Hi,

When using the Nebula TableCombo, we recognized that a selection listener added to the TableComboViewer always receives a selection event for the first row of the table whenever the drop down box gets opened (e.g. the user clicks on the arrow button next to the combo box) .

Is this an intended behavior or a bug?
It is reproducible by simply running one of the examples of the official sample snippets in
https://www.eclipse.org/nebula/snippets.php#TableCombo and setting a breakpoint into the "selectionChanged()" method of the SelectionListener.

This behavior of the TableCombo produces undesired side effects when the table viewer is bound to an external model that reacts to selections in the table (as it is in our RCP application) as one gets selection change events although the user did not select anything.

Hi Matthias,

Yes this sounds like a bug to me. Initially the first element is not selected so it should not fire a selection event on that element. If you file a bug and supply a patch through Gerrit I will make sure that it gets in.

Best regards,

Hi Wim,

When I click on the link you posted (https://wiki.eclipse.org/Nebula/New_Contributions), my Firefox Browser on CentOS displays the following error page:

"MediaWiki 1.26 internal error
Installing some external dependencies (e.g. via composer) is required. "

A temporary hiccup, i'm sure.
