Cut and Paste in JavaAplet mode

Has anyone implemented cut and paste in JavaAplet mode? I get a java.security.Access.ControlException(access denied) whenever I call any DiagramView method that uses the clipboard.
Thanks

Try using the copySelection and pasteSelection methods of the Diagram class. This won't save the items in the Windows clipboard, but will return an object that contains the cloned items which you could keep in some JS variable on the page.

If you have a digital certificate, you could sign the applet and the clipboard functions should work too.

While researching this, we found Java supports some kind of "local" clipboards, independent from the system clipboard. Our developer will check if using local clipboard works without additional security permissions.

We have added clipboard methods to the DiagramApplet class. They use a local clipboard and aren't subjects to security checks:
https://mindfusion.eu/_beta/applet_clipbrd.zip

Code
Select All
var applet = <%= diagramView.AppletElement %>;
applet.copyToClipboard();
applet.pasteFromClipboard(10, 10);


I hope that helps,
Stoyan
