Seam Query Component - pagination mystery
(New to SEAM and RichFaces)
I'd like to have a search capability
on my main form to help the user filling out a specific inputText field.
I decided to implement it with a rich:modalpanel, with the help of some javascript to bring back the desired value to my initial inputtext on the main page.
Inside my modal panel I have a search field and a search result grid (rich:datatable) backed by a SEAM Query Component. I'd like the grid to be paginated.
The problem I face is that the Next-Page, Last-Page links work well, but the previous-page, first-page doesn't do anything. I try to debug, but it seems that the firstResult
variable get never updated when I click previous-page/first-page....The scope of my Query component is the default one (EVENT).
In the Ajax Debug window I can see that the 'firstResult' parameter is passed in the request...
Any pointers would be appreciated.
