In OpenWGA before 7.2 when using <tml:item name="someName"/> OpenWGA tried to retrieve the item value as follows:
- Values of WebTML variables (local vars, session vars, portlet vars) by variable name
- Values of mapped item values
- Values of Content Items
In OpenWGA 7.2 (with designs of version compliance 7.2 or higher) items are treated as "item expressions".
