Stopping update rendering when using OverwriteTable

Is there an easy way to stop an update from rendering to screen when using an OverwriteTable.

What I would like to do is look at the data in the update in JavaScript and if it contains certain values ensure the update doesn't occur.

It probably depends on what you mean with "easy" :D

You could rollback by hand the update using the onChangingValues callback and the setFormattedValue: if you set the formatted value of a field to null, it will not change in your view.

<br /> table.onChangingValues = function(itemPos, visualUpdateInfo, itemName) {<br /> [...]<br /> visualUpdateInfo.setFormattedValue("my_field",null );<br /> [...]<br /> };<br />
