I was now able to edit the XML file in a very painful way... however in 
the part of the XML file decribing field 773 $t I found some characters 
like this:

<ss:Data ss:Type="Number">-6</ss:Data>

and I replaced them by

<ss:Data ss:Type="Number">0</ss:Data>

Now the behaviour while editing of the framework is still as described 
above (tab "Advanced constraints" won't open). But when actually using 
the framework during catalogueing, the MARC field 773 is there with both 
configured subfields $t and $w.

I guess this shouldn't be like this. Is this a bug?

Best wishes: Michael
