Fix OutputVectorDataParameter inside a choice

Cédric Traizet requested to merge bug_param_choice_vectordata into release-7.0


This MR is a fix for this bug reported on the forum.


This is a bug in the application engine, it affects the ZonalStatistics application, and maybe others.

if a vector data parameteris the child of a choice parameter, and if the choice is non actives (i.e. non chosen) while the vector data is, the Application class will try to create the output vector data, leading to a crash. It can be reproduced with the command:

otbcli_ZonalStatistics  -in S2A_ROI.tif ImageClassifier/input/classif_train.shp -out raster -out.vector.filename /tmp/out.shp -out.raster.filename /tmp/out.tif

It happens on Monteverdi because a default value is attributed to vector data parameters, activating them.

The fix simply use the recurse functionality of the IsEnabled(string paramKey) of the Application engine to check if the choice is active before attempting to create the output data.
