inmethod datagrid with a DropDownChoice cell
I'm working with the inmethod datagrid. The grid is editable, and I have it
working just as the examples show, with a couple of cells that contain text.
As in the examples, clicking on a row changes some cells into TextField
components that can be edited.
Now I would like to create a cell that displays text, but when the row is
clicked the cell turns into a DropDownChoice component. I've tried to mimic
the EditablePropertyColumn and the TextFieldPanel with my own
EditableDropDownPropertyColumn and a DropDownPanel. These render fine and
let me select from the dropdown, but things go wrong when I press the submit
icon. I get an exception: "Attempt to set model object on null model of
component"
If/When I have time I will make a quickstart, but If anyone already has this
kind of thing working I would appreciate very much seeing the code.

Hi
Have either of you solved this issue?
You need to add the model to the new DropDownChoice
Solution:
public DropDownPanel(String id, final IModel model, IModel rowModel,
AbstractColumn column, final List data, final ChoiceRenderer renderer) {
super(id, column, rowModel);
DropDownChoice ddc = new DropDownChoice("dropdown",model, data, renderer)
{
Hope this helps.

Hello Will!
Have you solved this problem? I also need to have a data grid component with
dropdown column and can not find any examples. Thanks in advance!

I have come up with a quickstart project that shows my problem with creating
an EditableDropDownPropertyColumn for the inmethod datagrid. I'm sure I'm
not understanding something fundamental. The classes in the
edu.umich.med.irs.column package are my attempts.
If anyone has time to look at this I'd certainly appreciate it. Thanks.
