This is slightly off-topic but I hope not too much, and there is a reference to
struts here because I used to do this with struts1 taglibs!
I want to concatenate 2 vars into a string in EL but since one is a Long, EL
can't do it, and throws a NumberFormatException because it wants them both to be
Longs so it can do arithmetic addition instead.
<a href="${pc:url('/category/edit.html?category.id=' + category.id)}"
title="" class="icon">
<img src="${pc:url('/images/doc1.png')}" alt=""/>
</a>
pc:url is my taglib function that accepts a string parameter.
I see 3 possible solutions:
- put in a JSTL <url>
- create a new taglib function that takes parameters for URL parameters
- create a new taglib function that concatenates all types into strings
or is there a neat work-around I haven't thought of?
Lastly, is there anyone else taking this minimalist approach who would like to
open-source this stuff with me?
Thanks
Adam
