Hi,
I have an expression that I want to get evaluated in a tag attribute. The
expression also contains a ${NODE.id} syntax which I want to escape.
The expression appears below. If I type this directly in the JSP page, it works
fine. However if I have it as an attribute for a custom tag, it throws the
exception shown below. NOTE : This works in 6.0.18 however when I changed the
servlet container to 6.0.20 with no change to the tag or jsp code, that's when
I started seeing this problem.
${jsObject}.expandHandler(${'${NODE.id}'},${'${NODE.treeNodeTypeIndex}'})
Exception Thrown
SEVERE: Servlet.service() for servlet jsp threw exception
