It's a pity, especially for your very use case, but according to Howard, it's a design choice that brings simplicity, scaling possibility and other good things. So, you will have to change your recursion to an imperative loop. Fortunally, it's simple enought for a tree component (you can find an example here : http://svn.forge.objectweb.org/cgi-bin/viewcvs.cgi/interldap/interldap-wui-common/branches/wui-common/src/main/java/org/interldap/wui/t5lib/components/Tree.java?rev=389&view=markup Be carefull, it was for a very old version of T5 (perhaps 5.0.6 or so, and I believe a lot of thing are simplier now).

RE: Question about recursion in a component
You need to rewrite your recursive approach as a non-recursive one.
Take a look at the wiki for the Tree component:
http://wiki.apache.org/tapestry/Tapestry5TreeComponent?highlight=%28Tapestry
5%29
The code is a bit out of date because of changes to the handling of
Javascript, but you can see how something that is normally recursive is done
in Tapestry.

Question about recursion in a component
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.
onclick="javascript:UTILS_Change_Display('${item.identifier}')"/>
alt="${item.identifier}"/>
onClick="javascript:UTILS_Change_Color('name_${item.identifier}',
'black', '#ff');">
style="cursor:pointer">
${item.name}
name="${item.identifier}" style="display:none">
cellpadding="0">
Here I want implements the recursion (at
the momment I have another loop):
t:value="item">
style="padding-right:1mm">
border="0"/>
${item.name}
I'm new in tapestry and I don't know if is possible or not.
Thank you very much in advanced.

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.
onclick="javascript:UTILS_Change_Display('${item.identifier}')"/>
alt="${item.identifier}"/>
onClick="javascript:UTILS_Change_Color('name_${item.identifier}',
'black', '#ff');">
style="cursor:pointer">
${item.name}
name="${item.identifier}" style="display:none">
cellpadding="0">
Here I want implements the recursion (at the momment I have another loop):
t:value="item">
style="padding-right:1mm">
border="0"/>
${item.name}
I'm new in tapestry and I don't know if is possible or not.
Thank you very much in advanced.
