How to replace currently displayed diagram with another diagram [message #1718294]

Hi,

I wrote my own multipage editor which lets users choose between a source view and a design view. The design view shows the diagram and the source view displays the XML source of the model.

When I change my source I want to update the diagram with all the changes from the source editor. What would be the best / cleanest way to do it? Is it possible to hot swap diagram objects in the diagram editor somehow? (not sure if that matters, but I am not using EMF but a pojo model)

Thanks for any pointers,
Lars

Lars,

you can call the method refresh on the DiagramBehavior instance of your diagram editor, that will update the complete diagram. However, depending on what happened in the text file, this might lead to exceptions because the source might not be in a consistant state.

Hi Michael,

that only works if all your changes are directly propagated into the text file, right? (means saved before creating the diagram)
In my case I do the changes in the source editor and those are not yet saved when loading it into the diagram. (kind of a round trip editor)
