HI,

while generating gmf codes i got the flowing error in the ApplicationVisualIDRegistry, i tried to modify the template
instead of:

Quote:

switch (containerVisualID) {
case HtmlGM.diagram.edit.parts.PageEditPart.VISUAL_ID:
if (HtmlGM.HtmlGMPackage.eINSTANCE.getHtml().isSuperTypeOf(
domainElement.eClass())) {
return HtmlGM.diagram.edit.parts.ApplicationEditPart.VISUAL_ID;
}

i try to have something like:

Quote:

switch (containerVisualID) {
case HtmlGM.diagram.edit.parts.PageEditPart.VISUAL_ID:
return getViewChildrenForApplicationEditPart(domainElement);
}

and to have this method defined outside

Quote:

private static int getViewChildrenForApplicationEditPart(EObject domainElement) {
if (HtmlGM.HtmlGMPackage.eINSTANCE.getHtml().isSuperTypeOf(
domainElement.eClass()))
return HtmlGM.diagram.edit.parts.ApplicationEditPart.VISUAL_ID;
return -1;
}

so i change the template :

Quote:

«DEFINE genAllMethodNodeCase FOR gmfgen::GenDiagram»
«EXPAND caseMethod FOREACH getAllContainers()-»
«ENDDEFINE»

«DEFINE caseMethod FOR gmfgen::GenContainerBase-»
«EXPAND caseMethodNodeNode FOREACH getContainedSemanticNodes(self)-»
«ENDDEFINE»
«DEFINE caseMethodNodeNode FOR gmfgen::GenCommonBase»
private static int getViewChildrenFor«self.editPartClassName»«e»(org.eclips e.emf.ecore.EObject domainElement){
if («EXPAND checkSemanticElement»)return «EXPAND visualID»;
return -1;
}
«ENDDEFINE»

but it genarete several method with the same name giving the following error:

Quote:

Duplicate method getViewChildrenApplicationEditPart(EObject) in type ApplicationVisualIDRegistry

any ideas how i could solve this problem

thanks

Hi,

you are calling caseMethodNodeNode with a FOREACH.
That is why there are several times the same method.

Hello,

The problem is not that you are calling that NodeNode expand FOREACH, thats correct.

The problem is that your method name does not depend on the pair <parent, child> but only on <child>, so if you have PopularChildEditPart as a possible child for 2 different parents, you will get 2 identically named methods.

You may solve this by collecting all the children into the set, or (a bit ugly, but should work) just by generating 1 method for every pair:

«DEFINE caseMethod FOR gmfgen::GenContainerBase-»
«EXPAND caseMethodNodeNode(self) FOREACH getContainedSemanticNodes(self)-»
«ENDDEFINE»
«DEFINE caseMethodNodeNode(parent : gmfgen::GenCommonBase) FOR gmfgen::GenCommonBase»
private static int getViewChildrenForParent«parent.editPartClassName»OfType«self.editPartClassName»(org.eclips e.emf.ecore.EObject domainElement){
if («EXPAND checkSemanticElement»)return «EXPAND visualID»;
return -1;
}
«ENDDEFINE»
