Hello,

I've sent an individual reply to each Support ticket in which the discussed here bug was reported. 

The two cases reported by John and Andy happened to be triggered by different sources. The fix for the described here bug report will be introduced in our next LIB(Latest Internal Build) which is expected to be released this Tuesday or Wednesday. If there are no new issues with it, the fix will be officially released with the next official release planned for 18.09.2019. 

The solution for the case reported by Andy is to use the setDataSource method of the TreeView instead of the DataSource data method when updating the DataSource of a given TreeView. 

Please check your ticket threads for details about each of the cases.  

Regards,
Petar

This issue is impacting our customers in their production environment, effectively making the application unusable.  It has been escalated by a number of our customers.

Same issue found. We do require a fix asap for this issue as it's causing major issues with performance using this tool.
