[news.eclipse.modeling.gmf] Re: Change Popup Strings and Icons in Mindma

[kojihashi@xxxxxxxxx (Koji Hashimoto)]

Joe,

Please forget the previous tricky solution.

You can prevent from overwriting your custom extension by changing 
plugin.xml in the diagram project 
from:
<?gmfgen generated="true"?>
to:
<?gmfgen generated="false"?>

BTW, GMF 2.0 generates plugin.xml in such a way that the "name" attribute 
of ElementType is externalized in plugin.properties, which is not 
overwritten by re-generating diagram code.
