@mdelanno - I’ve added in a configuration option called triggerScrollOffset which will allow you to determine how many pixels from teh bottom you need to be to initiate a new load operation. I’ve defaulted it to 150 and this seems to work pretty smoothly.

@Ronni - There was a bug that could be reproduced by scrolling to the bottom very quickly and then immediately scrolling up before the load operation was complete. This bug has been squashed and there is a newer copy up.

@Dave - This component certainly did not aim to compete with LiveGrid. I tried to address the use cases which you would use each of the classes in the paragraph titled “When should you use a LiveDataPanel?”

@Dave - I think Aaron was trying to show how simple it is to build the functionality Dzone offers on their page by extending a base Ext “Panel”. Thorsten Suckow’s implementation is very nice. I think both have their appropriate use cases.

I like the functionality, but from a usability standpoint, the size and positioning of the scroll-bar should represent the entire dataset regardless of how much has already been loaded. The “Live Grid” is a better implementation in my opinion:
