Try calling IEvaluationService.requestEvaluation(propName);

this error:

Discouraged access: The method requestEvaluation(String) from the type EvaluationService is not accessible due to restriction on required library C:\Java\eclipse-rcp\eclipse\plugins\org.eclipse.ui.workbench_3.6.0.I20100603-1100.jar

i'm doing new EvaluationService().requestEvaluation("export");

... which is not what Prakash recommended. All services should
be required by a corresponding service locator. One way
of realizing this is to use HandlerUtil to retrieve from the
command execution event the active workbench window and use
it as a service locator for IEvaluationService.

oh sorry
it's working now
i've made a properytester:

<extension
         point="org.eclipse.core.expressions.propertyTesters">
      <propertyTester
            class="br.com.athus.tester.ExportTester"
            id="testerMenu"
            namespace="exportSucesso"
            properties="export"
            type="java.lang.Object">
      </propertyTester>
   </extension>

and if a single property is true, the menu appears, as i expected Very Happy

i've found the help here: http://dev.eclipse.org/newslists/news.eclipse.platform.rcp/m sg35998.html
