Add and update details as input mashup
Hi community,
So I have a main mashup in which i have some data visible in two label widgets.I also have a button below which is used to navigate to a popup.The purpose of this popup is to get new values for the labels in the mashup.So how do I get the values from the user and save it such a way that as soon as I close the popup the main mashup updates to the new values i.e the old values in both the label widgets are replaced by the new values the user has given now.
Also I want to validate that the user has entered both the values in both the labels,and even if one label is empty i need to display a msg.How do I do that?
