> In our application of MetaModel we are now seeing some situations where the ExcelDataContext
is throwing exceptions due to internal IDs of sheets are not mapped to table names at the
time of executing a query.
> It happens because we have one DataContext which is used to explore the schema, then
the query is built and then later another instance of ExcelDataContext may fire the query.
But it doesn't work properly because the second ExcelDataContext has not yet loaded it's schema
definition.
> We already fixed this issue in eobjects.org MetaModel (needed a hotfix urgently), see
this revision:
