RE: T5: nested loops don't work (can't figure this one out)
Arghh. Thanks a lot! I missed that. I figured it couldn't be a Tapestry
thing.
I traced back why I thought that the resulting sublist had an element (while
in fact it didn't): apparently a sublist is nothing but a wrapper around the
source-list (which I didn't know_, which is why burried in the debug
parameters the sublist still shows to have an element. Anyhow,
Thanks again.

Subject: T5: nested loops don't work (can't figure this one out)
Hi,
I'm breaking my head on this one.
I have 2 nested loops where the value of the outer loop is used as the
source of the inner loop.
The problem is that getCurPhotoAsThumb() is never called (as noticed by
debugging) thus nothing is rendered.
I've made sure that getCurThumbSublist() has at least 1 element.
Anyone?
I've supplied the relative template and class-parts:
TEMPLATE
-
t:loop source=listOfThumbSubLists value=curThumbSublist
div id=${currentThumbContainerId} class=thumbcontainer
t:loop source=curThumbSublist value=curPhotoAsThumb
${curPhotoAsThumb.url}
/t:loop
/div
/t:loop
CLASS
---
private int maxListsize = 6;
private ListPhoto curThumbSublist;
private Photo curPhotoAsThumb;

}
public void setCurThumbSublist(ListPhoto curThumbSublist)

Re: T5: nested loops don't work (can't figure this one out)
That should work just fine. Nothing jumps out at me as being wrong.
In fact, I just tried a simplified test case and it worked fine:
public Object[][] getData() {
return new Object[][] {
{ fred, flintstone },
{ barney, rubble }
};
}
@Property
private Object[] column;
ul
t:loop source=data value=column
li
ROW:
ul
t:loop source=column value=var:temp
li${var:temp}/li
/t:loop
/ul
/li
/t:loop
/ul
Which rendered as:
ul
li
ROW:
ul
lifred/li
liflintstone/li
/ul
/li
li
ROW:
ul
libarney/li
lirubble/li
/ul
/li
/ul

Great catch. Simpler is always better.
