DataProcessor - Tree Render Shows as Inserted Transactions

Suite and Optimus Suite 5
#1

I trying to build a tree view with DataConnector and DataProcessor to write the changes back. But I see that when the tree first renders all elements that are drawn on the screen are sent back through DataProcessor as an ‘inserted’ traction. This causes all the entires in the db to be duplicated. New child entries that I add on the GUI manually also come across the DataProcessor as ‘inserted’. How do I differentiate them?

Please try to remove the next line

tree.enableSmartRendering(true);
#3

Thank you that worked. How will disabling smart render affect the performance of larger trees?

#4

If you have not too many items per level ( lets say less than 1000 items per level ) - tree will work fine without smart rendering mode

#5

Can I have your entire directory with files please? Because I can’t understand these examples. Thanks
