[jira] [Commented] (AMBARI-3999) Long host names are inconvenient for viewing in background operations popup

["Yusaku Sako (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/AMBARI-3999?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13844685#comment-13844685 ] 

Yusaku Sako commented on AMBARI-3999:
-------------------------------------

[~xiwang0309], "hosts" computed property depending on "hosts" is self referential.  I suppose Ember is OK with it but this seems a bit odd.
Also, a computed property should not have side effects (as opposed to observers).
A cleaner fix might be to define the displayName computed property for the host object itself, or make an observer to set the displayName.

> Steps:
> # Open background operations window and select any operation.
> Result: 
> If the host name is too long, they are not placed on designated place.
> Solution:
> If the host name is too long, we show part of the string with "..." at the end.
> Also the string should keep in a single line all the time
