# Spotting Mistakes with VDL Hints

When you are developing Views, Xpress Insight can provide feedback by flagging some classes of mistake or sub-optimal cases.
Examples include:

- Forgetting to specify `value` or `label` on an entity—this would be a mistake at development time and can easily be rectified by adding either `.value` or `.label` to the end of the entity reference.
- Accessing an entity for which data has not automatically been batch fetched—This hints that the VDL engine could not determine the usage of the given scenario/entity combination and you should consider providing more information in the VDL to improve performance.

Hints are only shown when you are in debug mode—see Debugging Custom Views in the Web Client. They appear in the web browser's console window.

All hint messages are prefixed with `[VDL HINT]` so you can easily search for them.
