Hi Daniel,
Since ULC 6.1/6.1.1, the default model update event delivery mode for
ULCTable has changed to Deferred.
To achieve the desired behavior kindly add the following statements to your
code:
DummyTableModel model = new DummyTableModel();
table.setModel(model);
// Set the model update event delivery mode to synchronous
ClientContext.setModelUpdateMode(model,
UlcEventConstants.SYNCHRONOUS_MODE);
We have created an issue about documentation of the default model update
event delivery mode: https://www.canoo.com/jira/browse/UBA-7069.
Thanks and regards,
Janak

>
>Hello!
>
>We encountered a problem using checkboxes as cell editor/renderer. For
>unknown reason, checking the boxes doesn't work so well since the newest
>ULC version (6.1/6.1.1). We have several checkboxes in a table, to set
>options to different entries. The first column works like a radio button,
>where only one tableentry may have that option checked.
>
>May be the attached snipped will help you to show the problem. You have to
>play with it and try to uncheck the only checkbox of the first column.
>After the alert window is shown, the checkboxs' de-/selection doesn't
>work(!) so fine any longer. It seems, the 'fireTableDataChanged()' doesn't
>make his job because of a focus problem.

>Thank you and best regards,
