Why does saving data fail with validation errors?
Save failures typically occur when data violates constraints defined in the data model or when required fields are empty. Common causes include: attempting to create a relationship that violates cardinality rules (e.g., adding a second link where
cardinality is set to many-to-one), picking entities from outside the allowed moduleFolder or moduleName scope, or submitting duplicate property values where uniqueness is enforced. The error message usually includes a numbered list of failing conditions.For detailed resolution steps, see Resolve Validation Errors.Why do dynamic value expressions return empty results?
Why do dynamic value expressions return empty results?
Dynamic value expressions (using
$context syntax like $context.source.document.component) resolve at runtime based on the current document context. If a dynamic expression returns an empty result, verify that the source document has the expected property set. For example, $context.source.document.component only works if the Polarion document has a component property assigned. Missing context values resolve to empty strings, which can cause picker constraints to match all items or no items depending on the filter logic.See Sheet Configuration Guides for more on dynamic values in source configurations.
