[TYPO3-Solr] no cores after update

[Tim Wendisch]

Hi there,
since the last update it is not longer possible for me to "see" my two 
cores in the BE-Module. The same Problem can be seen in the scheduler.

The values of the select field for the core choice is filled, but it is 
not given out.

As example:

<select 
onchange="jumpToUrl('mod.php?&amp;id=0&amp;M=tools_txsolrMAdmin&amp;SET[function]='+this.options[this.selectedIndex].value,this);" 
name="SET[function]">
		<option selected="selected" value="7|0"></option>
		<option value="7|1"></option>
</select>
