Hi !
I use a model class in my gef editor which wrapps a SWT.LIST
I have a problem adding items to this list from the propertysheet (I add
them from a TextPropertyDescriptor) : the items are added OK to the
SWT.LIST, the changes are reflected in the view, but the changes are not
reflected in the property descriptor that reflects the SWT.LIST items.
This property descriptor is a simple ComboBoxPropertyDescriptor which
takes as parameter the list returned by SWT.LIST#getItems(). I
initialize it whith an empty array, and then I change this array to
SWT.LIST#getItems() when items are added.
It seems to me that the ComboBox is ReadOnly so the changes are not
reflected, instead of TextPropertyDescriptor that reflects changes in
the model.
Am I right ?
What is the solution for a ComboBoxPropertyDescriptor, as I don't want
to make it "not READ_ONLY" ?
TIA

BTW, I think out propertysheetentry refreshes on all command stack events.

And, do you write your own ComboBoxPropertyDescriptor instread?
Otherwise, your modification to the array parameter will not reflect into
the combox of coz...

Yes, I wrote my own combobox actually, that reflects changes in the
array and as two buttons for other actions.
I'll try to restart this piece of code from the beginning, I certainly
missed something.
