jstl and tiles

[Simon Joseph Aquilina]

Hi,

Can I check the value of a tile:getAsString from a jstl tag. I have tried the following c:if however it is giving me a servlet exception

<c:if test="${<tile:getAsString name='banner'/>!=null}">
   <p>Doing Something</p>
</c:if>

The exception thrown is as follows:

[ServletException in:/WEB-INF/pages/template1.jsp] /WEB-INF/pages/template1.jsp(4,0) "${ != ''}" contains invalid expression(s): javax.servlet.jsp.el.ELException: Encountered "<", expected one of [, , , "true", "false", "null", "(", "-", "not", "!", "empty", ]' 

Basically I am using tiles to determine if a page should have a banner or not. I want that if in tiles-defs.xml the user does not set the tile element for the banner, then on the jsp page it does not try to load the image for it.

I do not know if there a simpler way to do this.

Thanks and Regards,

You cannot use a custom action as the attribute of another custom action, or as an EL expression.

So is there a way how I can solve this?

Like putting the value of the tile expression inside a varialble that can be handled inside the jstl tag?
