----------------------------------------
Summary: Excel DataContext may break if schema is not loaded at
time of executing query
Key: METAMODEL-47
URL: https://issues.apache.org/jira/browse/METAMODEL-47
Project: Metamodel
Issue Type: Bug
Reporter: Kasper Sørensen
Assignee: Kasper Sørensen
Priority: Critical
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:
