Written actionhandler but can't set value I have code that writes out the following when used as a tag <sj4j:updateVariable name="destination" trueValue="home.jsf" falseValue="task.jsf?id='#{nid}'" condition="#{nid == '0'}" /> nameValue = destination ( String.class ) trueValue = home.jsf (String.class) falseValue = task.jsf?id='580' (..) conditionValue = false (...) NOW, I then do a if( conditionValue.toString().equals("true") ) this.nameExpression.setValue(context, trueValue.toString() ); else this.nameExpression.setValue(context, falseValue.toString() ); in my tag action listener. I get the following error when the tag is executed. Error updating variable: An exception of type "javax.el.PropertyNotWriteableException" was thrown ...name="destination: Illegal Syntax for Set Operation. Question is how to set the variable destination in the action listener? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4186080#...
