Help Required on WDK Preconditions

aromal_b

Hello Experts,

I am new to WDK. I managed to create a custom menu item with the help of WDK Tutorial.
Now I trying to make a menu Item visible only when the selected document is checked out. I am trying to do this preconditions.
However, I am getting Error below error from the prevalidation class when logging into webtop. I am unable to fix it. Can someone please help?

Error

Action Service - unable to instantiate qualifier class: com.ford.custom.PrivilegedCancelCheckoutPreCondition
class java.lang.InstantiationException

==========================================================================

My Action XML
=====================

<config version = "1.0">
<scope type="dm_sysobject">

My PreCondition Class:
public abstract class PrivilegedCancelCheckoutPreCondition implements IActionPrecondition

{
final private static String m_strRequiredParams[] = new String[] {"objectId", "lockOwner"};
String[] getRequiredParams()
{
  System.out.println("************ INto the getRequiredParams...");
  return m_strRequiredParams;
}

public boolean queryExecute(String strAction, IConfigElement config, ArgumentList arg, Context context, Component component)
{
  boolean execute = false;
  try
  {
   //get object ID  
   String objId = arg.get("objectId");
   String strLockOwner = arg.get("lockOwner");  
   if ( strLockOwner == null || strLockOwner.length() == 0 )
    { 
    execute = true; 
    }  
  }
  catch(Exception de)
  {

  }
  return execute;  
  }

Thanks a lot!!.

For some reason Eclipse was throwing error on removing the abstract keyword.
As per your suggestion I removed the abstract keyword and changed the queryExecute parameter from

public boolean queryExecute(String strAction, IConfigElement config, ArgumentList arg, Context context, Component component)

to

public boolean queryExecute(String strAction, com.documentum.web.formext.config.IConfigElement config, com.documentum.web.common.ArgumentList arg, com.documentum.web.formext.config.Context context, Component component)

ie. with the package details and it worked fine.

Thanks again.

Looks like you have some class named IConfigElement, ArgumentList or Context in the same package as your precondition.
