[jboss-user] [JBoss Seam] - Re: Is it a bug? EntityQuery refresh before update model

Thu Apr 26 10:02:31 EDT 2007

Hi Pete, Thanks for your reply. 

I'm using 1.2.1.GA. 

I'm using pagination with selectable rows. When I go to the next page, I want send to the back bean the rows selected in the current page. 

But, the refresh of query is performed before of  update the back bean and it's receive data of next page (because the EntityQuery refresh 	
already occurred). 

I will go to illustrate with an example: 

Current Page Rows: 

Marked   Value
false    value1
true    value2
true     value3 
false    value4

When I submit and go to the next page the refresh is first performed returning  values (value5, value6, value7, value8) and after the model is updated  with the values below and the next page is shown:

Marked   Value
false    value1
true    value2
true     value3 
false    value4

So, probably had the premature  EntityQuery refresh , the model is updated incorrectly.

My Code is Listed below:
