Validation Rules and Error Messages

Understanding and resolving Unwired WorkSpace validation errors helps ensure that mobile business objects (and the device applications that interact with them) perform as expected in an enterprise environment.

Validation rules are divided into sections based on where in the MBO life cycle (development, deployment, runtime) the validation rule applies and is enforced, and includes:

Severity and message - There are two types of messages generated if a validation error occurs:
- Warning messages - A non-fatal error that requires attention or a failure may occur at a later time.
- Error messages - The operation being performed fails. You must resolve the error.
- Message - the actual error message, if any, generated should the validation rule be violated.
Action - any additional details regarding the validation rule and how to resolve the error.

Note: Some validation errors can be identified in Unwired WorkSpace by the warning or error icon that appears within the context of the error. Examples include:

If you add an unmapped parameter to an attribute in the Properties view, a warning icon and message appear in the properties view, and the warning icon also appears in the header of the MBO in the Mobile Application Diagram.
Mobile application project folders in WorkSpace Navigator display warning or error icons should objects within the folder (MBOs, roles, personalization keys, and so on) be invalid. You can isolate the error by expanding the folder until you reach the object that is in error.

Other errors generate an error message, for example an error during deployment.

In general, be aware of warning and error icons and messages, and resolve them early in the development cycle so your MBOs behave as expected once deployed.

Common Validation Rules
These validation rules are common to all levels of MBO development (attribute, naming, operation, and so on) and enforced when developing the MBO and, in some cases, when you deploy the MBO to Unwired Server. Error/warning messages are generated when validation rules are violated.
Attribute Validation Rules and Error Messages
Validation rules are enforced during development of the MBO and, in some cases, when you deploy the MBO to Unwired Server. Error/warning messages are generated when validation rules are violated.
Mobile Business Object Validation Rules and Error Messages
Validation rules are enforced during development of the MBO and, in some cases, when you deploy the MBO to Unwired Server. Error/warning messages are generated when validation rules are violated.
Operation Validation Rules and Error Messages
Validation rules are enforced during development of the MBO and, in some cases, when you deploy the MBO to Unwired Server. Error/warning messages are generated when validation rules are violated.
Argument Validation Rules and Error Messages
Validation rules are enforced when mapping arguments and, in some cases, when you deploy the MBO to Unwired Server. Error/warning messages are generated when validation rules are violated.
Parameter Validation Rules and Error Messages
Validation rules are enforced when defining parameters and, in some cases, when you deploy the MBO to Unwired Server. Error/warning messages are generated when validation rules are violated.
Datatype Validation Rules
The Attribute, parameter, and argument datatype validation rules table describes validation rules for Mobile Business Object (MBO) length, and precision and scale datatypes.
Result Set Filter Validation Rules and Error Messages
Validation rules are enforced when defining a result set filter and, in some cases, when you deploy the MBO to Unwired Server. Error/warning messages are generated when validation rules are violated.
Relationship Validation Rules and Error Messages
Validation rules are enforced when defining a relationship between two MBOs and, in some cases, when you deploy the MBO to Unwired Server. Error/warning messages are generated when validation rules are violated.
File Mobile Business Object Validation Rules and Error Messages
Validation rules are enforced during development of a File MBO and, in some cases, when you deploy the MBO to Unwired Server. Error/warning messages are generated when validation rules are violated.
JDBC Mobile Business Object Validation Rules and Error Messages
Validation rules are enforced during development of an MBO bound to a database (JDBC) data source and, in some cases, when you deploy the MBO to Unwired Server. Error/warning messages are generated when validation rules are violated.
SAP Mobile Business Object Related Validation Rules and Error Messages
Validation rules are enforced during development of an MBO bound to an SAP data source and, in some cases, when you deploy the MBO to Unwired Server. Error/warning messages are generated when validation rules are violated.
Web Service Mobile Business Object Validation Rules and Error Messages
Validation rules are enforced during development of an MBO bound to a Web service and, in some cases, when you deploy the MBO to Unwired Server. Error/warning messages are generated when validation rules are violated.
Role Validation Rules and Error Messages
Validation rules are enforced when defining roles and, in some cases, when you deploy the MBO to which the role is assigned to Unwired Server. Error/warning messages are generated when validation rules are violated.
Personalization Key Validation Rules and Error Messages
Validation rules are enforced when defining personalization keys and, in some cases, when you deploy the MBO to which the personalization key is assigned to Unwired Server. Error/warning messages are generated when validation rules are violated.
Metadata Validation Rules and Error Messages
Validation rules are enforced when you deploy the MBO to Unwired Server. Error/warning messages are generated when validation rules are violated.
Playback Link Validation Rules and Error Messages
Validation rules are enforced during development and use of device application. Error/warning messages are generated when validation rules are violated.
Device Link Validation Rules and Error Messages
Validation rules are enforced during development and use of device application. Error/warning messages are generated when validation rules are violated.
