Ok, thanks for the the tip.

I changed the XML to this one:

    <outputs>
        <data format="showelab-dataset" name="trainingDataset"
label="Training Dataset extracted from ${input_dataset.name}">
            <change_format>
               <when input="format_options" value="fbk"
format="fbk-svm-dataset"/>
            </change_format>

        </data>
        <data format="showelab-dataset" name="validationDataset"
label="Validation Dataset extracted from ${input_dataset.name}">
            <change_format>
               <when input="format_options" value="fbk"
format="fbk-svm-dataset"/>
            </change_format>

        </data>

        <data format="fbk-labels" name="trainingLabels" label="Training
Dataset Labels extracted from ${input_fbk_dataset_labels.name}">
            <filter>format_condition['format_options']  == "fbk"</filter>
        </data>

        <data format="fbk-labels" name="validationLabels" label="Validation
Dataset Labels extracted from ${input_fbk_dataset_labels.name}">
            <filter>format_condition['format_options']  == "fbk"</filter>
        </data>

    </outputs>

Still is not working, maybe the "<when input="format_options" value="fbk"
format="fbk-svm-dataset"/>" . Maybe it has some problem since the
"format_options" parameter is inside a "conditional" tag?

Thanks a lot for your time.
