Terracotta Discussion Forums

Similarly to post http://forums.terracotta.org/forums/posts/list/1045.page for a JCheckBox, I am now trying to share a JTextField across clustered Terracotta client GUIs. I tried to use javax.swing.text.PlainDocument as the shared model defined in ROOT similar to how the JCheckBox sample worked, but I am stuck with errors arond javax.swing.text.AbstractDocument not being non-portable. I tried the Ecilpse built-in "helper" features of the debugger to attempt to add locks and so on, but I cannot get it working.

Anyone has sample code for this? I am building a PoC and want to showcase this. I know that my issue is Swing lack of knowledge, but I cannot help that right now. :)

Thanks,

Instead of turning PlainDocument as root, which would drag an entire tree of classes with it (including classes that might not be TC portable at all/yet) it would be simpler in this case if create your own application's model that could be observed or that could send out notifications to update the model that your view uses.

I would suggest looking at the sample application generated by the pojo archetype http://forge.terracotta.org/releases/projects/pojo-archetype to accomplish this.

You will need to have Maven 2.0 installed - I've attached an archive of the sample app.

Find attached an update to the CheckBoxTest Eclipse project that adds a new TextField sample that adapts the TextField's document to a SharedString that is shared.

Thanks for the replies and examples. I understand some of my choices now!
