Error using valueSet.gettext()

21 Views

I have a dropdown by key that is filled in the controller using the following code:

for (int i=0; i < wdContext.nodeZ360_Business_Unit().size(); i++)

{ valueSet.put(wdContext.nodeZ360_Business_Unit().getZ360_Business_UnitElementAt(i).getZzcode(),

wdContext.nodeZ360_Business_Unit().getZ360_Business_UnitElementAt(i).getZzdescription());

}

when I select the DD I want to set a context element with the text attribute from the DD. In the view of my Application onActionSelectedBusinessUnit(...) I have the following code:

IWDAttributeInfo attinfoBusUnit = wdContext.getNodeInfo().getAttribute("addBusUnit");

ISimpleTypeModifiable modinfoBusUnit = attinfoBusUnit.getModifiableSimpleType();

IModifiableSimpleValueSet vsBusUnit = modinfoBusUnit.getSVServices().getModifiableSimpleValueSet();

wdContext.currentContextElement().setBusUnitDescription(vsBusUnit.getText(wdContext.currentContextElement().getAddBusUnit()));

I get the following error when I select the the BusUnit DD:

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

Could anyone help me solve this error?

thanks in advance
