Multiple extendedDataTable on one page lead to a "Array index out of
range"-Exception when user resizes a column of one of them
-------------------------------------------------------------------------------------------------------------------------------
Key: RF-5976
URL: https://jira.jboss.org/jira/browse/RF-5976
Project: RichFaces
Issue Type: Bug
Affects Versions: 3.3.0
Reporter: Marcel Urbanek
Priority: Minor
When I use only one extendedDataTable on a page, everything is fine.
When I use two or more extendedDataTable, with different number of columns, I
get the following exception when I try to resize a column of the second table
(if the tables have a different number of columns):
Error 500: Array index out of range: 8
at
org.richfaces.component.ColumnsSizeState.changeColumnSize(ExtendedDataTableState.java:337)
Reason for that is the following: Richfaces seems to apply the changed column
sizes to all(?) extendedDataTable in the View. It gets a little clearer whe you
look at the requests that are submitted to the server:
AJAXREQUEST _viewRoot
columnResizeAction columnResizeAction
columnWidths 67;69;154;231;67;231;144;17;
This problem can be worked around, when I add a a4j:region around the tables.
The Ajaxrequest then looks like the following:
AJAXREQUEST j_id10:workingTableRegion
columnResizeAction columnResizeAction
columnWidths 67;67;156;231;67;314;61;17;
So only the affected table is updated, no Exception occurs then.
