The Mapping to Node &ATTRIBUTE_NAME& Has Not Been Completed.

Question

Hi All,
Could anybody tell me when this exception arises.
we could not track this exception as all the mappings have been done as desired.
Need help immediately.

ARti.

Hi Aarti,
I encountered the same problem, but could resolve it.
There are two kinds of context mapping possible:
1)Cross component context mapping - In this case, the properties of the interface context node of the used component would look like:
Interface Node: X
Input Element (Ext.): must not be set
Then in the COMPONENT CONTROLLER of the using component, map the desired context node on the left hand side (of the component controller) to the interface node of the used component on the right hand side.
This is done when we need to receive value of the interface context node of the used component in the using component.
2)External context mapping: In this case, properties of the interface context node of the used component would look like:
Interface Node: X
Input Element (Ext.): X
Next in the CONTROLLER USAGE in the using component(this is a new node added in the hierarchy in SE80 when displaying the WD component, when component usage has been declared in the current component), right click the desired component usage and select 'Create controller usage'. Now it is here where you define mapping between the interface context node and the context node of the current component controller. By doing this, component controller of the using component would act as the data source.
This is done when we need to pass value to the used component from the using component.
The important point to remember is that whenever attribute Input Element (Ext.) of the interface node has been marked as X, ensure to define a mapping for this context, else it results in a runtime error "The Mapping to Node COMPONENTCONTROLLER.1.<interface_context_node> Has Not Been Completed" .
