Subject Re: Issue with the t:dataScroller
Date Tue, 27 Feb 2007 15:59:44 GMT
Hello Mike,

what do you mean with 'placeholder for a better solution'? I think, the 
right way to solve this problem should be to improve the dataTable, i.e. 
with 'autoreset' property without needing to track any events in other 
components. This property cann be then false by default for backward 
compatibility (hovever, I can't imaginate any usecase for this behaviour)
Any other solution will be IMHO some kind of workaround :)
