Hi,
I want to update palette dynamically. i have certain set of libraries and user can add or delete libraries from another dialog, based on libraries added/deleted, i want to show nodes on palette. Please let me know if i can update palette at runtime.
Thanks In advance.

Thanks and Regards
Mohit Advani

Hi,

This is not supported (see https://bugs.eclipse.org/bugs/show_bug.cgi?id=442145). The tools on the palette of a Sirius diagram are not just elements "prototypes" that are copied/instanciated on the diagram, they are tools defined statically in the odesign model, with possibly complex behavior. Adding new tools dynamically would imply modifying the odesign being used to add the tool definitions, but modifying the modeler's definition in this way is not supported.

Depending on your context, one possible workaround is to define *one* tool in your odesign which invokes some Java code that displays through an SWT/JFace dialog the list of possible libraries (computed dynamically by your code), and then add the one selected.

Regards,
Pierre-Charles David

Thanks for your quick reply, can i statically create all nodes initially and later based on some condition (via service method call) hide or disable it.

You can add all tools and then show/hide them with a filter a) per tool or b) via the new toolfilter extension mechanism, see https://bugs.eclipse.org/bugs/show_bug.cgi?id=549558
