Description jeanfrancoisdenise 2013-11-29 17:36:09 UTC 
It appears that, during a debugging session, all the properties of the current instance are retrieved in order to be displayed in the Variables tab.


If one of these properties throw an Exception then a popup window is displayed and refreshed on each step.

This exception should be caught and displayed as the value of the properties in the variables tab.

This has been observed for instance with property getter tha tare actually executing some code. For example, in avatar.js, when a deprecated member is accessed, avatar.js is throwing an Exception.
Comment 1 Martin Entlicher 2013-11-29 17:49:41 UTC 
This is similar to issue #225959.
I agree that no popup window should be displayed from Variables. Any problem in target code can be displayed as a variable value.
