CloverDX Designer application starts as two processes: CloverDX Designer GUI and CloverDX Runtime. These processes need to communicate with each other over TCP protocol. You should allow the mutual communication with Allow access button.


Designer Stops Responding

Due to bug in Linux/GTK+, Designer runs out of number of open files as the backend opens the file /etc/cups/client.cont many times.

As workaround, you can configure the printers in /etc/cups/client.conf file, or add -Dorg.eclipse.swt.internal.gtk.disablePrinting to CloverDX.ini file. See, or

Welcome Page not Displayed

Welcome page requires webkitgtk library to be present on your system. Install webkitgtk version 1.


Hints on Edges Have no Content

If hints on edges contain only the frame but no content, you should install webkitgtk.



If you use CloverDX Designer with Subclipse plugin, and perform the following steps: In a project, create a directory aaa, create a file bbb, delete the directory aaa, and rename file bbb to aaa; you may encounter the message:

An exception has been caught while processing the refactoring 'Rename resource'.
Problems encountered while moving resources.

Error deleting markers for resource bbb.
Resource aaa does not exist.

This problem is caused by caching resources by the Subclipse plugin an has nothing to do with CloverDX.

If this message appears, refresh the project in Navigator.
