onDataChange event triggered twice in table view

Classic Servoy
1

We have a problem that in a certain situation the onDataChange event is triggered twice. Reproducable when:

  • you have a table view
  • ondatachange event on some field
  • if you have calculations on the form table

If you don’t have calculations on the form table, the onDataChange event works correctly, so it seems that triggering the calculations on a table view makes the onDataChange event trigger twice. (doesn’t happen with list view)

we are testing this with bizlaf from centigrade, I thought it could be a problem with the LAF, but it seems to also happen with other LAFs. So maybe this is a Servoy bug?

we tested this on Servoy 6.0.4 - build 1227, and the newly released 6.0.5 - build 1230.

What oldValue/newValue you have for the events? Maybe this gives a clue on what happens.

Both times the oldValue en newValue are the same. We still have this problem… It really seems like a bug.

Please open then a case (with sample or some way to reproduce this).

Finally had the chance to try everything and found the problem :) :

The problem of the onDataChange event getting fired twice happens when the field has a GlobalMethodValidator set. When set, and when the onDataChange field is set on a table view, the onDataChange event gets triggered twice.

I will open a case with sample solution. (Done: SVY-1542)
