> It is impossible to specify tree in jtree widgets.
> Only adding root node works without problem:
> jtree .tree
> .tree node add root "Root node"
> Now when I try to add other nodes command failed
> .tree node add 0 "First node"

> Now these commands work
> .tree node add -1 "First node"
> .tree node add -1 "Second node"
> .tree node add -1 "Third node"
> .tree node add 0 "Second level node"
> .tree node add {0 0} "Third level node"
> My version of SwkJTreeWidgetCmd.java file is included as attachment
