How to fix "App Already Bootstrapped with this Element"? - angularjs

I just upgraded the Angular to 1.2.8.
I am initializing and opening a model from GWT using $wnd.angular.bootstrap($doc, ['fmEventLogApp']);
After closing the model, when I try to open the model again, it is trying to reinitialize the model again and throwing an error as "uncaught exception: com.google.gwt.event.shared.UmbrellaException: One or more exceptions caught, see full set in UmbrellaException#getCauses"
But when I see the actual error message, it says "App Already Bootstrapped with this Element".
How to solve this problem in case of a model window? Please help.

Why Do I Get a Blank Page on an Error but other people don't

I am watching this video and when an error occurs he gets an actual error on the page and only a blank white screen when he deploys the site.
I see this a few times. However I only see white screen no matter if I am on local host or on production.
I see he is using chrome on Mac and I am using it on PC. Not sure if that is the difference.
While I can't say definitively, my suspicion is that you aren't using create-react-app to setup your project.
You will only see that error message if you have used CRA to set up your project, as that is a specific error handler that is baked into that project. If you're not using create-react-app, React should log an error to your console instead.
ReactJS smart enough to hide the errors to the users when the app is in production mode.
You will see only a blank page if the app gets crashed but if you inspect the page you will see small detail about the error in the console.
if you running the app in development mode you will see full details about the errors.
for this case cames componentDidCatch method to handle app crash errors, instead of the blank page display a “Something went wrong” message to the user or you can send XHR request to the server with the error info.

CakePHP unknown exception thrown

After successfully testing my app locally, I've pushed it to the remote server for further testing. But there, on each and every page, I get the following fatal error: Fatal error: Exception thrown without a stack frame in Unknown on line 0. What can be the cause of this?
if there was error with the code then there must have been an entry in apache's log. Also, with debug level set, it would definately have given errors unless you have defined your own custom exception handlers. so after all could it be whitespaces ?
It is not mandatory to have closing php tags in php pages unless you have other scripts below. I once struggled with it for days. If it is occuring in every page, you can check it once on the default layout, you could also test by commenting every includes in default layout to see if the problem is caused in some other script common to the application.
