so, do you mean something like this would work?
<span jwcid="recursionBlock">
<ul>
<li><span jwcid="insertValue"/>
<span jwcid="renderRecursionBlock"/>
</li>
</ul>
</span>
where the renderRecursionBlock gets recursionBlock as the Block to be
rendered... the part i'm missing is where would i keep the stack for
the recursion? what i did so far to achieve recursion was just a simple
recursive call in a component, as below:
protected void renderComponent(IMarkupWriter writer, IRequestCycle
cycle) throws RequestCycleException {
this.renderNodes(writer, cycle, this.rootNode);
}
protected void renderNodes(IMarkupWriter writer, IRequestCycle cycle,
ITreeNode node) throws RequestCycleException {
this.depth++;
this.value = node;
this.renderCurrentNode(writer, cycle);
for (Iterator i=node.getChildren().iterator(); i.hasNext(); ) {
this.renderNodes( writer, cycle, (ITreeNode)i.next() );
}
this.depth--;
}
protected void renderCurrentNode(IMarkupWriter writer, IRequestCycle
cycle) throws RequestCycleException {
// use writer to render some html for the current node
(this.value)
}
but obviously this is not very flexible/maintainable, since i'm not
using a tapestry html template...
