The revision r866 should solve your issue. Is it possible for you to try this version?

On the other hand, I would like to ask why do you use LiteralData? rather than ComplexData? for inputs such as master and slave? Indeed, you can use the "xlink:href" attribute of the input reference node to have direct access to the value rather than having to download the input data from your service code.

After the first tests, the problem seems solved. Thanks for your help and celerity.

Are printed only the LowerCorner? and UpperCorner? of 1 input

Please, can you try using the r868? It should solve the issue of missing values for the LowerCorner and UpperCorner fields.
