[Gambas-user] Two many objects and two many forms

[Bruce]

:-Q

I have a collection of objects, of two types, both of which inherit from
the same superclass, "ActionItem".  One is a query, i.e. an object
whose .CmdString is an SQL string; and the other is a command,
whose .CmdString is a Shell string.  IOW:
                           ActionItem
                                ^
                                |
                ________________________________________
                |                                      |
           ActionQuery                           ActionCommand

The only difference between ActionQuery and ActionCommand is they have
different code for the "Exec" method in each of them.  (That either
executes the query against the database on one hand and acts on the
results or Shells the command "To" and interprets the return. That bit
works fine.)

What I cant work out is this.

I have, by necessity, two editor forms that allow the user to configure
the "ActionItems" in the collection.  (They are both fairly similar
visually but have quite different internal code.) 
The user is presented with a list of the ActionItems in the main form
and can select one and activate it's editor.
        Public Sub mnuEditAction_Click()
        
          Dim fec As FEditCommand
          Dim feq As FEditQuery
          Dim wkform As Form
          Dim wkAction As CActionItem
          
          If lvwActionList.Current.Selected Then
            wkAction = $actions[lvwActionList.Key]
            If wkAction.ActionType = "Command" Then
              fec = New FEditCommand
              fec.ActionItem = wkAction
              wkform = fec
            Else
              feq = New FEditQuery
              feq.ActionItem = wkAction
              wkform = feq
            Endif
        
            If wkform.Run("Edit") Then            <---- FAILS HERE
              wkform.ActionItem.Save
              If wkform.ActionItem.Name = lvwActionList.Key Then
                $actions[lvwActionList.Key] = wkform.ActionItem
              Else
                $actions.Add(wkform.ActionItem, wkform.ActionItem.Name)
                $actions.Remove(lvwActionList.Key)
              Endif
              LoadActionList
            Endif
          Endif
        End
        
The code fails with "Unknown Symbol 'Run' in class 'Form'". But both
FEditCommand and FEditQuery have 
	Public Sub Run(Type As String) As Boolean
methods.

The debugger shows wkform as the correctly subclassed form (i.e.
FEditCommand or FEditQuery).

Any suggestions welcome.
