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/browse/RF-5976 Project: RichFaces Issue Type: Bug Security Level: Public(Everyone can see) Affects Versions: 3.3.0 Reporter: Marcel Urbanek Priority: Minor Fix For: Future 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.
