Subject [jira] [Commented] (YARN-237) Refreshing the RM page forgets how many rows I had in my Datatables
Date Thu, 28 Feb 2013 22:49:13 GMT

    [ https://issues.apache.org/jira/browse/YARN-237?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13590009#comment-13590009

jian he commented on YARN-237:
------------------------------

Tried with latest version of firefox ,safari, chrome.It works. I will wrapper some code to
check if the browser doesn't support,then it goes back to previous way. And I'll catch the
exception you mentioned. 
The key is is already the id of the data table. This page has two data tables, one for listing
all nodes, and the other for 
listing all applications. That's why the state is saved separately for 'nodes' and 'applications'.
Lacking knowledge about jQuery and localStorage, not sure other potential problems.
