Hi
I have a problem with a URL containing a parameter of the form
action_...=... The page does not load with this parameter. For an example
see the xwiki.org start page (
http://www.xwiki.org/xwiki/bin/view/Main/WebHome?action_xyz).
The parameter action_... seems to be used for something, but I couldn't
find anything on what exactly and on how I can work around that.
Unfortunately this URL is created by an external source (Facebook), so I
can't change it.
Can somebody point me in the right direction?
Thanks,
Edo

I've just grepped the whole source code and I've found this:
In ActionFilter.java:
...
if (parameter.startsWith(ACTION_PREFIX)) {
…
where:
/** The query property name prefix that indicates the target action. */
private static final String ACTION_PREFIX = "action_";
This code is in a Filter. FTR here's its javadoc:
* A filter that dispatches requests to the right action, depending on the button that was
pressed in the editing form.
* This is needed since the browser cannot send the form data to different URLs depending
on the button pressed, and an
* XHTML form has only one target URL. In previous versions of XWiki this was accomplished
using javascript code, with a
* fall-back on a pseudo-dispatcher inside the {@link PreviewAction}, which was on obvious
case of bad code design.
* </p>
* <p>
* The filter dispatches requests based on the presence of a request parameter starting
with <tt>action_</tt> followed
* by the name of the struts action that should actually process the request. For example,
the button that does
* <tt>Save and Continue</tt> looks like:
*
* <pre>
* <input type="submit"
name="action_saveandcontinue" value="..."/>
* </pre>
*
* As a result, when clicking the button, the request is not sent to the form's target
(<tt>preview</tt>), but is
* actually forwarded internally to
<tt>/bin/saveandcontinue/The/Document</tt>.
* </p>
Hope it helps,

Thank you Vincent
Since I was not sure if this comes from XWiki or somewhere below I forgot
the obvious solution - to search the source.
