external context mapping issue: cannot create nodes,no mapping defined yet

[Former Member]

Hello everybody,

I'm trying to use the external context mapping as it is explained in http://help.sap.com/saphelp_nw04/helpdata/en/d7/e551cf896c3a49bb87bb4ce38c99c8/frameset.htm

I did it in the past without any problem, but now, when i try to create a new node, i get the error "cannot create nodes,no mapping defined yet." This error appears as i try to create an element of the node (in the Internal Component), this way:

IPruebaNodoElement elto = wdContext.nodePruebaNodo().createPruebaNodoElement();

elto.setPrueba("Esto es una prueba");

wdContext.nodePruebaNodo().addElement(elto);

The mapping is correctly done in the "Embedder Component", and the attribute "isInputElement"=true in the Interface Controller of the "Internal Component".

Any idea, any clue?

Thank you very much in advance

Isidro,

Before accessing context try to invoke any method (if necessary, create fake one with empty implementation) on embedded component. Sometimes this helps.

Frankly speaking: I just read again, but very carefully, all the steps explained at

http://help.sap.com/saphelp_nw04/helpdata/en/d7/e551cf896c3a49bb87bb4ce38c99c8/frameset.htm.

Read it carefully and try to implement that example, that could be really helpful.
