Hi Friends,

I am new to ROR.I have implemented sorting by Ajax drag and drop and  
interaction with database.  
Working fine but if i sort records rapidly, getting nil point exception.

I am pasting the sortable list code.

\<%= sortable\_element(‘sortable\_charts’,  
:update =\> ‘assigned\_chart\_files’,  
:url =\> {:action =\> :update\_positions , :quiz\_id  
=\> @quiz.id },  
:before =\> “Element.show(‘spinner’)”,  
:success =\> “Element.hide(‘spinner’)”)%\>

Also tryed with :frequecy =\> 3 or 4,or 2 but ssame error.

Nil point error is getting when i sort records rapidly.Normally it is  
working fine.

Can u give any advice?

I hope i wil get solution…

Regards,
