Upload form item in ListGrid not clickable

[Sytematic]

Hello,

I am using Power 2.4 (01-05-2011).

If I have a listgrid with a column with type="imageFile" specified in its .ds.xml file, and I have the gridinitialization like below, i cannot upload an image through it.

In edit mode, it shows the 'browse...' formitem, but when I click 'browse' it leaves edit mode. Is this a bug?

I really do not want to have a 'master-detail' paradigm on this part of my app, so I prefer to just be able to upload using the upload item in the listgrid.

My initializing code for the listgrid:

protected void init() {
        ListGrid grid = new ListGrid();
	grid.setWidth100();
	grid.setHeight100();
	grid.setAlternateRecordStyles(true);
	grid.setCellHeight(22);
	grid.setDataSource(dataSource);
	grid.setAutoFetchData(false);
	grid.setCanEdit(false); 
	grid.setModalEditing(true);
	grid.setShowFilterEditor(true);
	grid.setDoubleClickDelay(30);
	grid.setEditEvent(ListGridEditEvent.DOUBLECLICK);
	grid.setListEndEditAction(RowEndEditAction.DONE);
	grid.setCanRemoveRecords(true);
        grid.setAutoSaveEdits(true);
	grid.setShowRecordComponents(true);
	grid.setShowRecordComponentsByCell(true);
	grid.setRecordComponentHeight(22);

//...
}

Is there anyone with a solution?
