Re: Custom tag attribute runtime expression containing and delimited by quotes. Supported in Tomcat, but not other JSP containers. What is the standard?
Hmmm... We found in section JSP 2.6 (page 41) in the Core Syntax and Semantics chapter of the JSP 1.2 specification that this... mytags:tag value=%= hi! % / ...is expressly illegal. Should this be considered to be a bug in Jasper?

Hi, What happens with Tomcat 5.x? (To which JSP Spec 2.0, not 1.2, applies). The reason I ask is that while you can file away bugs against 4.x to your heart's content, it's not being actively developed and you shouldn't hold your breath waiting for a fix.

We won't be going to Tomcat 5 at work for a couple of months yet, but I'll try it out at home when I have some spare time.
