Apache Taste String Id

Is it possible to use an id which isn't an integer using taste?

My model may have preferences for remote products. To differentiate these we use a string identifier which is "locationId:itemId". I can't see support for this however.
Is there any other way to get around this?

Solution

  • Yes, though it's going to slow things down. Look at IDMigrator and implementations and usages in the framework. This is how you can get some help in translating to/from integer IDs automatically.

    There is no support for this in the distributed version.
