Hello,

I am using Border tree layout of mind fusion. I am saving the collapsed/expanded state of the nodes and drawing diagram after loading the states. It is working in some cases but when the parent node has more than one children and both the children's have expanded =false and saved then parent node has + icon besides it and one of the child is still shown (refer attachment).Diagram representation is attached.
Any idea why + icon is displayed at node 3 instead of - also why 4th node is still visible when its parent has expanded
=false .

Hello,

Tried to set the collapsed state after the diagram is fully created with nodes and links but still the same issue.
Setting the expanded =false in the node from diagrams nodes array.

It should work as instead of clicking the '+,-' icon, I am setting the expanded value on the node itself but getting the same error mentioned previously.

I am using node.setExpanded(...)

Hi,

Try setting the property in child-to-parent direction starting closest to leaf nodes, e.g. this should work with your test -

   diagram.getNodes()[3].setExpanded(false);
   diagram.getNodes()[2].setExpanded(false);
   diagram.getNodes()[0].setExpanded(false);
 

That's how users would hide these branches interactively (otherwise they would not see children to collapse) and the control saves some state along the way that gets invalid if starting from the root.
