Hello Vikas,

I think that is not possible via the server side, however you can try it with Data Policies as described here:

Hi,

From what i understand you can use. Something like to this with the condition and error message 

current.setAbortAction(true);
ction.setRedirectURL(current);

Hi,

I would prefer using client side code in UI action so that user knows which field is mandatory.

you cannot make field mandatory from server side as that has to run on client side.

but what you can do is this

1) check the field value is empty or not in server side

2) if empty then throw error that field is not populated

Something like this

if(current.field == ''){
	gs.addErrorMessage("You should fill the field value for field name");
	current.setAbortAction(true);
	action.setRedirectURL(current);
}
