I am using databinding to bind a model to a tableviewer. When iam changing the input object i receive an "assertion failed: Getter called on disposed observable" message. 
This seems to be similar to 
http://www.eclipse.org/forums/index.php/t/6747/
and 
https://bugs.eclipse.org/bugs/show_bug.cgi?id=283428

I am able to fix this by changing the order of adding the Content- and LabelProvider in the generated Code (1. Labelprovider, 2. ContentProvider). But then the Designer is unable to parse the code with following stacktrace: 



Reproducible: Always

Steps to Reproduce:
1. Create a testclass with a list of subclasses
2. bind the list of subclasses to a tableview
3. dispose DataBindingContext
4. change testclass
5. initDataBindings() => error
