Problem upgrading TreePanel from 1.1.2 to 1.2

[joe1chen]

Hi,
I have a Ext Designer 1.1.2 ExtJS 3 project that I upgraded using the 1.2.1 beta. I ran into a problem with the TreePanel. I have a TreePanel that I promoted to a class in 1.1.2. The problem is that in 1.2.1, I am unable to see any of the nodes in the tree (both in the designer as well as in the browser). Finally, I discovered that the Ext Designer 1.2.1 did not migrate the TreePanel definitions properly.

Here is an example of the 1.1.2 tree node definition in the xds:

{
                            "id": "MyTreeNode1",
                            "type": "treenode",
                            "reference": {
                                "name": "items",
                                "type": "array"
                            },
                            "codeClass": null,
                            "userConfig": {
                                "allowDrag": false,
                                "allowDrop": false,
                                "editable": false,
                                "expandable": true,
                                "expanded": true,
                                "id": "editionsNode",
                                "leaf": true,
                                "singleClickExpand": true,
                                "text": "My News Editions",
                                "designer|userClassName": "MyTreeNode1"
                            }
                        }

I had to manually change "name":"items" to "name":"children" and then it works in 1.2.1.

Here's the working code in 1.2.1:

{
                            "id": "MyTreeNode1",
                            "type": "treenode",
                            "reference": {
                                "name": "children",
                                "type": "array"
                            },
                            "codeClass": null,
                            "userConfig": {
                                "allowDrag": false,
                                "allowDrop": false,
                                "editable": false,
                                "expandable": true,
                                "expanded": true,
                                "id": "editionsNode",
                                "leaf": true,
                                "singleClickExpand": true,
                                "text": "My News Editions",
                                "designer|userClassName": "MyTreeNode1"
                            }
                        }
