Testing & Debugging
Once the Chrome debugger has been opened, it will remain open in the background. Click Reload Page and the Chrome debugger will popup whenever debugger; is encountered. You can also click the Open Chrome Debugger link to bring the Chrome debugger to the foreground.
If you are using Working Preview, the Working Preview window can be detached from the designer. When detached, you can make changes to the component in Design mode and see the changes right away in the Working Preview window. The Refresh button will update the Working Preview. You can also turn on auto-refresh. Auto-refresh will immediately update Working Preview when any change is made to the component. If you component has a lot of controls or is complex, however, you may notice a delay while editing with auto-refresh on.
