[jboss-user] [JBoss Seam] - EntityHome, ajax4JSF and Pagination

[gledson.rabelo]

Hi,

I'm using the Seam EntityHome and Ajax4JSF for developing ajax enabled CRUDs  with pagination. 

The data table has checkboxs that the user can select to delete many entities. 

When I go to the next page (>), the listPanel is rerendered and the checkboxs should be cleaned for the new entities of current page. 

But when I selected one checkbox and go to the next page, it remains checked in the next page.

And when I clicked in the Remove button ("Excluir") and I'm in the middle page, the ids of the first are sended for the removeChecked operation. 

My Code is listed  below.

Please, Could somebody help me?
