Call a microflow with a list containing only 1 object from a widget ?

I'm currently working on a widget, which call a microflow defined as follow:Event MicroflowBehaviorSome description.  Within my widget, when I call this microflow with a list containing 2 or more objects, it works fine. But if my list contains only 1 object, the parameter is not sent to the microflow. Here the call: mx.data.action({ params: { applyto: "selection", actionname: this.myMf, guids: guids // This is an array of guids }, callback: function() { console.debug("OK"); }, error: function (error) { console.debug(error.description); } }, this);   I searched the forum, and it seems that it was a known issue 5 years ago, submitted with the number #9116. (cf. https://forum.mendixcloud.com/link/questions/3633) What is the status of this bug? Is it not solved, or is it the way that I call the microflow the issue?   Thanks in advance
