    Multi-Node Tree Picker Error

    I'm working on a new project and suddenly all Multi-Node Tree Picker datatypes stopped working. They had worked fine before but now they all throw the following error:

    {"Message":"Object reference not set to an instance of an object.","StackTrace":"   at uComponents.Core.Shared.Tree.CustomTreeService.GetInitAppTreeData(String app, String treeType, Boolean showContextMenu, Boolean isDialog, TreeDialogModes dialogMode, String functionToCall, String nodeKey)","ExceptionType":"System.NullReferenceException"}

    Any ideas? I'm on Umbraco 4.7, .Net 4, IIS 7.5, uComponents 2.2.0.0

    Thanks,

    Matt

    Hi Matt,

    Thanks for reporting this.  I have seen this error a couple of times with the v2.2 beta.  However when I try to debug it, the app-pool is restarted and the error goes away - unable to reproduce the error again.

    Try touching the Web.config or restarting your app-pool, that will clear the problem for now.

    If you know of a way that we can reproduce the problem, let us know ... we'll get it fixed.

    Thanks, Lee.

    Same problem here. Restaring IIS fixes it.

    Request Url:
http://.../umbraco/plugins/uComponents/MultiNodePicker/CustomTreeService.asmx/GetInitAppTreeData

Posted data:
{'app':'media','showContextMenu':'false', 'isDialog':'true', 'dialogMode':'id', 'treeType':'FilteredMediaTree', 'functionToCall':'', 'nodeKey':'1466'}

Response in error state:
{
    "Message": "Object reference not set to an instance of an object.",
    "StackTrace": "   at uComponents.Core.Shared.Tree.CustomTreeService.GetInitAppTreeData(String app, String treeType, Boolean showContextMenu, Boolean isDialog, TreeDialogModes dialogMode, String functionToCall, String nodeKey)",
    "ExceptionType": "System.NullReferenceException"
}

Response after IIS reset:
{
    "d": {
        "json": "[{\"data\":{...}}]",
        "app": "media",
        "js": ""
    }
}

    umbraco v 4.7.2 (Assembly version: 1.0.4500.21031)

    uComponents 3.1.0
