Subject Problem with ExpressionEvaluatorManager in a custom jstl tag
Date Tue, 10 Jun 2003 09:42:29 GMT
Hi

I've created a tag using rt expression without trouble.

I 've created the same tag using jstl : in doEndTag(), I call
ExpressionEvaluatorManager.evaluate with the right parameters, but running
it, i get (in a try catch):

2003-06-10 11:19:59,963 ERROR [org.jboss.web.localhost.Engine]

I can't debug it, the exception is not catched.

I'm using other standard jstl tags (c, html-el, etc....) without problem

What's happening there ?
