Hi all,
I'm still coming up the learning curve on Struts2, and I've come
across something I can't explain. Hopefully you guys out there can help
me understand this. I have a request parameter "status" set to
"invalid" which I'd like to access from within a JSP. If I use the
following line:
<s:property value="#parameters.status"/>
I see "invalid" written to the HTML, which is what I expect.
However, if I try to use that in an expression, like this:
<s:if test='#parameters.status == "invalid"'>
this always evaluates to false. Similarly, this:
<s:property value="#parameters.status == 'invalid'"/>
prints out "false" to the HTML output. However, if I do the following:
<s:set var="foo">bar</s:set>
<s:property value="#foo == 'bar'"/>
that prints out "true" to the HTML output. Yet this:
<s:set var="status" value="#parameters.status"/>
<s:property value="#status == 'invalid'"/>
prints out "false" to the HTML output.
Can someone help me understand this behaviour please? Any ideas on
how to compare a request parameter to a string literal? Thanks,
Russ
