Parameters which are resolved before the input harvester dialog pops up will not show up. They get resolved by the various preprocessors in the preprocessing chain, which is applied before the module is actually run. The InputHarvester -- which is what pops the dialog box -- is (IIRC) the final preprocessing step before run happens. We could add a way to mark parameters which are not desired to be shown in the dialog box. What is your use case for a parameter you want to have in the script, but never shown to the user in cases where it is still null? > 2) A net.imagej.overlay.RectangleOverlay parameter, although properly > populated, provoques an Exception after the execution of the command. > (more details and stacktraces below) As I mentioned in the other thread: try with Overlay instead? We could certainly make it autofill parameters with specific Overlay subclasses too—just need to confirm first that that is indeed your problem. > 3) When a new preview is triggered, and that preview modifies numeric > parameters, then the numeric values visible in the gui dialog are > updated except for the NumericField on which input has triggered the > call to preview(). It is a programming error for the preview() function to modify parameter values. Use callbacks instead, which occur before preview() is called [1]. > 4) It would be nice if a parameter could have a label even if > ItemVisibility is MESSAGE Fixed [2].
