Error While Using Chain Of Command Invalid Token 'next'

Posted on by Community Member

I override the canSubmitToWorflow() of salesTable, but the workflow should get activated only for the specified conditions. For that I was trying to create a chain of command method the code used is below,

Thanks.

    1) Your class must be decorated with [ExtensionOf(formStr(SalesTable))] and be declared as final.

    2) You can't set default values for CoC method parameters

    3) Your next call must include all parameters of the standard method

    Thanks for your reply Nikolaos,

    Code of the extension class is as below,

    [ExtensionOf(tableStr(SalesTable))]

    final class SalesTable_Extension

    {

       public boolean canSubmitToWorkflow(str _workflowType = '')

       {

           boolean ret = false;

           ret = next canSubmitToWorkflow(_workflowType);

           if (this.RecId && this.DocumentWorkflowState == DocumentWorkflowState::NotSubmitted)

           {

               ret = true;

           }

           return ret;

       }

    I didn't understand point number 2. It that means I can't write this line

    ret = next canSubmitToWorkflow(_workflowType); ??

    Point 2 means that your own method should look like this:

    public boolean canSubmitToWorkflow(str _workflowType) <- no default value

    Also, table SalesTable doesn't include method canSubmitToWorkflow (at least in 7.3), instead form SalesTable does include that. So you must extend the form SalesTable, not table SalesTable. Also, I would not name my class SalesTable_Extension, because naming conflicts are likely to occur. Instead include your three letter prefix in the object name. For example ABCSalesTable_Extension.

    table SalesTable doesn't include method canSubmitToWorkflow -- I have overridden it using overlayering. As using extension and  defining this method it is not allowing to enable workflow for sales order.

    Form SalesTable does not contain this method, This is a standard method of table which must be overridden in order to enable workflow.

    I have not followed the best practices, I was trying to achieve this in a demo environment.

    Thanks.
