Grid with custom EditorErrorHandler

Hi,

We would like to have custom editor error handler to show cell specific messages similar to one showed in attachment.
I tried adding my own MyDefaultEditorErrorHandler but its not getting called. Using un-buffered grid.
From docs it should be possible, but let me know how it can be done?

Thanks,
Ram

Ping… Any pointers?

Hmm…Looks like this is again invoked for buffered grid.
