NSTableView setAction: raises an exception

[Stefan Urbanek]

Hi,

This:

    NSTableView *probesTable; /* table from .gorm file */
    ...
    [probesTable setAction:@selector(tableClicked:)]

will raise this exception:

    Uncaught exception NSInternalInconsistencyException, reason: attempt
    to set an action in an NSCell

But double-action works:

    [probesTable setDoubleAction:@selector(tableDoubleClicked:)]

I need  to handle both, single and double click.

What can be wrong? 

Stefan
