Struts2 s:if test for non-null value

Question

I am wanting to test for a non-null value using a struts2 tag. This works if I use the following:

..stuff..&l         


        

Answer 1

Using <s:if test="whatsoever the whatsoever is an OGNL expression that should evaluate to Boolean value if you want the tag is working right. If your field is of boolean type it's ok, in other case it's just doesn't work.

Also, in the documentation page for the if tag the type is defined as Boolean, so it's not primitive boolean but the value could be primitive boolean. So, be careful when using different types when evaluating the test case.
