Additional Information

-- Check this doc about about supported client side API's look under GliderRecord class.

-- If this is not your solution but symptoms are same. Check if your client script have "g_form.setValue('<field>',' ')" or clearvalue(). These method clear or set the value and also clear the message. Make sure add these lines before g_form.showFieldMsg()

Example:

This will clear the message and value both:

g_form.setValue('outage_end','');

Add setvalue before showFieldMsg:

g_form.setValue('outage_end','');
