Hi Mathias,
If you simply need to remove the references from the BasicSSCell's
display, you can do:
// save reference list
DataReferenceImpl[] refs = cell.getReferences();
// temporarily remove references
DisplayImpl display = cell.getDisplay();
display.removeAllReferences();
// do some stuff
......
// re-add references
for (int i=0; i<refs.length; i++) display.addReference(refs[i]);
Alternatively, if you really need to remove the references from the
BasicSSCell itself, you could try doing getData() on each of the
references first, then doing setData() later. If that causes problems,
let me know and I'll look into the issue further.
