Hello,
I have a jsf, myfaces, facelets, tomahawk, displaytag and c:forEach
question. My apologies if you see this question in some other boards
relevant to this discussion.
This is the issue.
I load a list of customers.. I loop thru each of them using
c:forEach, ui:repeat, displaytag and t:dataTable. All of them behave
differently, if <c:if test is used inside the body tag.. All of them are
incorrect except for c:forEach (there may be a different problem with
display tag, as I can't get it to show up in this page.)
Below is the code for the page.. and the result follows it. The code is
self explanatory and the results show the discrepancy. I would
appreciate if someone could point out what I may be doing wrong, or if I
am not understanding how t:dataTable or ui:repeat works... Are there
issues with c:if evaluation at compile time versus runtime? Is there any
remedy to this?
Thanks
MRather
