TypeError: this.removeAt is not a function

[paco]

Hello,

I take the "Master Detail" sample from the Showcase and added a Delete button. The sample uses client only datasource and data is feed with setTestData(...). When I press the delete button I got following exception:

Uncaught JavaScript exception [this.removeAt is not a function] in http://127.0.0.1:8888/test/sc/modules/ISC_Grids.js, line 45

and following error in the development console:

I'm using SmartGWT Pro 2.4.

Is this some BUG ? Can I do some workaround ?

Best Regards,

I forgot to post my delete button action:

  btnDelete.addClickHandler(new ClickHandler() {
      public void onClick(ClickEvent event) {
        if (listGrid.getSelection().length <= 0) {
          SC.warn("No itmes selected");
          return;
        }

        SC.ask("Delete", "Do you really want to delete ?", 
            new BooleanCallback() {
              public void execute(Boolean value) {
                if (! value) {
                  return;
                }

                listGrid.removeSelectedData();
              }
            });
      }
    });

Any thoughts ?

Best Regards

Hello,

I managed to find the problem. I did ListGrid initialization with setSaveLocally(true). After I removed this everything is working fine.

Best Regards
