             This element is used to evaluate the property state of the object in focus. The set of testable properties can be extended using the &lt;b&gt;org.eclipse.core.expressions.propertyTesters&lt;/b&gt; extension point. The test expression returns EvaluationResult.NOT_LOADED if the property tester doing the actual testing isn&apos;t loaded yet and the attribute forcePluginActivation is set to false.  If forcePluginActivation is set to true and the evaluation context used to evaluate this expression support plug-in activation then evaluating the property will result in activating the plug-in defining the tester.

                   is a boolean property (value will be Boolean.TRUE). The test expression is supposed to return
 EvaluationResult.TRUE if the property matches the value and EvaluationResult.FALSE
 otherwise. The value attribute is converted into a Java base type using the following

  &lt;li&gt;the string &amp;quot;false&amp;quot; is converted into Boolean.FALSE&lt;/li&gt;

  converts the value into an Integer object.&lt;/li&gt;

  &lt;li&gt;the conversion of the string into a Boolean, Float, or Integer can
  be suppressed by surrounding the string with single quotes. For
  example, the attribute value=&amp;quot;&apos;true&apos;&amp;quot; is converted into the
