[TYPO3-team-templavoila] FYI48: #13154: Deleting the last element from a section in an FCE crashes rendering

[Tolleiv.Nietsch]

This is an SVN patch request.

Type: Bugfix

Bugtracker references:
http://bugs.typo3.org/view.php?id=13154

Branches:
trunk templavoila_1-4

Problem:
A PHP warning is shown when _pi1 tries to render an empty section.

Solution:
The attached patch adds a check to prevent this error.

Additional information:
The XML data to reproduce it needs to look like:
   <field index="fieldname"><el index="el"></el></field>

This can be achieved by deleting all elements from a section. Just 
creating an element and leaving the section empty won't produce these 
problems.

I'm going to commit this in 48hrs if nobody has objections.

Cheers,
Tolleiv
