Back to the tutorial. I have created ther perspective stack/partsashcontainer/part stack. When I add the part I get the error below.

Is this a bug or is it something strange with the various install and updates I have done to my installation. If it is a bug do I just log it in bugzilla.

It does not stop the app launching but I can't put labels etc on the part as it won't render in the editor.

java.vendor=Sun Microsystems Inc.

Ah well as I can't now attach Java code to the model my tutorial has come to a premature end. Do you know the bugzilla number so I can watch it to see when I can go back to playing. If not I will go search for it.

Works for me, can you add the class by entering the bundleclass URI directly?

The URI schema is described here: URI schema in Eclipse 4

I added a Part to the PartStack.
<children xsi:type="basic:PartSashContainer" xmi:id="_MDPXAE5mEeG5SvA2hAKwLg" elementId="sash" horizontal="true">
<children xsi:type="basic:PartStack" xmi:id="_NDeE8E5mEeG5SvA2hAKwLg" elementId="one">
<children xsi:type="basic:Part" xmi:id="_0t2IcE5mEeG5SvA2hAKwLg"/>
</children>
When I click on the Part in the Form tab in the model editor I get the error and the Part form does not render. The title changes from PartStack to Part but the rest of the form stays as the PartStack form. Hence I can't set the values for the Part as I cannot get the form to render.
