Hey
I am using the GWT Designer downloaded from the latest Update Site for
Eclipse 3.6.
I seem to be unable to add any of the TextBox Controls (TextBox,
TextArea, PasswordTextBox) those inheriting from TextBoxBase from the
Palette. Clicking on any of these generates the following error in the
Designer Editor Erros
Palette: can not load component com.google.gwt.user.client.ui.TextArea
Stack trace:

I have tried installing GWT on another linux machine with a similar
configuration and simalr eclipse settings and encounter exactly the
same error.
Another user seems to have encountered a similar error here:

Thanks for throwing any light on this issue,
