Referring ViewAttributeDefImpl properties from the dynamic UI tag
Referring ViewAttributeDefImpl properties from the dynamic UI tag
I have blogged on generating dynamic UI some time back. In case you missed them, here are the links
Model driven approach for building Dynamic UI
Enabling LOVs for Dynamic ViewObject attributes
Long living Dynamic Business Components
Here is a tip for you to refer the ViewAttributeDefImpl properties such as label and other custom properties from the dynamic UI such as dynamic table.
For example if you have set label for an attribute as given below, it can be referred from UI through
#{defXXX.propertyMap.label}
Code snippet for setting propertu for attribute definition in a dynamic view object(if you are not following this code snippet read Model driven approach for building Dynamic UI and come back)
ViewAttributeDefImpl attrdef= getDynamicAttrdef();
attrdef.setAliasName(col.getName());
attrdef.setProperty("label", getSomeNiceLabel());
UI tag snippet referring the property that we set in the above code.
