Bug 1401576

I can not simulate this. What I can observe on the other hand is that there is a delay between pressing the OK and the dialog actually saving. Any chance this is a larger delay on your (I guess bigger) environment?

If not, could you please check if there are some error logs in the ui.log after the first pressing of the OK?

Hello,

It is not happening for every attempt now. sometime happens and at and other attempt not. I see following logs in ui.log when it fails:

I was waiting for more than a minute to respond to create disk but it still is not saving the configuration.

OK, so a null pointer - I would guess it to some race on async calls.

Could you please now provide the logs in an un-obfuscated way? E.g. install the ovirt-engine-webadmin-portal-debuginfo ovirt-engine-userportal-debuginfo, than restart the engine, simulate again and than take the logs.
Also please provide the exact version of the webadmin rpm.

thank you

Hi Tomas,
I have asked logs from customer environment who has reported the issues and able to reproduce the same in his environment. 

>>> exact version of the webadmin rpm.
~~~
rhevm-4.0.5.5-0.1.el7ev.noarch
ovirt-engine-webadmin-portal-4.0.5.5-0.1.el7ev.noarch

$ cat installed-rpms | grep debuginfo

The problem is that the event about the fact that the button was clicked is published as an event. Therefore, the order in which the following two events happen are unpredictable:
1: close the disk dialog
2: show VM dialog
3: update values in VM dialog

In most cases it is 1, 2 and than 3, but in some cases it can be 3, 1, 2. This leads to trying to update the properties of a widget which is not visible leading to exceptions.

Coincidentally, there is a different bug (https://bugzilla.redhat.com/show_bug.cgi?id=1391466) which requires not to hide the VM dialog if the disk dialog is shown which will ensure that the VM dialog is always present and regardless of the order of the events, the widgets can be updated. The https://bugzilla.redhat.com/show_bug.cgi?id=1391466 is targeted to 4.0.6 so setting target of this also for 4.0.6 for independent verification.

Hello, 
Also there is this message appeared while creating disk:

~~~
Uncaught exception occurred. Please try reloading the page. Details: Exception caught: Exception caught: (TypeError) __gwt$exception: <skipped>: a is null
Please have your administrator check the UI logs
~~~

Will this be addressed here or should I create a new bugzilla report. 
The screenshot is already attached with this bugzilla.

addressed here - that is the same issue reported in two different ways.

(Originally by Tomas Jelinek)

Great, thanks for the confirmation.
