If you think about it, this is an incorrect usage of the constant values. It would only make sense for lists of exactly one constant value. That's why this was written in the [documentation](https://hop.apache.org//manual/latest/pipeline/transforms/metainject.html#_inject_metadata_tab): ``` When specifying constant values for grouped lists of values like fields or filenames please note that there isn’t a good solution for that. Best practice is to use a [Data Grid](https://hop.apache.org//manual/latest/pipeline/transforms/datagrid.html) transform to inject a complete set of constant values. You can map those in this metadata injection transform. It will do its best to accommodate you by allowing you to inject a single row in the group with the specified constant value. ``` The way to solve this bug is then to throw an error I think, when incorrect/dangerous usage of the <const> values is made. -- This is an automated message from the Apache Git Service.
