RE: Struts2 Checkboxlist
Hi Prasanth, AFAIK this tag is like this: It calls getBar method of your action or finds bar in value stack to find out what to display. Same for baz to find out which to be selected. Then it calls yourAction.setFoo to post selected items. i.e. it is up to you what you do with it in setFoo method. Normally you should clear baz and fill it with them again to update selected items. Thanks for using Struts!

It seems firstly ${placeholder} is evaluated to empty by Struts then '' is
evaluated to ' by MessageFormat.

I guess '$'{placeholder} or $'{placeholder}' or '$''{placeholder}' should work
:\ could you please report back the result for each one? And which Struts
version you test?
Thanks for using Struts!
Kind Regards.
