Subject Amber 1.7.0 "Uncaught TypeError: Cannot read property 'set' of undefined"
Date Wed, 04 Mar 2015 22:43:05 GMT
Hi,
After starting all services, when I click on HDFS:Summary the main part of the page comes
back blank and all links to other services throw the following error:
Uncaught Error: assertion failed: Emptying a view in the inBuffer state is not allowed and
should not happen under normal circumstances. Most likely there is a bug in your application.
This may be due to excessive property change notifications.

I can however access the HDFS:Configs tab is navigated to from the config tab of another service.

When the HDFS:Summary page comes up blank the following errors are thrown:

Starts with these messages:
messages.js:1373  App.componentsStateMapper execution time: 12.446ms
serverValidator.js:72  App.serviceMetricsMapper execution time: 90.331ms
ember-latest.js:20014  STATEMANAGER: Sending event 'showInfo' to state root.main.services.service.
 
ember-latest.js:20327  STATEMANAGER: Entering root.main.services.service.summary

And ends with is:
serverValidator.js:72 App.serviceMetricsMapper execution time: 97.308ms

The main error is "Uncaught TypeError: Cannot read property 'set' of undefined" followed by
an ember stacktrace of sorts (utter gibberish):
