Hi Jun,
Thank you for your reply..
I'm using XML and Js Views, My XML Code for Combo box is.
<ComboBox enabled="{= ${viewModel>/mode} === 'edit'? false: true}" items="{ path: '/ETY_LEAVE_TYPESSet', sorter: { path: 'Zhrlvtype' } }"
placeholder="{i18n>leaveType}" value="{Zhrlvtype}">
<core:Item key="{Zhrlvtype}" text="{Subtx}"/>
</ComboBox>
Cheers,
San..
