[Holger Walter (JIRA)]

     [ https://issues.jboss.org/browse/RF-13615?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Holger Walter updated RF-13615:
-------------------------------

    Description: 

1. Go to the extendedDataTable showcase
2. Turn on ajax loading.
3. Open the debugger of your browser and watch the network communication
4. Scroll down in the table untli new data has to be fetched.
=> one POST request is sent. This is fine.
5. Change the width of a column in the table.
=> one POST request is sent. This is fine.
6. Scroll again in the table untli new data has to be fetched.
-> 2 POST requests are sent. WHY?
>From now on, on each scroll, the table always sends 2 requests. This behavior stops only when your relaod the table.

Due to this behavior I get some perfromance issues, as I have to execute some own javascript after each request.

Is there a possibility to prevent the 2nd POST request. I would be happy even with a dirty hack, or just a hint showing me from where the 2nd request is triggered.

Best regards
