[jbosstools-issues] [JBoss JIRA] Commented: (JBIDE-7688) Loading (instances, images) freezes the UI

    [ https://jira.jboss.org/browse/JBIDE-7688?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12567593#comment-12567593 ] 

Andre Dietisheim commented on JBIDE-7688:
-----------------------------------------

made a major overhaul in the ui code and moved a lot of dupllicate code in both viewers (InstanceView and ImageView) and in both filters (ImageFilter and InstanceFilter). This issue needs load operations to be executed in background threads. Instead of changing all involved components that have a lot of duplicate code, I decided to consolidate the code that shall be changed first. I'll then be able to change things at a single place.

> If you go to the cloud viewer and list a clouds instances or images for the first time, instances/images get loaded from the server. This is not done in a background job and UI freezes while the client is waiting for the server response.
> how to reproduce:
> 1) make sure you have at least 2 clouds: one with a lot of images (or instances), another one with a few images
> 2) make sure you have image view opened (or instance view, if you have a lot of instances on a cloud)
> 3) make sure to select the cloud with the few images in the image view (or do the same with instance view)
> 4) restart deltacloud client (eclipse)
> 5) go to image view and select the cloud with many images
> Result:
> Image view freezes while images get loaded
> Expected result:
> Image view is not freezed. A progress bar is displayed while images are loaded
