[TYPO3-team-templavoila] RFC: #12504: Bugfix: pagemodule drag'n'drop is broken when running on 4.3beta

[Tolleiv.Nietsch]

This is an SVN patch request.

Type: Bugfix

Bugtracker references:
http://bugs.typo3.org/view.php?id=12504

Branches:
trunk

Problem:
The Drag'n'Drop function within the pagemodule stopped working in TYPO4 
4.3 - this happens due to the fact that currently the sourcepointer of 
an element is used as ID within the markup. The "xml:id" specification 
of XHTML doesn't allow ":" to be part of id-strings. It seems that the 
latest version of prototype (shipping with 4.3) has problems with 
invalid IDs and therefore drag'n'drop won't work anymore.

Solution:
The provided patch fixes it with a "simple" id=>sourcePointer registry. 
This makes sure that the actual ID only contains valid characters and 
provides access to the sourcePointer values indirectly.

Additional informations:
Another option would be to change the delimiter for the sourcePointers 
to be a "-" (that's the only character which is really left) - but due 
to the fact that I think that a "-" can most likely be part of a 
fieldname I'd prefer to keep ":".

Cheers,
Tolleiv
