Re: Struts2 Dynamic Checkboxes

[Torsten Römer <to...@luniks.net>]

Ah, I am such a dingbat... the beans in my list contained a property
with the same name as I used for the Collection property in the backing
bean. So when the tag was checking if the option was there or not it was
looking at some boolean property of that bean instead into the Collection.

Not before I downloaded the Struts2 source and debugged the
ListUIBean.compare() method I realized that ;-)

So this answers my question, and I am happy to say that my dynamic
checkboxes now work perfectly!
