If the property has a CalculatedECSpecification custom attribute set on it, check if the specification has a 'Parser Regular Expression' set. If this expression is not set, the property is treated as read only.
Another thing to check is the element associated with the item with this property in the i-model. Values are not being calculated for properties with CalculatedECSpecification. Currently CalculatedECSpecification custom attribute is supported only for string type properties. Make sure that the property with the CalculatedECSpecification custom attribute is a string type property. When I try to save a transformation script, I get an error similar to " Could not load file or assembly 'Bentley.
Most likely this error is due to a missing redistributable on your machine. ExtensionDirectory' threw an exception. The specified module could not be found. In general terms, this involves checking to see the contents of the i-model meet the information requirements of the consuming application or user in the workflow. As such, i-model Validation plays a critical role with ensuring the required information is delivered.
It provides tools for creating and maintaining validation standards, as well as, evaluating schema and i-models against standards and then reporting and managing the results. For more information on the capabilities provided, refer to the Help documentation delivered with the product. It is accessible through the Tools menu. Validations are defined and executed in transformation scripts using the Validation transform.
The Validation transform is used to assess the quality and completeness of i-models according to Rule Libraries defined for various information exchange workflows. The Validation transform leverages the same underlying technology used by Bentley's i-model Validation Explorer. Since it packages the validation technology into a transform, this transformation allows for the inline validation of i-models in i-model Transformer scripts.
With this capability, someone composing a transformation script can validate input i-models consumed by the script, or output i-models produced by the script. The validation of i-models is driven by Rule Libraries that describe the specific aspects of i-models that should be evaluated. For example, one could perform a validation that ensures that all items of a given business class have a business key defined.
The results of a validation transform can be used to halt the execution of a script if, for example, a particular severity of rule violation is detected , or the results may be passively saved while the script continues to execute.
Options for saving the results as an Excel file, or as an XML report, are presented in the Transform Builder interface. The required parameters include the full path to the i-model to be validated and the validation options. The validation options are a collection of parameters that will be passed into the Validation engine. This includes things like specifying a name for the validation job, and what Rule Library to use to perform the validation.
For additional information on the validation parameters, in the i-model Transformer builder form, under Help — Contents, refer to Transforms Reference — Validation. While the transformation scripts produced on the desktop have value in and of themselves on the desktop, they acquire greater value after being imported into the iCS for i-models environment.
Associating a transformation script with an iCS Job means a transformation can be scheduled to happen on a recurring basis and run incrementally.
