EL-error, what to do?

#1 01-29-2008, 11:57 AM

Hi, I noticed a fully EL-variable give warnings in IDEA. Maybe I'm doing something wrong, please look at the attached screenshot.

If this indeed is a IDEA-error:
-Do you have to add support for every variable of that kind manually?
-Do I report such "small" bugs in the JIRA?

It certainly isn't a big matter, but it's annoying, and I don't want to turn off the error marking, because It's working great in the other cases.

this might be relevant http://www.intellij.net/forums/threa...sageID=5202895

is your "t:dataList" a custom tag ?

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

Please, create JIRA request

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

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

if this isn't an IDEA isssue, this might be a good start

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 <variable> element in the tld like

<tag>
<name>myTag</name>
<tag-class>aClass</tag-class>
<variable>
<name-from-attribute>var</name-from-attribute>
</variable>
....
</tag>

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