Hallo everybody.
My question is about how could I implement a recursion in tapestry 5?
exactly in a tree component. I have a collection of nodes with a Node
father and a Collection children, then in the tml I have a loop and
check if the actual node is father or not, but I want execute again the
same control for each children.
<t:loop t:source="source" t:value="item">
<t:if t:test="father">
<tr>
<td width="1%" valign="top" style="cursor:pointer">
<img src="images/plus.gif" border="0"
onclick="javascript:UTILS_Change_Display('${item.identifier}')"/>
</td>
<td width="1%" valign="top">
<img src="images/folder.gif" border="0"
alt="${item.identifier}"/>
</td>
<td width="1%" nowrap="true" valign="top"
onClick="javascript:UTILS_Change_Color('name_${item.identifier}',
'black', '#0000ff');">
<span id="name_${item.identifier}"
style="cursor:pointer">
${item.name}
</span>
</td>
<td width="*" valign="top">
<div id="${item.identifier}"
name="${item.identifier}" style="display:none">
<table border="0" cellspacing="0"
cellpadding="0">
Here I want implements the recursion (at the momment I have another loop):
<t:loop t:source="item.children"
t:value="item">
<tr>
<td width="1%">
</td>
<td width="1%" valign="top"
style="padding-right:1mm">
<img src="images/folder.gif"
border="0"/>
</td>
<td valign="top">
${item.name}
</td>
</tr>
</t:loop>
</table>
</div>
 
</td>
</tr>
</t:if>
</t:loop>
I'm new in tapestry and I don't know if is possible or not.
Thank you very much in advanced.
