COM Exception

[rvaldes]

Hi, this is the problem:

When line parent.Elements.AddNew("<Element Name>", type); executes, throw a COMException with "Internal Error" message.

Any ideas??

[size=8] public EA.IDualElement AddChildElement(EA.IDualElement parent, EA.IDualElement child, string type, string stereotype, out bool success)
        {
            if (parent == null)
            {
                throw new ArgumentNullException("parent", "METESPA_Addin.Model.Dao:AddChildElement(EA.IDualElement parent, EA.IDualElement child, string type, string stereotype, out bool success)");
            }

            object element = null;
            success = true;

            try
            {
                if (child == null)
                {
                    
                 [highlight]   element = parent.Elements.AddNew("<Element Name>", type);[/highlight]
                }
                else
                {
                    element = parent.Elements.AddNew(child.Name, type);
                }

                success &= ((EA.IDualElement)element).Update();
                parent.Elements.Refresh();

                ((EA.IDualElement)element).Stereotype = stereotype;
                success &= ((EA.IDualElement)element).Update();

                ((EA.IDualElement)element).TreePos = parent.Elements.Count;
                success &= ((EA.IDualElement)element).Update();

                if (success)
                {
                    OnAddedElement(((EA.IDualElement)element).ElementID, ((EA.IDualElement)element).PackageID, ((EA.IDualElement)element).ParentID, ((EA.IDualElement)element).Type, ((EA.IDualElement)element).Stereotype);
                }
            }
            catch
            {
                throw new DaoException("METESPA_Addin.Model.Dao:AddChildElement(EA.IDualElement parent, EA.IDualElement child, string type, string stereotype, out bool success)");
            }

            return (EA.IDualElement)element;
        }[/size]

Some questions:

- Why do you use the IDualElement things? I've never used those interfaces, but always worked with EA.Element
- What is the value of the type parameter
- Do you use some kind of locking mechanism which could make the parent readonly
- Has the parent already been saved to the model (using Update())
- Do you have the same issue when you try with a name that doesn't contain "<" or ">"
- Does Repository.getLastError give you any info?
