New pattern attribute "is_paginated" introduced in Paris is not backward compatible - Known Error

New pattern attribute "is_paginated" introduced in Paris is not backward compatible Description Patterns created or modified in Paris release that contain one or more "custom_operation" steps will contain a new attribute, named "is_paginated". These patterns cannot be imported into earlier releases, as the pattern parser will fail due to the unknown attribute.

As a symptom, you might see the following message:

Errors loading ndl: [XtextSyntaxDiagnostic: null:98 mismatched input 'is_paginated' expecting '}', when launching some of the Patterns

Steps to Reproduce

Create or modify a pattern in Paris release that contains one or more "custom_operation" steps. Export this pattern via an update set and import it into a pre-Paris instance. Attempt to load the pattern in the pattern designer. It will fail and you will see an error that indicates the parser does not know what "is_paginated" is. Please note that if you attempt to manually remove the is_paginated attribute in the pattern designer in Paris, once you click Save the attribute is re-introduced into the pattern.

Workaround This is expected behavior and by design in the current releases, but perhaps the following workarounds may provide an alternative solution for your use case.

Option 1:

Copy pattern NDL from new version. Paste NDL into the pattern for old version, then remove the is_paginated line from the pattern before saving. Save the pattern. Option 2:

Export the pattern from new version. Modify pattern XML to remove the is_paginated line from the pattern. Import the pattern to old version. Additionally: Try to develop pattern content on the oldest supported version to maximize compatibility.
