Custom Action Evaluator

[mangar]

I am having a problem with a custom evaluator.  I have an action in my share-config-custom.xml:

      <action id="sammy.actions.writeToLog"
              icon="log_write"
              type="javascript"
              label="actions.sammy.writeToLog">
         <param name="function">onActionSimpleRepoAction</param>
         <param name="successMessage">message.writeToLog.success</param>
         <param name="failureMessage">message.WriteToLog.failure</param>
         <evaluator negate="true">sammy.writeToLog.Evaluator</evaluator> 
      </action>‍‍‍‍‍‍‍‍‍

in my custom-slingshot-application-context.xml I have a simple one liner bean declaration:

<bean id="sammy.writeToLog.Evaluator" class="com.sammy.share.action.evaluator.LogWriteEvaluator">
</bean>‍‍

and in my jar file located in share/WEB-INF/lib I have this:

public class LogWriteEvaluator extends BaseEvaluator {

    @Override
   public boolean evaluate(JSONObject jsonObject) {
          return true;
   }
    
}‍‍‍‍‍‍‍‍

if I comment out the evaluator in the action declaration, It shows up fine, so I know that works.

what am I missing?

The evaluator always returns true. However, in your use of the evaluator you negate the output by using the attribute

negate="true"‍

. This means that the output of the evaluator is inverted. Therefore, true = false and the action doesn't show.

If you make the evaluator return false, or leave out the negate attribute or set it to false, the action should show up.

Hi,

  I have also tried for making a custom evaluator so that it should restrict the articular action in share for nly some folders. I have explained the error in the below text file.

Please help me with this.

Thanks in advance.

Try moving your JAR to $TOMCAT_HOME/webapps/share/WEB-INF/lib instead of using $TOMCAT_HOME/shared/lib.

Thanks for your time jpotts!! But my jar is there only in tomcat\webapps\share\WEB-INF\lib… and i have all the required jars in buildpath of eclipse and those are present here also in the same path…I dn't understand where i went wrong.

Thanks in advance.

From my understanding the evaluator class you created is not there in your JAR, make sure your build was successful and contains this class.

Hi mani,

   Thanks for your reply. That is what i am not understanding. Actually i have this java class in share jar in package as "org.alfresco.web.evaluator.doclib.action". And i have build this jar and placed it in "C:\tmcat\Webaps\share\WEB-INF\lib". I don't know where i am wrong.

Thanks in advance,
