Hi Daniel,
This is a known issue: http://www.canoo.com/jira/browse/UBA-7092.
The workaround is part of the issue, i.e., do the following after setting
the editor in your code:
column.setCellEditor(new ITableCellEditor() {
...
});
>>> table.upload();
>>> table.setDefaultEditor(StringBuffer.class, null);
Thanks and regards,
Janak

>Subject: [ULC-developer] Table edit problem with cell editor since 6.1
>
>
>
>Hello!
>
>Since ULC version 6.1 we have a special problem with clicks on a table, in
>particular editing the model. Please see the attached snipped to reproduce
>this behaviour. We implemented a checkbox celleditor and cellrenderer to
>show what we mean. If you fire up the table frame the first time, you have
>to click two times to change the value of the checkbox in column four.
>After you close the frame (not the application) and fire up the table
>again, you only have to click once. The code worked fine on ULC version
>6.04, where you only have to click once - even if it starts up the first
>time. If you run the attached snipped on the above mentioned versions you
>will see the difference. It seems the table has to focus first. Furthermore
>it isn´t possible to active the checkbox by keyboard.
>
>We already tried playing with "ClientContext" delivery mode options with no
>result. Btw. we had problems finding any documentation on the different
>event category constants from UlcEventCategories. It would be helpful, if
>you can update javadocs with the constants and there special meaning.
>
>We will be glad, if you have any hint or idea to solve this problem.
