John,

This seems to be a general Eclipse UI extension questions that I know
nothing about. maybe someone on the platform newsgroup would have some
ideas, so I've added it to the "to" list of this reply.

Managed to get this working by using the propertyTester extension.

This seems to be a long way to do this and possibly even the wrong way -
but it works!

<extension point="org.eclipse.core.expressions.propertyTesters">
<propertyTester
class="myClass.ModelPropertyTester"
id="myID.propertyTester"
namespace="myNameSpace.properties"
properties="isModel"
type="java.lang.Object">
</propertyTester>
</extension>

<extension point="org.eclipse.ui.propertyPages">
...
<enabledWhen>
<test
forcePluginActivation="true"
property="myNameSpace.isModel"
value="true">
</test>
</enabledWhen>
...
</extension>

code in "myClass.ModelPropertyTester"
public class ModelPropertyTester extends PropertyTester {

public boolean test(Object receiver,
String property,
Object[] args,
Object expectedValue) {

boolean result = false;

if (property.equalsIgnoreCase("isModel")){

if(receiver instanceof ModelServerElement){

ModelServerElement modelServerElement =
(ModelServerElement)receiver;

if (modelServerElement.getElement() instanceof Model) {
result = true;
}

}

}

return result;
}
}

I'm not sure why it works, but it doesn't look like it should. You define:
namespace="myNameSpace.properties"
properties="isModel"

and then use it as:
property="myNameSpace.isModel"

except your property tester is myNameSpace.properties.isModel
