Reset datascroller to page one?

[rua]

Hi!

I am having a problem with a datatable and an associated datascroller. There is a search field in my page. Once a user enters some text, an action listener is called which connects to the database and loads the objects matching to the search criteria in a java.util.List. This list is used as value in the rich:datatable.

The user can paginate through the results with the datascroller. Everything works fine. But lets say the user scrolls to page 5 and then enters something new in the search field. The datascroller doesn't reset itself to page 1.

I tried binding and .setPage(1) of UIDatascroller in the actionListener of the search field but it didn't work out.

Any help would be most welcome!

On hitting new search do you reRender the datascroller?

Is that with a page refresh or an ajax request?

It's interesting to see that my pager stays on the same page, even when doing a new page request. Upon that request, I make some logging:

So it was on page 5, I do a new search, and the pager of the results is still on page 5, even though the displayed results are of page 1 of my new search...

ps: Resetting the pager as you can see in the log is done by:

cmpTable.setFirst(0);
cmpDataScroller.setPage(1);

Thanks Tomba. That was exactly the behaviour I had trouble with. The search uses a page refresh.

cmpTable.setFirst(0);
cmpDataScroller.setPage(1);

This helps! Thanks a lot! I did only setPage(1) but forgot setFirst(0) on the datatable.

I had rejoiced too soon. Tomba your solution works but it sets the datascroller to the last page not the first.

Let me explain the behaviour.

Lets say after a search there are 10 possible pages each having n rows. If I click on page 7 and then search again and the search yields equal or less than n results, only one page is displayed and the datascroller is not displayed at all. This is fine. This is what I was looking for.

However if my result yields 6 pages. Then the datascroller and the datatable display the last page. In my logs I find messages like this one:

The requested page #26 isn't found in the model containing 2 pages. Paging is reset to page #2

you could just use page attribute bound to some bean property and reset it when needed. So you will not use component binding at all.

Hi Ilya,

could you elaborate on this?

If I use the page attribute I get the initial behaviour. Calling the setter in my actionListener to 1 doesn't seem to have an effect at all. Its just ignored.
