		selectedChild = child.getContents().get(selectedChildIndex);
		child.getContents().remove(selectedChild);
	}

Quelqu'un aurait il une idée de ce qui provoque ce résultat

Bonjour

La liste child.getContents() est vide.

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
3
4
5
Caused by: org.eclipse.emf.common.util.BasicEList$BasicIndexOutOfBoundsException: index=0, size=0
	at org.eclipse.emf.common.util.BasicEList.get(BasicEList.java:535)
	at com.odcgroup.page.ui.figure.AbstractHeaderFigure.getIndexOfSelectedItem(AbstractHeaderFigure.java:99)
	at com.odcgroup.page.ui.figure.AbstractHeaderFigure.paintSpecificFigure(AbstractHeaderFigure.java:243)

Donc, c'est cette ligne qui plante :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

selectedChild = child.getContents().get(selectedChildIndex);

hello,

en fait l'erreur provenait d une autre méthode mais c était bel et bien un child.getContents().get(index) qui plantait
