I have one business object and I was linked two Pictogram Elements with it.
When I want to remove one of Pictogram elements I need to unlink it with business object. Because if don't unlink business object with pictogram then removed all pictograms which was linked with business object.
How I can unlik PictogramElement s with Business object.

Sorry for my English.

For Example:

public class AddFeature extends AbstractAddFeature {

public PictogramElement add(IAddContext context){
Object bo = getBusinessObject();
PictogramElement peFirst = getFirstPictogram();
PictogramElement peSecond = getSecondPictogram();
link(peFirst, bo);
link(peSecond, bo);
}// add
}// Add Feature

public class RemoveFeature implements IRemoveFeature{
void remove(IRemoveContext context){
Object bo = getBusinessObject();
PictogramElement peFirst = getFirstPictogram();
PictogramElement peSecond = getSecondPictogram();

/*In this part i want to delete peFirst*/
/*But first I need to UNLIK*/

//unlink code
/*Delete PictogramElement*/
Graphiti.getPeService().deletePictogramElement(peFirst);
}//void remove
}//RemoveFeature

Anatoliy,

the method AbstractFeature.link(PictogramElement, Object[]) (note the array
second parameter) will remove all currently linked domain objects and link
only the new ones passed into the method. Probably that's what you're
looking for.
