1.Added a pure-reference shortcut in processValue to detect values of the form ${param} and resolve them directly from Binding before template rendering.
This preserves the original object type (e.g., Map, List) and prevents unintended stringification by JinJava/Groovy.
2.added tescases as per this doc
