Multiple choices with only one choice
Created by: alexbruy
After writing the XML, some multiple choices have a single choice.
Some applications are split using different predefined values of a parameter (eg. mode, filter....; Segmentation is split using the parameter "filter"). But this parameter is still considered as a parameter. It was a choices which has only one choice. Some other parameters choices are removed during the XML creation. This can also bring a multiple choices with a single choice.
These parameters should be removed and their name and value should be added to the node cli_args_template #6 (closed).
