Not Applicable
Steps to Reproduce
- Create a Datapage 'DemoDataPage' of Definition class say 'A-B-C' with one parameter 'anotherKey' and Keyed access wtih 'pzInsKey'.
- Create a PageList property 'DemoPageList' of Definition class 'A-B-C' (Same definition class as the Datapage has) and it should pre-populated.
- Create a Page property 'DemoPage' of Definition class 'A-B-C' (Same definition class as the Datapage and Pagelist have) and set the Data Access 'Refer to Datapage' and pass 'anotherKey' and 'pzInsKey'.
- Create an activity and loop through the PageList property and set some of the local variables with the properties of each page using Property-Set along with 'pzInsKey' and 'anotherKey'.
- Try to access any of the property of the DemoPage and the property will be null / blank.
Root Cause
Expected Behavior, but a custom design fault.
Resolution
In order to populate the page property 'DemoPage' one must create a new page in the activity and pass the key(s) in the page, that is to Property-Set, so that the keys can be propagated to the DataPage 'DemoDataPage' (pass keys 'anotherKey' and 'pzInsKey' as parameters) and the property can be populated.
