why save failed [message #677676]

hi,

I use GMF to develope a modeling tool,
i got a trouble that when i adjust the connection Anchor,from p1 index.php/fa/2980/0/

to p2

by set the sourceAnchor and targetAnchor

			EllipseAnchor sourceAnchor = new EllipseAnchor((IFigure)sep.getFigure());
			EllipseAnchor targetAnchor = new EllipseAnchor((IFigure)tep.getFigure());
			connectionEditpart.getConnectionFigure().setSourceAnchor(sourceAnchor);
			connectionEditpart.getConnectionFigure().setTargetAnchor(targetAnchor);

it seems worked,but when i save and close the diagram and reopen it,it still not changed(as p1),
i examed the diagram file with UltraEdit,i see it has not been changed

so,why it obviously changed successfully in the canvas,but in the file,it was not changed at all?
(i tried 2 ways to save ,but it does'not work:
1 currentDiagramEditor.doSave
2 ctrl+s in the editer UI
and i failed)

thanks.

Hi,

If you modify directly the figures, there state is not persisted in the diagram file. You have to use a SetConnectionAnchorCommand to perform this operation. It will apply changes on both diagram editor and underlying diagram model.

thank you,Mickael.

um.."there state is not persisted in the diagram file",thanks for advice and it seems accurate and right.
but,when I tried to use "SetConnectionAnchorCommand" ,i found seems there is no such method or "ChangeConnectionAnchorCommand" in this framework

then i think maybe I should use "ChangePropertyValueRequest" but it seems it can change some infomation but not ConnectionAnchor,so I am confused again.

Sorry, I should have written SetConnectionAnchorsCommand (with a S after Anchor).
