichmann <[email protected]>

        * tools/formed/formed/model/data.py,
          tools/formed/formed/plugins/web/renderer.py,
                tools/formed/formed/io/document.py: Changed the structure
                of choice constructs. The idea to hold the different items
                of a particular choice in a semicolon separated list was bad.
                Now choices are groups and  the option items are modelled as 
                embedded bools. (mainly Torsten Irländer's idea). 

                WARNING: this makes old document files containing choices incompatible!!!
                Use the following XSLT to reestablish compatibility.
