[CLOSED] Error when deleting a tree leaf

[Sharon]

Hi,

if I click a button, I want to append a new leaf on a selected node of my tree. Works as expected, i can select the leaf and the appropriate page is loaded.
If I try to delete the leaf just after it was created I get two javascript errors:

<div class="logRow logRow-errorMessage"><div class="errorTitle">Ext is not defined
<div class="errorSourceBox errorSource-exec">[img]chrome://firebug/content/blank.gif[/img]            Ext.fly(this.elNode).removeClass(cls);  
<a class="objectLink objectLink-sourceLink">
</a>
<div class="errorTitle">Ext is not defined
<div class="errorSourceBox errorSource-exec">[img]chrome://firebug/content/blank.gif[/img]            Ext.fly(this.elNode).addClass(cls);

I create the leaf with this code:

      function PutInFolder() {
          var node = parent.window.BinderTree.getNodeById(parent.window.CurrentNodeID.getValue());
          var nodeIds = node.id.split('!');
          var oldNode = node.findChild('id', nodeIds[0] + '!' + parent.window.CurrentPackageID.getValue());
          if (oldNode == null) {
              var newNode = new Ext.tree.AsyncTreeNode({
                  id: nodeIds[0] + '!' + parent.window.CurrentPackageID.getValue(),
                  text: parent.window.CurrentNodeName.getValue(),
                  cls: 'page-create',
                  leaf: true
              });
              node.expand(); 
              node.appendChild(newNode);
          }
      }

I delete a leaf with this code:

      function RemoveFromFolder() {
          if (parent.window.CurrentDocID.getValue() != '') {
              var parentNodeId = parent.window.ParentNodeID.getValue();
              if (parentNodeId != '' && parentNodeId.contains('!'))
              {
                  var parentNode = parent.window.BinderTree.getNodeById(parentNodeId);
                  if(parentNode.id.contains('!'))
                  {
                      var parentIds = parentNode.id.split('!');
                      var node = parentNode.findChild('id', parentIds[1] + '!' + parent.window.CurrentDocID.getValue());
                      if (node != null) {
                          node.remove();
                      }
                  }
              }
          }
      }

The code for the buttons is:

        void    CreateToolbar(bool update)
        {
            Toolbar tb = new Toolbar();

            mapButton = new ToolbarButton();
            mapButton.Icon = Icon.FolderAdd;
            mapButton.AjaxEvents.Click.Before = "parent.window.StatusBar.showBusy();";
            mapButton.Text = "Unter markierter Mappe einhängen";
            mapButton.AjaxEvents.Click.Event += new ComponentAjaxEvent.AjaxEventHandler(this.AddToMap);
            mapButton.AjaxEvents.Click.ExtraParams.Add(new Coolite.Ext.Web.Parameter("NodeID", "parent.window.CurrentNodeID.getValue()", ParameterMode.Raw));
            mapButton.AjaxEvents.Click.EventMask.ShowMask = true;
            mapButton.AjaxEvents.Click.EventMask.Msg = "Einhängen";
            mapButton.AjaxEvents.Click.EventMask.MinDelay = 200;
            mapButton.AjaxEvents.Click.Success = "PutInFolder();";
            mapButton.ID = "MapButton";
            mapButton.Hidden = !update;

            tb.Items.Add(mapButton);


            deleteMapButton = new ToolbarButton();
            deleteMapButton.Icon = Icon.FolderDelete;
            deleteMapButton.AjaxEvents.Click.Before = "parent.window.StatusBar.showBusy();";
            deleteMapButton.Text = "Mappenzuordnung löschen";
            deleteMapButton.AjaxEvents.Click.Event += new ComponentAjaxEvent.AjaxEventHandler(this.Delete);
            deleteMapButton.AjaxEvents.Click.EventMask.ShowMask = true;
            deleteMapButton.AjaxEvents.Click.EventMask.Msg = "Löschen";
            deleteMapButton.AjaxEvents.Click.EventMask.MinDelay = 200;
            deleteMapButton.AjaxEvents.Click.ExtraParams.Add(new Coolite.Ext.Web.Parameter("ParentNodeID", "parent.window.ParentNodeID.getValue()", ParameterMode.Raw));
            deleteMapButton.AjaxEvents.Click.ExtraParams.Add(new Coolite.Ext.Web.Parameter("DocID", "parent.window.CurrentDocID.getValue()", ParameterMode.Raw));
            deleteMapButton.AjaxEvents.Click.Success = "RemoveFromFolder();";
            deleteMapButton.Hidden = !update;
            deleteMapButton.ID = "DeleteMapButton";

            tb.Items.Add(deleteMapButton);

            TemplatePanel.TopBar.Add(tb);
        }

Does anybody know where these errors come from?

Thanks,
Sharon

Hi Sharon,

It is very strange error 'Ext is not defined', as I understood it occurs during you are working with Coolite/Ext.
Can you attach full page with reproduces the error?

Difficult. The tree is build using another programm which I can't give to you. I would have to build another application.
