Subject: <s:form> tag in Struts-Faces
I am trying to develop a web application using Struts, Tiles, and
JavaServer Faces, connected by the Struts-Faces integration
library. I
can't seem to make the <s:form> tag work.
The code I wrote looks like:
<s:form action="/search">
The /search action is configured in struts-config.xml to forward to a
search results tile.
The code renders like this:
<form id="navbar:_id19"
action="/WebInterface/faces/start.jsp;jsessionid=B61380A7B5F73
72ABE0CA4D8FF109123" method="post">
where start.jsp is the page the form is on. This happens with other
forms too; when the <s:form> tag is rendered, the action attribute is
directed back on the current page.
I read the following article, which proposed sort of a hack to solve
this problem:
--> http://www-106.ibm.com/developerworks/library/j-integrate/
except this was written last September for an older version of
Struts-Faces, and some of the code it tells you to change is
different
now. I couldn't get this to work.
How do I get around this problem? It seems like something
pretty basic,
so I apologize if this is something that's been well covered already,
but I couldn't find information about it anywhere.
