Subject Re: Using relative actions in html:form attributes...
Date Thu, 01 Aug 2002 21:37:04 GMT
Hmm, interesting...  I was under impression that Struts
enforces the fact that form element tags must be inside
html:form tags.  Well, after your suggestion, I tried putting
them inside the regular form tags, and it did not complain.
So, at least in this version of Struts (1.0.2) it seems
to work.  I also had to add "name" attribute to every single
element of the form, otherwise I was getting the
following exception:

javax.servlet.jsp.JspException: Cannot find bean org.apache.struts.taglib.html.BEAN in scope
         at org.apache.struts.util.RequestUtils.lookup(
         at org.apache.struts.taglib.html.BaseFieldTag.doStartTag(

which is understandable, since without that attribute and without
enclosing html:form, elements have no idea where to find their
values.  Well, at least now I have a workaround, albeit not a
very clean one, in my opinion.  I still don't understand why
not let html:form use relative actions, perhaps I'm missing
something here.  In any case, thanks, Troy - your input
is much appreciated!
