  See attached sample (sorry for the german texts, I picked the tree data from our real app, as I could not reproduce it with sample data):
  
  FlexNodeExpanded.zip
  
  I build a C1FlexGrid tree, and directly after populating the child nodes of a parent node, I might collapse this parent node. Then I add further sibling nodes.
  
  The result is that some parts of the tree are not visible.

  This is the expected result (I collapsed all child nodes to make the tree structure clearer) - three child nodes are missing :
  
  

  

  802×482 6.57 KB

  And this is the actual result (again I collapsed child nodes for better visibility):
  
  

  

  802×482 6.22 KB

  All rows get visible again if I collapse and expand the root node.

  This worked in .631, so I assume there is a regression.

  A workaround could be to first populate the full tree, then collapse the nodes (this code is commented in the sample)

  Best regards

  Hi Wolfgang,

  As per the development team, this is a regression due to another change, and here is the updated tracking ID as you requested ;-).

  I spoke too soon - in our real world app, there are still invisible nodes - seems to affect toplevel nodes.
  
  See attached reworked sample:
  
  FlexNodeExpanded_643.zip

  This is the grid with .631:
  
  

  

  802×482 5.35 KB

  And this is the broken version - toplevel nodes at the end are invisible:
  
  

  

  802×482 5.5 KB

  Best regards
