We have requirement to give tag filed component to end user to select tags which are created in tag console. We have five types of meta data in page properties so we used tag filed component five time to select tags separately for each meta data. Now the requirement is to allow user to select only one tag for first tag field component,two tags for second tag field component. We had same requirement on page properties also so we added maximum properties under namespace and it works fine but incase of tag field component we don't have any place to add . we tried to add listeners in component jsp for before submit function but it didn't worked.
