Re: Resource Bundle Problem (sometimes)

I solved the problem!!! Because the tag was used inside another tag (that
extends LoopTagSupport) this caused the expression (or rather the setter
method) to resolve to spaces for the very first iteration of the loop. As a
result the tag was trying to look up empty spaces in the resource bundle and
failed. I now trim and test for this in the tag so it just prints an empty
space when that happens and then all the other iterations worked
successfully.

Quite a stupid mistake that took a long time to resolve... Thanks for the
input and help!
