IIRC this is an issue with spaces in parameter names; there have been a couple of threads about it on the struts-user mailing list.

I *believe* this has been fixed for future releases, but you'll probably want to check the list archives to make sure.

Hi David,
I am also same error, as OGNL is not able to recognize the "href " tags generated by display tag (EX. http:XXX/{Application}/YYY.action?d-49653-o=2&d-49653-s=3 )

And I am using Struts 2.1.8.1 & displaytag-1.2.jar , so hope this problem is not yet resolved.

Can anybody please suggest any work around for the same. I'll be really thakfull for that.

The trick is to modify the interceptor-ref in struts.xml for the "params" interceptor. I am excluding these params:

<param name="excludeParams">
   dojo\..*,^struts\..*,_.*,d-\d+?-[sop],^\d+(f?\d+)?$
 </param>
