Wes Wannemacher commented on WW-2206:
-------------------------------------
Looking at the tags in the dojo-plugin, it seems that EL will not work in
hardly any attributes. Is this on purpose? My patch only fixes the case I came
across, but should I go ahead and make another patch that allows EL in all of
the attributes? Also, it seems that OGNL would still work, so would it be
better to just patch the JSP page in the showcase to use OGNL, rather than
patching the tag to support EL?

> href="%{ajaxTest}" />
> The generated TLD file indicates that expressions should not be evaluated in
> the src attribute. I will attach a patch which would fix the issue.
