SWT Designer View will not open.

I tried to open a sample Java file the SWT Designer Multi-Page Editor as described in the installation doc. The Icon shown on the editor tab is correct but there is now graphical UI to add or manipulate SWT components.

In the eclipse log file seems to be a hint on the error:

java.lang.NullPointerException

Can you send this sample file to support@swt-designer.com ?

[admin]

I think, that you pressed on test button on toolbar.
This button should be used only after you select method on "Design" page.
To edit design in GUI switch to "Design" page and then use drag and drop from control palette.

We will fix this bug in next build.

The sample is running well.
I constructed it as a table example with the your wizard. The problem is somehow connected to the eclipse environment.
My Problem is that the GUI for SWT Components is not visible.

Thanks for your answer in advance

It works now...
though it would be helpful if you mark the second tab of the designer - that is what i hadn't seen so far - with a yellow sign as you did in the swt-designer.pdf (page2) for all other elements of your designer.

Thanks a lot.
