Holger Walter created RF-13615:
----------------------------------
Summary: ExtendedDataTable: double ajax request on scrolling
Key: RF-13615
URL: https://issues.jboss.org/browse/RF-13615
Project: RichFaces
Issue Type: Bug
Security Level: Public (Everyone can see)
Components: showcase
Affects Versions: 4.3.5
Environment: Problem can be tested in richfaces showcase.
http://showcase.richfaces.org/richfaces/component-sample.jsf?demo=extendedDataTable&skin=blueSky
Reporter: Holger Walter
Affects version 4.3.6 - but issue tracker complained, that 4.3.6 does not exist
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
wlh
