> We don't have the issue if we downgrade to struts 2.5.9
> The checkbox causing the error is the following :
> <s:checkbox??
> id="%\{j_prefixe_shared_mailbox+#smbEmail+j_prefixe_member+#emailMember}"??
> name="%\{j_prefixe_shared_mailbox+#smbEmail+j_prefixe_member+#emailMember}"??
> fieldValue="%\{#emailMember}"??
> value="false"/>??
> We saw the WW-5178 , but in our case the value attribute is defined.
> We set a breakpoint in the modelToBoolean() function where the exception is thrown (Expression.java). It seems that the parameters.nameValue used in the template (<#if parameters.nameValue?? && parameters.nameValue>) is a modelString (and not a boolean) which is equal to :
> _sharedmb_a-b@sc.d_member_j.l-d@e.com (this value is what we set in the name / id attributes of the checkbox)
