FlexGui - function load_file

A push button with function load_file, works fine. In my case it is used from an input panel, where parameters can be altered. If the file did run already and is loaded, then alter some values and hit the button 'run file', it is not updating with new parameters. So i need to reload the file to update with new parameters. Is there a way to always reload the file, when the function load_file is used?

 

At the moment i am testing with hal pins, because of the option 'start from current position' . To have the correct preview, it only worked with hal. The loaded file is just a translation file to call the subroutine. (The subroutine can be used standalone, in gcode or like here from the ui) It is working, i just have to rmember to reload, when parameter changed. Still pending, set a parameter eg  #<_RUNONCE> , which allows the routine to run only once, then have to start from  the panel with known parameter for further use. What i have done so far is mostly working as desired. The sidepanel is a stacked widget with 16 layers when completed
