A simple push of data to my tree results in the following error. Have no idea why, any thoughts or ideas???

My push code

app.data.push({title:"New"})

the error i get:

[Vue warn]: Error in render: "TypeError: Cannot read property '0' of undefined"

found in

---> <TreeNode> at DraggableTreeNode.vue... (1 recursive calls)
       <Tree> at DraggableTree.vue
         <Root>

what's your template? I suspect that your template has a problem.
