TableViewer display problem in Master/Detail block [message #461052]

Hi,

I write master/detail block in my plugin.
I want display tableviewer in detail block when item selected in
masterblock.

table create code in IDetailsPage#createContents

(in createContents)

Table table = toolkit.createTable(client, SWT.V_SCROLL);
gld = new GridData(GridData.FILL_BOTH);
gld.widthHint = 20;
gld.heightHint = 100;
table.setLayoutData(gld);

TableViewer viewer = new TableViewer(table, SWT.BORDER);
viewer.setItemCount(16);
viewer.setContentProvider(new SecurityTableContentProvider());
viewer.setLabelProvider(new SecurityTableLabelProvider());

but in runtime, exception occurred when I selected some item in master
block. I traced exception point what is viewer.setLabelProvider
BusyIndicator exception.
I think it may trying draw tableviewer when detail block is not ready.

Is there any other strategy?

Thanks in advance.

Jung.

Ok. This means that JFace tries to disassociate an element item relation
where on item exists in the viewer. It has nothing to do with drawing!
For a possible reason please see below.

The next line is not right! You are not supposed to set the item-count
for tables who are non-virtual!

>>> viewer.setItemCount(16);
>>> viewer.setContentProvider(new SecurityTableContentProvider());
>>> viewer.setLabelProvider(new SecurityTableLabelProvider());
>>>

One more thing could you please somehow change the encoding in your
mails to e.g. Unicode when posting, currently you are using EUC-KR?
