Odd behaviour in rich:dataTable using rows and rich:datascroller

[elisei]

Hi all,

I experience some strange behaviour using rich:dataTable with rows and rich:datascroller. I have a normal datatable and a datascroller in the footer. Everything works fine, except this:

When I change rows from a smaller number to a bigger number, while the displayed page is for example 2, (datatable will then be rerendered) and only one page should be displayed (instead of two or more pages including datascroller), not all rows are beeing displayed. Just the rows beginning from the frist element of the second page. This is strange.

I tried manually setting page number to 1, but no change in behaviour occured.

How can I set the counter from element 0 to element n of the dataTable?

Many thanks in advance,

/Elisei

Actually my problem is something like this:

https://issues.jboss.org/browse/RF-10120

My workaround was to manually set page to 1, every time number of displayed rows change. This works fine. Only if I change from page 2, to only one result page... then not all elements are displayed.

Update:

Ok. The problem seems to be in my own implemented DataModel. I followed exactly this post:

http://community.jboss.org/message/602726

Now, Richfaces calls the walk Method with firstMethod always > 0, and so, my walk method always retrieves then firstRow (which is >0) to lastRow, which are not all elements. Element 0 to firstRow (which is >0) are not rendered therefore ...
