Is there a way to check if the DOM has changed since load of the page? For example, I have a widget that connects a click event to a certain class during the "_setupEvents" function. However, if there are required fields and an "alert" class appears, I want to capture this via the "dojo.query" method and then stop execution of the widget. Is there a way to capture the click event of the class and check the DOM?
You should be able to use the data.subscribe() function in the Mendix clientside API to view if there are any changes and also validation alerts on a certain object and its attributes.
