# Property Resolver

###### Identifier:

org.eclipse.jst.jsf.core.propertyresolver

###### Since:

1.5

###### Description:

Allows a third-party to define an alternative instance of the design time property resolver. This id can then be set on a project using DesignTimeApplicationManager.setPropertyResolverProvider. Once set on a project this id will be used to load the active design time property resolver.

- id - The id to be used to identify this property resolver.
- class - The class implementing the property resolver.
- forRuntimeClass - Names a class (it need not be on the class path at designtime) that this designtime property resolver is intended to shadow. The instance of AbstractDTPropertyResolver provided by the 'class' attribute _must_ implement the IDecorativeResolver tagging interface in order to be used in this way.
- instancePerProject - Default if not specified is false. This is backward compatible with pre-3.0 behaviour for the propertyresolver extension point. If set to false (or not set) a single instance of the property resolver will be used for all design time managers in the workspace. If set to true, a new instance will be created on every time this property resolver becomes the active one on a design time application manager. If 'class' specifies a type that implements org.eclipse.jst.jsf.designtime.el.IInstancePerProjectResolver, then setProject will be called with the host project. Implementing this interface is optional.

###### Examples:

The following example defines a new property resolver implemented by CustomDTPropertyResolver

       <extension
             point="org.eclipse.jst.jsf.designtime.propertyresolver">
          <propertyresolver
                class="org.eclipse.jst.jsf.dtresolver.test.resolvers.CustomDTPropertyResolver"
                id="org.eclipse.jst.jsf.dtresolver.test.propertyresolver2"/>
       </extension>
