Use the IPolicyTargetLayoutComposite's add methods to add State Policies aware UI controls. These methods take a PolicyActionContainer object as their final parameter. This ensures that a StateChangeTarget is added to the PolicyActionContainer for each UI control that is added to the composite

If you are Creating a State Policy aware dialog, use the IPolicyTargetLayoutComposite in the createDialogContent method. Otherwise, use the PolicyTargetCompositeFactory to get an IPolicyTargetLayoutComposite instance.

final PolicyActionContainer myPolicyContainer = addPolicyActionContainer("myPolicyContainer"); //$NON-NLS-1$

// Create a grid layout composite
final IEpLayoutComposite gridLayoutComposite =
        CompositeFactory.createGridWrapLayoutComposite(parent, 2, false);

// Wrap it in a State Policy aware layout composite
final IPolicyTargetLayoutComposite policyComposite =
        PolicyTargetCompositeFactory.wrapLayoutComposite(gridLayoutComposite);

// Add UI controls
policyComposite.addLabelBoldRequired("Label", labelData, myPolicyContainer);
policyComposite.addTextField(fieldData, myPolicyContainer);
