Yes, it is returning the right path.

RB>  Try something like
RB> <html:hidden property="requestedPage"><c:out

I already tried this, it does not work. Basically, it should be the
same as

  <html:hidden property="requestedPage">
    ${pageContext.request.servletPath}
  </html:hidden>
  
or

  <html:hidden property="requestedPage" value="${pageContext.request.servletPath}"/>

which are both not working. Is this some stutsbug? Why is the
html:hidden tag marked in the tld file with a rtexpressions=false?

Regards,
Arne

Re[3]: EL Expression in html:hidden tag

[Arne Brutschy <ma...@studserv.uni-leipzig.de>]

Hello,

I got it, a simple

  <input type="hidden" name="requestedPage" value="${pageContext.request.servletPath}">

did the trick. I guess I shouldn't try to use struts tags too hard...

Thanks,
Arne
