[PATCH] correct position of help popup for tab styling
------------------------------------------------------
Key: COCOON-1711
URL: http://issues.apache.org/jira/browse/COCOON-1711
Project: Cocoon
Type: Bug
Components: Blocks: Forms
Versions: 2.1.9-dev (current SVN)
Reporter: Werner Masik
Priority: Minor
Attachments: forms-advanced-field-styling.xsl.diff
Help popups appear in the wrong position when the tab styling is used.
Usually it pops up below the div that contains the tabbed form, which means
that the popup is often outside of the visible viewing area.
Looks like the bug exists since the stylesheets of 2.1.7 and dev branch were
merged.
The problem is that the function forms_createPopupWindow does not get called
when
the page is loaded into the browser. In current 2.1.X branch the function gets
called
directly from the <a href=" ...
<a
onclick="forms_createPopupWindow('email:help').showPopup('email:help:a');return
false;" href="#" name="email:help:a" id="email:help:a"><img alt="helppopup"
src="resources/forms/img/help.gif"></a>
So the function is executed when then link to the popup is clicked.
In 2.1.7 it was called like this:
<script type="text/javascript">
var helpWinN1003B = forms_createPopupWindow('helpN1003B');
</script>
<a onclick="helpWinN1003B.showPopup('N1003B');return false;" href="#"
name="N1003B" id="N1003B"><img alt="helppopup" src="/images/help.gif"></a>
Here the popup window was created at the first display of the browser page.
Actually when in tab-styling the whole popup-tree was just copied right below
the body-tag because of the positioning issues. This was done
with the forms_moveInBody function which was called in the onload handler of
the forms.
Therefore 2 possible solutions exist:
- revert the code to the old version, to register the handler before the onload
is executed
- alter forms-advanced-field-styling.xsl so the divs for the popups are all
created as a child of the body tag
The patch I'm submitting takes the second aproach. All it does is create the
divs where they should be
from the beginning (below body). This is done by introducing a mode called
'forms-help', to make the fi:help
tags get processed twice. In the first run the divs are created and in the
second run links for the popups
are created just behind the field (as usual). Moving the divs with javascript
therefore becomes obsolete. I think
that registering the onloadHanlder to call forms_moveInBody can be removed. But
I was not sure if
it is needed for something else, so I kept it.
I'm not a XSLT expert. There might be a better way to process the help popups.
Feel free
to make corrections. I also have no experience with ajax. I tested it with ajax
activated
and it worked. But I'm not sure if my test was using ajax the right way.
