Many thanks TIG, your first code line does perfectly the job.
In fact I have many instances of the same component, and each one is differentiated by a unique name.
And just by removing s.clear I can make multiple selections, which is exactly what I intended to do.

You made my day !!

Dear all,

I'm a complete beginner with Ruby language, could anybody help me to write the necessary code to select a component instance in a given model by its name ?

Many thanks in advance
