Datatable selection large dataset

[Error]

Hi there.

My application is using:
WildFly 8.2
Mojarra 2.2.8-jbossorg-1 (the one that comes with WildFly).
Primefaces 5.2
JDK8

There's a page where I need to load many files (around 12k) and then show their names to the user so he/she can choose which ones they want to pick up.

And I'm able to show my datatable with the files as expected.
The problem starts when I select more than 1k rows and try to go to the next page of the datatable.
It gets incredibly slow.

I use multiple selection with checkboxes, and from what I saw every time I change the page it sends every checkbox as a parameter from the request.
I really have no idea of how to solve this. Hope someone might help with any suggestion.

Thanks

Try the PrimeFaces partial submit on the ajax tag.

Hi kukeltje, thank you for answering me [here and on StackOverflow =) ], however that didn't solve it.

I think there's something to do with fact that primefaces need to compare both list on every page to check whick rows are selected.

So, instead of using the common selection I created a DTO with a boolean column, this way it worked.

Thank you again.
