Menus are inherently recursive.
In order to generate ours, I need to generate a series of UL and LI tags with
class="current" on the menu for the current page, and class="currentAncestor"
for the ancestors of the current page.
Example:
<UL>
<LI class="currrentAncestor"> <a t:type="pagelink" page="Index">Top
Level</A>
<UL>
<LI class="currrentAncestor"> <a t:type="pagelink"
page="Second">Second Level</A>
<UL>
<LI class="currrent"> <a
t:type="pagelink" page="Third">Current Level</A></LI>
</UL>
</LI>
</UL>
</LI>
</UL>
To avoid problems with Tapestry and recursion, I figured out I could setup
things this way, if the currentMenu has a list of its ancestors:
<t:loop source="currentMenu.ancestors" value="displayMenu">
<UL>
<LI class="currentAncestor"> <a type="pagelink"
page="displayMenu.page">${displayMenu.title}</A>
</t:loop>
<LI class="currrent"> <a t:type="pagelink" page="Third">Current
Level</A></LI>UL> <LI class="current"> <a type-
<t:loop source="currentMenu.ancestors" value="displayMenu">
</LI>
</UL>
</t:loop>
Problem is that's illegal XML above because I'm looping over open tags, and
then below I'm looping over close tags.
Is there any clever way around this besides looping over everything and then
using a delegate to insert the current menu at the bottom?
