That was the obvious ;)
Hi list,
I have a really weird bug which is quite annoying and I don't find any
solution to it :
I want to edit a page in inline mode. I have a form to select the page
to edit with a button. I use the $xwiki.getURL() method to get the right
URL. When i select my page and click on the edit button, I have an
invalid URL error and i am deconnected. What is weird is that if I
reconnect and actualize the page I can access it. The second weird thing
is that I use exactly the same method to edit other pages form other
forms in the same first page and I do not have the problem. I am quite
lost with this issue. I tried to recreate the URL as a string but I have
the same problem.
I am thinking maybe this is a known bug in xwiki. If not maybe i am
missing something somewhere. Please open my eyes on the obvious i am
missing in my code :
<FORM method=POST action="">
<input type="hidden" name="backlog"
value="${backlogId}" />
<input type="hidden" name="webname" value="Project"
/>
<input type="hidden" name="name" value="backlog"
/>
<input type="hidden" name="domain"
value="${domainId}" />
<input type="hidden" name="cut" value="${cut}"
/>
Select topic : <SELECT name="topic">
#foreach ($item in $topiclist)
#set
($topic=$xwiki.getDocument(${item}).getObject("XWiki.TopicClass"))
<OPTION
VALUE="${topic.id}">$topic.get("name")</OPTION>
#end
</SELECT>
<input type="button" value="Select"
onclick='{this.form.action="../../view/" + this.form.webname.value +
"/"
+ this.form.name.value + "?backlog=" + this.form.backlog.value +
"&domain=" + this.form.domain.value + "&topic=" +
this.form.topic.value.substring(this.form.topic.value.lastIndexOf("${separator}")+1)
+ "&cut=" + this.form.cut.value; this.form.submit(); }'/>
<input type="button" value="Edit"
onclick='{url="Project."+this.form.topic.value;
this.form.action="${xwiki.getURL(url, "inline")}";
this.form.submit(); }' />
Classic mix between serverside and clientside scripting.
${xwiki.getURL...} is executed on the server, before
the page is
displayed in the browser. url is a javascript variable, created long
after the velocity engine tried to generate the URL. I'm surprised you
didn't get a stack trace instead of the panel.
Still, this doesn't explain why you get disconnected, this should not
happen.
A lot of strange things are happening with this issue. I used this
method because the previous one was not working.
Try this:
<input type="button" value="Edit"
onclick='this.form.action="${xwiki.getURL("Project.__topic__",
"inline")}".replace("__topic__", this.form.topic.value);
this.form.submit();' />
This does not work, nothing happens, I stay on the same page and i am
still connected. Strange.
I tried also with :
<input type="button" value="Edit"
onclick='{this.form.action="../../inline/" + this.form.webname.value +
"/" + this.form.topic.value; this.form.submit(); }' />
and
<input type="button" value="Edit"
onclick='{this.form.action="../../inline/Project/" +
this.form.topic.value; this.form.submit(); }' />
I am then disconnected and still have my invalid url (Strange though
because this method gave me a good url in almost the same form on the
same page (instead of topic, it is domain ;)). (Note that if i validate
the invalid url (that is in my browser address bar), i go to the page i
wanted to reach and i am connected, refreshing does not work).
This uses $xwiki.getURL to obtain a valid URL
template, which uses a
placeholder (__topic__) instead of the real topic name, which in the
generated HTML appears as a string like
"/xwiki/bin/inline/Project/__topic__", and javascript replaces this
placeholder with the real value taken from the form
Thanks for this explanation,
clearer for me now ;).
Thanks for your time.
Jean
