[richfaces-issues] [JBoss JIRA] (RF-11765) Datatable footer cell doesn't use all columns (wrong colspan generated)

[Brian Leathem (JIRA)]

     [ https://issues.jboss.org/browse/RF-11765?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Brian Leathem resolved RF-11765.
--------------------------------

    Fix Version/s:     (was: 4.2.0.CR1)
       Resolution: Won't Fix


On analysing the provided code sample I've concluded that the current behaviour is correct.  Consider the state while trying to count the number of columns while rendering the footer:

While rendering the footer, no row is active, hence rowNbr cannot return 0 (that would imply the 0th row is active).  It counts the number of rendered columns to determine what to use for the colspan - if a column is not rendered, it should not be included in the count.

Hence the appropriate solution is indeed to alter the render logic of the column, so that it is counted while rendering the footer.

> When specifying a datatable's header with rich:columnGroup and a rich:column in the tbody that has rendered="#{rowKeyNbr eq 0}" the wrong colspan for the table footer cell is generated.
