Hello Jun.
I tried to use createComponent in this way:
unitUsage = wdThis.wdGetGenericSHComponentUsage();
unitUsage.createComponent();
IExternalGenericSHInterface intrfcUM = (IExternalGenericSHInterface)unitUsage.getInterfaceController() .wdCastTo(IExternalGenericSHInterface.class);
IWDOVSContextNotificationListener listenerUM = intrfcUM.getListener(unitOVS);
WDValueServices.addOVSExtension(IPrivateIndexView.IIndexRecordElement.UNIT_MEASURE_TXT_SHORT, new IWDAttributeInfo[]{nodeIndInfo.getAttribute(IPrivateIndexView.IIndexRecordElement.UNIT_MEASURE_TXT_SHORT)}, intrfcUM.getInputNode(), intrfcUM.getOutputNode(), listenerUM);
IWDComponentUsage phdWrkKndUsage = wdThis.wdGetGenericSHComponentUsage();
phdWrkKndUsage.createComponent();
IExternalGenericSHInterface intrfc = (IExternalGenericSHInterface)phdWrkKndUsage.getInterfaceController() .wdCastTo(IExternalGenericSHInterface.class);
IWDOVSContextNotificationListener listener = intrfc.getListener(myOVSListener);
WDValueServices.addOVSExtension(IPrivateIndexView.IWorkKindsElement.WORK_KIND, new IWDAttributeInfo[]{phdWrkKndInfo.getAttribute(IPrivateIndexView.IWorkKindsElement.WORK_KIND)}, intrfc.getInputNode(), intrfc.getOutputNode(), listener);This method called everytime when ScreenView is called.
On the exit from ScreenView I try to delete usage:
if(phdWrkKndUsage != null){ phdWrkKndUsage.deleteComponent();
}
if(unitUsage != null){
unitUsage.deleteComponent();
}(phdWorkKndUsage and unitUsage are attributes of the ScreenView Comp Controller).
When I try to call ScreenView I'm faced with this exception:
ComponentUsage(com.acme.view.indexes.wd.comp.indexview.IndexView:GenericSH, createOnDemand=false, childComponent=com.acme.wd.searches.comps.genericsh.GenericSH): No active component must exist when creating a component.
This exception throwed at the line with phdWrkKndUsage.createComponent();
Thanks and regards
Lev
