I was trying to use the tree view to populate a table on the same page with details about the object selected. The only way know of doing this is to create a non peristable object that represents the model and have a member of that object be the selected object of the tree view (or grid view). The microflow requires the 2 inputs. One being the model and the other being the object that was selected by the control. I was not able to do this in your tree view because it does not detect parent contexts or seem to have the ability to add a second input parameter to actions that are called from the selection of a node. Would it be possible to change this so it works like the other controls in mendix?
