RichFaces : Client Side Pagination Not Working

[sategroup]

Hi,

I am using RichFaces 4.3.0 and JSF 2.1.

I am uploading data from a text file with an option to filter data based on some condition. The non-filtered data is saved in the DB, whereas, the filtered/not-required data is NOT saved on DB and is only displayed to the user along with info like what was wrong with the data.

This filter/not-required data is displayed in <rich:dataTable> along with <rich:dataScroller> using a bean that has a request scope. I do get the pages at the bottom of the table, but when I try to click on the page, nothing happens as if the request never went through. I checked the console using Developer Tools - F12 on IE and saw that Ajax request didn't process anything. I believe Request Scope could be the issue for this behavior. For that I changed the scope to View Scope, but then the data was not displayed at all. I don't want to use Session Scope for this. Is there a better way of doing this?

Can anyone please help me find the issue or help me out with a small sample app that allows client side pagination using richfaces & without session scope? Since, I am working on this for my client, I can't disclose the code.

I even tried using jquery, but even that didn't work out with RF tags.

Thanks

Hemant

To be clear, does your pagination work with @SessionScoped, but you just prefer not to use @SessionScoped?

Have you compared your impl to what's available on the RichFaces showcase?

Commercial support for RichFacesis available for those who are not able to work within the confines of the OSS community:

Hey Brian,

Its working fine with SessionScope but I don't prefer to use it as using SessionScope has its own implications, when all I want is show some data on client side & enable pagination on client side without hitting the backend again and again. I had already checked their showcase and in their example they are using SessionScope.

If I had to use SessionScope only, then what's the point of providing a ViewScope?

As for commercial support, that is not an option for me.

ViewScoped should work.

Hi,

Finally, I was able to discover the problem. Thanks to StackOverflow.com. Although, I was using the viewScope, my method was returning a String rather than returning null or void. After I changed the method definition to void, the code started working properly.

Seems like void or null forces JSF to re-instantiate the object with old data...

Thanks Brian for reading and replying to my problem.
