Arguments
| Argument | Type | Direction | Purpose |
|---|---|---|---|
| MetaClass | BaseClass | In | The MetaClass to create the instance from |
| Result | RelationalObject | Out | The created instance, null if creation failed |
Usage
This activity is used to create new UBIK® objects during the execution of a workflow. Since it only needs to know the MetaClass to create objects from, it can be used to create regular content objects as well as properties or anything else.
 | This activity does not automatically save changes. If you want to persist the newly created instance, you need i.e. a subsequent SaveObject activity! |
Example
Load the MetaClass named PUMP, and create a new instance from it:
| Argument | Value |
|---|---|
| MetaClass | UBIKObject.Environment _ .GetSystemMetaClass(UBIK.Kernel.SystemObjects.METACLASS) _ .AllInstances("PUMP") |
