Why is setTimeout() required when calling SelectTextsInColumn() ?

[pvintona8]

Can anybody think why I would need to wait in order for the SelectTextsInColumn() function to work?

For example, this does NOT work:

   _this.Data.SelectTextsInColumn(0, false, 'my selection');

But when I wait 1ms, it works perfectly:

   setTimeout( function() { _this.Data.SelectTextsInColumn(0, false, 'my selection'); },1);

As you can see in this example, all of the arguments for SelectTextsInColumn() are hard-coded, so I don't think my code has to wait for some other asynchronous operation to complete.

Has anybody else seen this behavior?

In case it helps, I am using javascript inside of an extension.

Thanks in advance for your help!
