Writing a PropertyBasedFileType plugin and I get infinite "Finishing" progress dialog

[Makuna]

I am new to developing plugins for Paint.Net, so it I suspect  I am missing something simple.

 

Below is the fledgling plugin that seems to correctly provide properties for save dialog ("save Configuration"). But after the hitting OK on it I get another popuup "Save Configuration" dialog with a cycling dialog bar and the word "finishing" above the progress control.  The problem is it never goes away.  Pretty much requires I terminate Paint.Net.

 

Attached debugger and didn't see any exceptions being fired.  My OnSaveT is empty.

 

I am using the latest version 4.0.9.

This might help explain some of the details...   http://forums.getpaint.net/index.php?/topic/31645-paintnet-filetype-plugins/?p=424863

 

Something Midora suggested a while back when I was developing a filetype plugin: http://forums.getpaint.net/index.php?/topic/31674-csv-comma-separated-values-filetype/?p=425159I'm not sure if he got around to adding it to the template.

THANKS!  The IsReflexive override was the needed part to allow it to finish.

Pleased to hear that. Good luck with the plugin!
