Getting NullPointerException when opening loginWindow from button click

Support
#1

Hi,

I am getting this nullpointer exception when trying to open an extended loginWindow screen from a created button.

I have changed my landing screen to be an extended mainWindow screen that has a button login/register and i am trying to call the loginWindow screen from this button. Since the anonymous is the account used to get to this page i have copied the administrator role and set it for anonymous user with access to all screen.

null%20exception

Any help on how to achieve this.

Hi,

You cannot show loginWindow as usual window, because it can be shown only by replacing the main one:

App.getInstance().navigateTo('loginWindow');

That is dangerous, you can implicitly show some data and functionality for non-logged in users.

Hi,

@artamonov i have used the code you gave me above and now i am getting “Unexpected error Please contact system administrator”.

I have removed adminstrator role and gave anonymous role to anonymous user and allowed access to the loginWindow for anonymous role
