Problem with removeRows command in Simple table model

dvora lopez
Hi,

I'm working with Simple table model.  I have a delete button.  When the user presses delete, I want to remove the row selected from the model.
My command for this is:

tableModel.removeRows(index_of_row_selected,1);

I keep getting messages like this one:
this.__rowArr out of bounds: 11 (0..11)
where the 11 is the number of rows in the table.

index_of_row_selected is less than the number of rows in the table.

Anybody have any suggestions?
TIA.

Dvora Lopez

Hi Debora,

so in other words tableModel.getData().length is greater than index_of_row_selected?

index_of_row_selected is positive?

Tristan

Re: Problem with removeRows command in Simple table model

dvora lopez
Hi,

I managed a work-around today.  I finally realized that the row was being removed from the model, even though the exception was being raised.  So, I put the removeRows command in a try-catch and ignore the exception.  I don't like doing this - because it could cause other problems, but that's my solution for now.

Regards,
Dvora

Re: Problem with removeRows command in Simple table model

Dvora,

could it be that you have e selection callback handler in place that somehow
is called when the row is removed (and thus the selection disappears or
changes)? At least if you removed the last row of the table that would most
likely create a problem.

I remember vaguely to have had a similiar problem and had either disabled
the selection handler temporarily or changed something else in my code
(sorry to not be able to be more specific). Another thing I remember is that
I had a for-loop once inside which I removed rows. This obviously fails if
you iterate through the for-loop in a forward direction (increasing index),
as the length after removing a row is smaller than when the for-loop
started. If you run the for-loop backwards (from i=length-1 to 0) then this
problem does not occur.

Just some thoughts, I doubt that you are running into a Qooxdoo-bug, but
rather some not obvious problem in your code.

Cheers,
Fritz

Re: Problem with removeRows command in Simple table model

dvora lopez
Thanks for the reply.
I'm not even sure what a selection callback handler is - so I don't think I use one.  I just have a listener on the button for Delete.  But I'll look into that.

I always get the exception, even if it's not the last row being deleted.
My deletes are in fact in a loop, but I knew to iterate backwards.  Also, I get the exception even if I'm deleting only one row.

If you remember what problem you had - I'd really appreciate any hints.  Yes, I assume it's a code problem of mine.  Just can't figure it out yet.  If it helps to know - I'll add one more bit of information.  It took a while to realize that the row was being removed (despite the exception), because it only displayed properly (as removed) when I clicked on another row.  I took care of that programatically by adding a resetSelection command.  

Thanks again for trying to help.

Regards,
Dvora
