Well, I have been working with the brilliant cforms for a while, but
now I am trying to do someting that is very natural in XML, but seems
to be a serios problem in cforms, and that is quite simply a tree
structure
Trying to something like this is really uncomfortable.
<tree>
<treeNode>
<treeNodeName>I am a node</treeNodeName>
<treeNodeChildren>
<treeNode>
<treeNodeName>I am a node</treeNodeName>
<treeNodeChildren>
<treeNode>
<treeNodeName>I am a
node</treeNodeName>
<treeNodeChildren/>
</treeNode>
</treeNodeChildren>
</treeNode>
</treeNodeChildren>
</treeNode>
<treeNode>
<treeNodeName>I am a node</treeNodeName>
<treeNodeChildren/>
</treeNode>
</tree>
The natural thing would to define a definition like this:
<fd:form>
<fd:widgets>
<fd:new id="treeNode"/>
<fd:class id="treeNode">
<fd:widgets>
<fd:struct id="treeNodeChildren">
<fd:widgets>
<fd:new id="treeNode"/>
</fd:widgets>
</fd:struct>
<fd:field id="treeNodeName">
<fd:datatype base="string"/>
<fd:label>Tree Node
Name</fd:label>
</fd:field>
</fd:widgets>
</fd:class>
</fd:widgets>
</fd:form>
However directing a fd:new "treeNode" within the fd:class "treeNode",
creates a recursion error. I can naturally understand that the developer
wanted to hinder an tree structure being huge in memory for no reason.
Does any one know how to do this using cforms in a reasonable way.
Thank You
Chris Bentley
