For a Commerce Manager dialog to be State Policies aware, it must extend AbstractPolicyAwareDialog and implement ObjectGuidReceiver.

The dialog must also have a zero-parameter constructor and must be able to perform all persistence operations (retrieve, update, save, etc.) by itself.

The following methods must be implemented:

• getTargetIdentifier
• setObjectGuid
• createDialogContent
• getOkButtonPolicyActionContainer
• refreshLayout

getTargetIdentifier must return the unique identifier that will be used to map Creating a State Policy Contribution to this object.

         com.elasticpath.cmclient.catalog/src/main/java/com/elasticpath/cmclient/catalog/dialogs/catalog/VirtualCatalogDialog.java
	public String getTargetIdentifier() {
		if (this.virtualCatalog.isPersisted()) {
			return "virtualCatalogDialogTarget"; //$NON-NLS-1$
		}
		return "virualCatalogDialogEditableTarget"; //$NON-NLS-1$
	}
      
Copy

setObjectGuid must be implemented to retrieve the dialog's dependent object from its GUID.

         com.elasticpath.cmclient.catalog/src/main/java/com/elasticpath/cmclient/catalog/dialogs/catalog/VirtualCatalogDialog.java
public void setObjectGuid(final String objectGuid) {
	if (objectGuid == null) {
		virtualCatalog = getBeanFactory().getBean(ContextIdNames.CATALOG);
		virtualCatalog.setMaster(false);
	} else {
		virtualCatalog = catalogService.findByCode(objectGuid);
		if (virtualCatalog == null) {
			throw new IllegalArgumentException(
					NLS.bind(CoreMessages.Given_Object_Not_Exist, new String[] {"Virtual Catalog", objectGuid})); //$NON-NLS-1$
		}
	}
}

createDialogContent is responsible for creating and laying out the dialog's UI controls. The first step is usually to add a Policy Action Container. Then use the IPolicyTargetLayoutComposite's add methods to add UI controls. These methods take the PolicyActionContainer object as their final argument. This ensures that a StateChangeTarget is added to the PolicyActionContainer for each UI control that is added to the dialog.

         com.elasticpath.cmclient.catalog/src/main/java/com/elasticpath/cmclient/catalog/dialogs/catalog/VirtualCatalogDialog.java
protected void createDialogContent(final IPolicyTargetLayoutComposite dialogComposite) {
	
	// This name does not need to match anything necessarily
	readOnlyVirtualCatalogPolicyContainer = addPolicyActionContainer("readOnlyVirtualCatalogDialog"); //$NON-NLS-1$
	editableVirtualCatalogPolicyContainer = addPolicyActionContainer("virtualCatalogDialog"); //$NON-NLS-1$
	
	mainPolicyComposite = dialogComposite
			.addGridLayoutComposite(2, false, dialogComposite
					.createLayoutData(IEpLayoutData.FILL, IEpLayoutData.BEGINNING, true, false),
									  editableVirtualCatalogPolicyContainer);
 
	final IEpLayoutData mainCompositeFieldData = mainPolicyComposite
			.createLayoutData(IEpLayoutData.FILL, IEpLayoutData.BEGINNING, true, true);
	final IEpLayoutData mainCompositeLabelData = mainPolicyComposite
			.createLayoutData(IEpLayoutData.BEGINNING, IEpLayoutData.BEGINNING, false, true);
 
	if (isVirtualCatalogPersistent()) {
		mainPolicyComposite.addLabelBold(CatalogMessages.CatalogSummarySection_CatalogCode,
				                         mainCompositeLabelData, readOnlyVirtualCatalogPolicyContainer);
		
		this.catalogCode = mainPolicyComposite.addTextField(mainCompositeFieldData, readOnlyVirtualCatalogPolicyContainer);
	} else {
		mainPolicyComposite.addLabelBoldRequired(CatalogMessages.CatalogSummarySection_CatalogCode,
												 mainCompositeLabelData, editableVirtualCatalogPolicyContainer);
		this.catalogCode = mainPolicyComposite.addTextField(mainCompositeFieldData, editableVirtualCatalogPolicyContainer);
	}

getOkButtonPolicyActionContainer returns the Policy Action Container that will control the state of the dialog's OK or Save button.

         com.elasticpath.cmclient.catalog/src/main/java/com/elasticpath/cmclient/catalog/dialogs/catalog/VirtualCatalogDialog.java
protected PolicyActionContainer getOkButtonPolicyActionContainer() {
	return this.editableVirtualCatalogPolicyContainer;

refreshLayout can be implemented to refresh the layout of parent composites if required.

         com.elasticpath.cmclient.catalog/src/main/java/com/elasticpath/cmclient/catalog/dialogs/catalog/VirtualCatalogDialog.java
protected void refreshLayout() {
	if (mainPolicyComposite != null) {
		mainPolicyComposite.getSwtComposite().layout();
		mainPolicyComposite.getSwtComposite().getParent().layout();
	}
}
