Hi all!

I have some problems with ComboboxCellEditors in a TableViewer. The
problems occurs when I try to change the value in the combo. When I do so,
Eclipse shows an error dialog which displays the message: "An error has
occurred. See error log for more details". When I try to close this one it
immediately pops up again and this behavior is repeated around 25 times.

The error log gives me the following information:

!ENTRY org.eclipse.ui.workbench 4 2 2007-01-28 11:27:55.000
!MESSAGE Problems occurred when invoking code from plug-in:

The strange thing with this problem is that I have debugged my code and it
behaves as expected so I wonder if this might be a bug?

My CellModifier that handles the mapping between the table and the model
is partly shown below:
public Object getValue(Object element, String property) {
IProjectRow row = (IProjectRow) element;
int index = getIndexOf(property);

switch(index) {
case(0): ..
int i = unitTypes.indexOf(row.getUnit());
return new Integer(i);
case(4): ..
default: return null;
}
}

Where case 0 is retrieves the current value of the model (which also is a
selectable item in the combobox). My modify code is given below:

public void modify(Object element, String property, Object value) {

...

switch(index) {
case(0):
String val = (String) unitTypes.get(((Integer)value).intValue());
default:
;
}

tableViewer.update(row, null);
}

Remember that I have debugged the code and I haven't found any bugs. It
behaves as expected. I'm developing a RCP application using Eclipse 3.2 on
Windows XP SP2. Is it my code that might be erronous or might it be an
Eclipse bug?

I suppose that the reason for your issue is because your getValue method
returns null.
The Combo value mustn't be null.
