I have a multiple file directory format inheriting from qiime2.plugin.model.DirectoryFormat.
The framework is invoking the _validate_ method twice when I output to this format. I am wondering if this is by design or if I have somehow triggered this by something that I have done?
My _validate_ method is a little bit slow so I am a bit concerned by the multiple invocations !
Could I please get some insight into what might be going on here?
