919568 - Multiple CustomEvent breaks

Status: RESOLVED FIXED

(Add-on SDK Graveyard :: General, defect)

Description

[Kailas]

CustomEvent is invoked only once.  To communicate from unprivileged page to privilege page When CustomEvents are used then it is invoked only once.

CustomEvent (event name = downloadReport) Dispatch is implemented at: https://github.com/patilkr/CustomEventError/blob/master/data/securityReport.js#L69

and CustomEvent Listener: https://github.com/patilkr/CustomEventError/blob/master/lib/securityReportUI.js#L52

Only the first time dispatch of CustomEvent invoked Listener. 

In similar fashion of 2nd CustomEvent (Event name = addon-meesage) is added:
 2nd CustomEvent dispatch and Listener.
 https://github.com/patilkr/CustomEventError/blob/master/data/securityReport.js#L63
https://github.com/patilkr/CustomEventError/blob/master/lib/securityReportUI.js#L58

Listener of "addon-message" CustomEvent is invoked multiple times as long as "downloadReport" CustomEvent is not triggered. But after first use of "downloadReport" CustomEvent, both event stops working and no error is reported in error console.

The error was caused because the listener was not there for second time dispatch of CustomEvent.
It was because the CustomEvent dispatch from UI occurs through a anchor element that reload the developer tools UI page. Therefore, listener function is not available for CustomEvent dispatch. 
It's not a FF bug rather it was a problem in the sample code.
