In another thread last week, I tried to extend util:User by adding an
attribute. I eventually determined in the code that adding an attribute is
not allowed for this element. So I assumed that I could add a child
element, but also does not work. UtilCompiler.cs has the following code
foreach (XmlNode child in node.ChildNodes)
{
if (XmlNodeType.Element == child.NodeType)
{
if (child.NamespaceURI == this.schema.TargetNamespace)
{
SourceLineNumberCollection childSourceLineNumbers =
Preprocessor.GetSourceLineNumbers(child);
switch (child.LocalName)
{
case "GroupRef":
if (null == componentId)
{
this.Core.OnMessage(UtilErrors.IllegalElementWithoutComponent(childSourceLineNumbers,
child.Name));
}
this.ParseGroupRefElement(child, id);
break;
default:
this.Core.UnexpectedElement(node, child);
break;
}
}
else
{
this.Core.UnsupportedExtensionElement(node, child);
}
}
}
I previously wrote a CompilerExtension which added a child element to the
Component element. I see that it does not have the
this.Core.UnsupportedExtensionElement(node, child);
I want to extend the behavior of the util:User element to hide the service
account from the logon screen. If I am going at this the wrong way, what is
the correct approach?
Also in Compiler.cs I noticed the following comments at the end of parsing
the Component element:
// CompilerExtension must return a key path type, so
the component key path is either set or not (no automatic selection).
In searching the wix code I notice that only the DependencyCompiler and hte
UtilCompiler (only when parsing the Source attribute) sets the
ComponentKeypathType, so I assume that the case is overstated in the
comment.
