How to know whether current row is new row or from database?

A row or view has four states:

• New
• Modified
• Un-Modified
• Initialized

To get the state using expression: #{row.row.entities[0].entityState}

You can use this expression to control the display or rows in the UI. Like to display new rows in diff colors.

    Ex: #{row.row.entities[0].entityState==0 ? 'background-color:yellow' :  ''} 

Now in RowImpl, you can access the state using:

    Ex: byte entityState = this.getEntity(0).getEntityState()
