Hi g_rathod,
I have a similar problem trying to use a custom Evaluator for a custom action.

1) Have you tried to

public class ClmsDraftBasedEvaluator implements ActionEvaluator‍

instead of

public class ClmsDraftBasedEvaluator extends BaseEvaluator‍

?

2) Have you any interesting log message in alfresco.log?

[…]

2) slingshot-documentlibrary-context.xml

 <bean id="evaluator.doclib.action.customDraftBased" class="com.clms.web.evaluator.CustomDraftBasedEvaluator" />‍

3) CustomDraftBasedEvaluator.java

public class ClmsDraftBasedEvaluator extends BaseEvaluator {

   @Override
   public boolean evaluate(JSONObject jsonObject) {
      System.out.println("*** JSONObject  ::" + jsonObject);
      return true;
   }

}‍‍‍‍‍‍‍‍‍

btw I believe that the attribute class of your bean should match the class name.
You used ClmsDraftBasedEvaluator as evaluator class name and CustomDraftBasedEvaluator as class name reference in your bean. Could you check if you have an exception caused by Spring during startup (alfresco.log)?

Hi acarpine,

Thanks for your reply,

Sorry it was typo actually it is "CustomDraftBasedEvaluator" instead "ClmsDraftBasedEvaluator".
and using evaluator As I have observed out of box things they have extending BaseEvaluator everywhere instead "ActionEvaluator".

I will try with your given approach and check again.
Did you able to get your custom evaluator? actually I need to check with specific type of space only show my custom action, out of box they had given for aspect.

any clue will be fine.

Thanks,

I was able to define my custom evaluator in Alfresco Explorer but I'm not able to use it in Alfresco Share.
Seem that the Spring bean is not correctly loaded at startup time (so the Evaluator is not loaded)…but I can't figure out what I'm missing…

I believe you have a slightly different issue because you don't see any exception in the alfresco.log, anyway
in case of any progress I will let you know

Hi acarpine,

Even I have same issue, I could not find my evaluator "evaluator.doclib.action.customDraftBased"
my tomcat log says :
2012-03-12 11:54:16,906 WARN [web.scripts.ActionEvaluatorHelper] [http-8080-26] Evaluator 'evaluator.doclib.action.customDraftBased' not found.

What I need to achieve is like below :
- Where ever in document library, I have clmraft type folder I need to show one extra custom action of workflow.
Currently I can see that action to every folders instead specific type of folder ..
this way my Evaluator not working.

Anyone have achieved like this in alfresco share 4?

Ops…I believe that my goal is different from yours because I'm trying to use a "new" evaluator
(a java class that implements an Alfresco evaluator). You solved the problem just using a specific
configuration for an Alfresco evaluator.

Anyway good job g_rathod 🙂

Hi acarpine,

You are right, for simple type check this solution works, but when we need to check some more advance conditions we need our evaluator extending BaseEvaluator.
I already tried creating new evaluator by extending BaseEvaluator, but somehow that class is not loading at all.
Even though my jar file contains that class, bean is not identifying that class and throws an exception for ClassNotFound.

Hi acarpine,

I can run my custom evaluator class (my new java class) , for that its important you copy your webapps/alfresco/WEB-INF/lib jar file to share/WEB-INF/lib.

How can we get NodeRef on which evaluator is written? any idea? we have jsonObject which gives here type, but for NodeRef need to check deeply.
