Displaytag checkbox using struts2

Hello,

I have installed struts2.0.11 clean with maven2 and added the displaytag 1.2 dependency in pom.xml (and also the filters in web.xml).
Printing tables work perfectly well until I try to use the decorators which are used for posting form values with checkboxes as in this example at displaytag.sourceforge.net.
The error I receive when I'm running the homepage is the following:


The controller is returning a RowSetDynaClass, accounts to the jsp (PrintUsers.jsp) which looks like this:

I'd be happy to provide you with whatever information you need in order to help me out here.

Thanks in advance!

Please be sure to ask Struts questions in the Struts forum. I have moved this post there for you.

Readable JSP might help :p

Have you tried with a recent version of S2?

Hi David,

thanks for the quick reply!
(the jsp code should be fixed now)
I've also tried with Struts 2.1.6 but this gives me exactly the same error.

Ok, I solved it!
The displaytag decorator is looking for a DynaBean named "id" in the RowSetDynaBean table. (I'd guess to have something to sort the rows by)
So after I had added an id to the account table it stopped complaining, case closed!

Piz!
