Click Validator on the Debug menu to display the Host Integrator Validator. The Validator evaluates your host application model for errors. The Validator must report no errors with your model before a Host Integrator Server will allow you to deploy it.

The Validator evaluates the following aspects of a host application model:


All variables must have a unique name and be complete.


Model tables are tested for the following:


All entities must be unique, and there must be a valid operation that is able to navigate to every entity in the model.

Note: A warning will appear if there is no navigation between an entity and the home entity.

Event Handlers

All event handlers must be up to date with the associated libraries. Click Rebuild on the Events menu to rebuild the event handler libraries.

Validating a model

Use these steps to validate a model:

  1. Open the model you want to validate in the Design Tool.
  2. Select the model elements you want to evaluate by clicking the check box next to it.
  3. Click the Validate button. The model's features will be validated as described above. When the validation concludes, a validation report appears in the Validation results box.
