Dear Captain,

in a MultipleInstances - workplace - scenario, which ID can be used for a newly created workpage to inform about the creator?

We want give back information from the created workpage (only) to the creator.

Something like param 'wid':
Code:

 IWorkpageDispatcher wpd = (IWorkpageDispatcher) getOwningDispatcher().getTopOwner();
 			IWorkpageContainer wpc = getWorkpageContainer();
 			WorkpageStartInfo wpsi = new WorkpageStartInfo();
 			wpsi.setJspPage(EclntConstants.REL_JSP_PATH + EclntConstants.JSP_AUFTRAG_DATEN);
 			wpsi.setId(EclntConstants.WORKPAGE_ID);
 			wpsi.setText("Auftragsdaten");
 			wpsi.setOpenMultipleInstances(false);
 			wpsi.setDecorated(false);
 			wpsi.setImage("/images/workplaceicons/application_form_edit.png");
 			wpsi.setOpenAsPopupByDefault(true);
 
 			if (withData && selectedItem != null) {
 				wpsi.setParam("aid", "" + selectedItem.getAuftragId());
 				wpsi.setParam("asid", "" + selectedItem.getAuftragsschrittId());
 				wpsi.setParam("asrid", "" + selectedItem.getAuftragsschrittRessourceId());
 				wpsi.setParam("wid", getWorkpage().getId());
 			}
 			workpage = WorkpageStarterFactory.getWorkpageStarter().startWorkpage(wpd, wpc, wpsi);

But wid is only the JSP name.

Hi,

in principal we like the approach that workpages are quite isolated from one another - and they are startable by simple string-configuration (WorkpageStartInfo can be XML-ed as string). If workpages want to update one another then the preferred way is to do so by workpage-messaging.

What we do not "totally" like is that one workpage e.g. directly knows its caller by pointer instance. THen there is a modularization problem on the one hand and a garbage collection problem on the other hand (e.g. if calling workpage is closed).

Please take a look at workplace eventing.

Thanks! Björn
