23 Views

Runtime exception -


com.sap.tc.webdynpro.progmodel.context.ContextException: MappedAttributeInfo(First_CompView.Color.VALUESET): must not modify the datatype of a mapped attribute

Code for DropDownByIndex----


IWDAttributeInfo attrInfo = wdContext.nodeColor().getNodeInfo().getAttribute(IPrivateFirst_CompView.IColorElement.VALUESET);

ISimpleTypeModifiable msType = attrInfo.getModifiableSimpleType();

IModifiableSimpleValueSet valueSet = msType.getSVServices().getModifiableSimpleValueSet();

valueSet .put("","choose");

valueSet .put("1","black");

valueSet .put("2","red");

valueSet .put("3","blue");

Getting Runtime error in the line----


ISimpleTypeModifiable msType = attrInfo.getModifiableSimpleType();

I am unable to set different colors as DropDownList dybamically.

Please help me out.
