EL-error, what to do?

this might be relevant http://www.intellij.net/forums/thread.jspa?messageID=5202895

is your "t:dataList" a custom tag ?

It's Apache Tomahawk. So it's probably just missing information from their tld.

Do you have any pointers as to how I can modify the tld-file to provide this validation information?

Please, create JIRA request

But isn't this a problem with Tomahawk's tld?

if this isn't an IDEA isssue, this might be a good start
http://java.sun.com/j2ee/sdk_1.3/techdocs/api/javax/servlet/jsp/tagext/TagExtraInfo.html

You may specify valid TagExtraInfo class for the tag in question
While this specifies information about Java variables, IDEA's el
supports pick up this information (but e.g. variable defined via 'var'
attribute is not returned by any tag extra info)

Ok, I'm not sure I understand exactly what you mean here.

Am I correct if I understand it as this:
I can define a TagExtraInfo, and that will work, but usually this is implemented directly in IDEA?

when i had looked at this, i discovered another way for tld writers to do this.

using the element in the tld like myTag aClass var .... ]]>

But i didn't see this specified for the common taglibs IIRC

Yes, you are right, certain attribute name knowledge is built-in into IDEA.

This still defines java scripting variable but, indead, it is easier to
use :)

That variable-tag did it for me. Thanks to both of you for helpful information!
