Specifying Input Arguments
All TIBCO BusinessEvents primitives (except Object) are supported. Appropriate boxing and unboxing of XML primitive types to TIBCO BusinessEvents primitive types is handled. For more details, see Rule Language Datatypes.
You can pass null values. Select the argument in the Activity Input panel of the Input tab. Click the Edit Statement (exclamation point) button. In the Edit Statement dialog, Content tab, check the Set Explicit Nil check box. If xsi:nil==true, then a null is passed as the argument.
Base Concept and Base Event are supported as argument types. You must map a specific type to the base concept or base event. Open the Edit Statement dialog, and in the Type tab, select the Type Substitution check box. In the Type field, select XML Type Reference. Select a Schema and a Type.
