Datascroller for a datatable | need help

[Anoop V. Kumar]

Hello,

Has somebody successfully used the datascroller component from Tomahawk? I need help in that.

Basically, I have implemented it and it works great in the initial display - all the links appear (first, last, next, before and page numbers) - but when I click on the links I get this error:

I have read somewhere that we need to write some code to actually make it work - but so far I have searched on google and on the wiki sites of myfaces.org and have not found the actual literature regarding this implementation.

Please let me know if there is such an explanation and do forward me the link or provide some pointers on what methods to implement / configuration.

Thanks,
Anoop
