In our D2007 application we are using a Webservice, accessed with a THTTPRIO object. When the TDatamodule containing the THTTPRIO object is Destroyed an access violation occurs.

This AV is raised when the TSoapDOMConvert is freed, which in turn executes:

TRefCache(RefMap[0].Instance).Free

calling

destructor TRefCache.Destroy;
begin
  FHREFs.Free;
  FMHREFs.Free;
  FNodes := nil; //Causes AV
end;

FNodes is a TInterfaceList containing one reference to IXMLNodes, but the object seems to have been freed before all this.

Does anyone know this problem? How to solve it?
