Hi again
I wanted to turn on/off row visibility, and in doing that, I wanted to set row
id on the row.
I found out how this should be done, in overriding the newRowItem on the
DefaultDataTable class, and adding an AttributeModifier to the rowItem.
Sorry for any inconvenience.
Yours,
Tron Walseth

Emne: Re: Table row visibility
Hi,
What is your question ?
I guess "how to get the markup id of the row?".
I'd suggest you to add a JS event listener on the <table> that filters for
clicks on 'tr' (i.e. event delegation).
