exception.

styleClass="FORM" >

<layout:collectionItem title="SIGLE1" property="SIGLE1" width="150"/>

<layout:collectionItem title="SIGLE2" property="SIGLE2" width="150"/>

</layout:collection>

Just take a close look at the stack trace and read it from buttom up, and see
where the code fails...Usually it is something like:
NullPointerException
com.blablah.myAction (myAction:30)

which means the nullpointerexception happened at line 30 of "myAction" or
whatever class you are calling..
