Custom validation called multiple times

[Ryan]

Custom validation is called twice for a single input field. When navigatable/selectable configuration is set and enter is pressed the row is saved and validation is called three times for a single input field.

Hi Ryan,

Calling the validation functions twice is expected in this case, because pressing Enter with the navigatable option enabled is trying to save the changes. First, the validation is called because the input element lost focus, next it is called because the row is being saved.

I expect that as well for navigatable but it isn't being called twice - its being called three times. Here's a demo without navigatable that shows validation erroneously being called twice. http://dojo.telerik.com/oxeKE/2

Hello again Ryan,

Would you please let me know which browser you are using? I tried reproducing this with Chrome, Firefox and IE10, but the validation is called once in the second example and twice in the first.

Hi Alex. Here's a video demonstrating the bug in all three browsers as well as their version numbers. I moved the console above the grid so I could record a smaller video.

Hi Ryan,

I am not sure I understand your point correctly. You mentioned that this happens when pressing the Enter key, however the screencast shows that the update button is clicked. Clicking the button makes the input element lose focus, thus the Validation is triggered. It also tries to save the changes, triggering the Validation again. This is expected and is unlikely to change.
