    [CLOSED] Bug on plugins?

    I'm trying to create a plugin to encapsulate some javascript code for specific components (instead of inherit the whole component). So far, it works fine, but, when I tried to inherit from an existing plugin, MY init function is not called anymore.

    Ex.:
    public sealed class OrganogramNodeTreeViewDragDropPlugin : TreeViewDragDrop
{

    public override string InstanceOf
    {
        get { return "TMC.ux.OrganogramNodeTreeViewDragDropPlugin"; }
    }

}
    This doesn't work (the init method of my script is never called). The DragNDrop works fine in this case.

    public sealed class OrganogramNodeTreeViewDragDropPlugin : Plugin
{

    public override string InstanceOf
    {
        get { return "TMC.ux.OrganogramNodeTreeViewDragDropPlugin"; }
    }

}
    This works fine (my plugin is initialized). Notice that I just changed the inheritance part. No scripts were changed.

    In both cases, my script inherits from the correct base plugin:

    Ext.define("TMC.ux.OrganogramNodeTreeViewDragDropPlugin",
    {
        extend: "Ext.tree.plugin.TreeViewDragDrop",
        alias: "plugin.tmcorganogramnodetreeviewdragdrop",
        treeView: null,
        
        init: function (treeView)
        {
            debugger;
            console.dir(arguments);
            this.callParent(arguments);
            this.treeView = treeView;
        }
    });
    What I want to do is create a specific plugin that could handle some server-side code on initialization, but inheriting from an existing plugin:

        public OrganogramNodeTreeViewDragDropPlugin()
    {
        AllowLeafDrop = true;
        AppendOnly = true;
        DDGroup = "OrganogramNodesEditor";
        DragGroup = "OrganogramNodesEditor";
        DropGroup = "OrganogramNodesEditor";
        NodeHighlightOnDrop = true;
        NodeHighlightOnRepair = true;
    }
    But I can't, because server side plugins works, but doesn't trigger the init method of MY script when inheriting anything but Plugin class =\

    Hi @Periscope,

    It appears to be working for me. Here is a test case. Could you provide your test case?

    Example
    <%@ Page Language="C#" %>

<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>

<script runat="server">    
    public sealed class TestPlugin : Plugin
    {
        public override string InstanceOf
        {
            get { return "Ext.tree.plugin.TestPlugin"; }
        }
    }

    protected void Page_Load(object sender, EventArgs e)
    {
        this.TreeView1.Plugins.Add(new TestPlugin());
    }

</script>

<!DOCTYPE html>
<html>
<head runat="server">
    <title>Ext.NET v2 Example</title>

    <script>
        Ext.define("Ext.tree.plugin.TestPlugin", {
            extend: "Ext.tree.plugin.TreeViewDragDrop",
            alias: "plugin.testplugin",

            init: function () {
                alert("I am within the init function")
                this.callParent(arguments);
            }
        });
    </script>
</head>
<body>
    <form runat="server">
        <ext:ResourceManager runat="server" />
        <ext:TreePanel runat="server">
            <Root>
                <ext:Node Text="Root (level 0)" Expanded="true">
                    <Children>
                        <ext:Node Text="Node1 (level 1)" Expanded="true">
                            <Children>
                                <ext:Node Text="Node1 (level 2)" Leaf="true" />
                            </Children>
                        </ext:Node>
                    </Children>
                </ext:Node>
            </Root>
            <View>
                <ext:TreeView ID="TreeView1" runat="server" />
            </View>
        </ext:TreePanel>
    </form>
</body>
</html>
    By the way, you might need to override a Plugin's PType property as well.

    My test case is the same of yours, just change the following line and the alert isn't displayed anymore:

    public sealed class TestPlugin : Ext.Net.TreeViewDragDrop

    Well, as I said, you should override the PType property as well.

    Example
    public sealed class TestPlugin : Ext.Net.TreeViewDragDrop
{
    public override string InstanceOf
    {
        get { return "Ext.tree.plugin.TestPlugin"; }
    }

    public override string PType
    {
        get 
        { 
                return "testplugin";
        }
    }
}
