[news.eclipse.modeling.gmf] Re: How to call own layoutProvider from "Arr

[Mariot Chauvin <mariot.chauvin@xxxxxxx>]

Hi Martin,

It seems to me that your class value in plugin.xml is not the right one :

<layoutProvider class="ui.diagram.providers.LayoutProvider">

should be :

<layoutProvider class="yourcompany.yourpackage.PscViewerLayoutProvider">

BTW debugging with system.out is evil :P, why you do not simply add breakpoints ?

Regards,

Mariot
