Dynamic mandatory field error message is not getting displayed in webui

Hi,

In Appointment if the importance is HIGH i made Location as mandatory.For this i enhanced BT126H_APPT/ApptDetails. In the get_p_location() method of BTACTIVITYYH i have written the code.

Now the problem is Error message for this dynamic mandatory field is not getting displayed in webui.

I debugged in DO_FINISH_INPUT error message is getting generated but it is not getting displayed in ui.

Can anybody tell where the problem is?

Thanks,

Hari.
