In the latest version of Rhino 7 on Windows, I’m unable to install my plugin which has been working since Rhino 6. I’m not sure when it stopped working, because I always had a valid license for the plugin so it never went into license validation. However if I try to do a fresh install, it fails. It still works in Rhino 7 if I register the plugin via Rhino 6.
The problem occurs in my Plugin OnLoad which looks like:
protected override LoadReturnCode OnLoad(ref string errorMessage) {
// note: there's currently a bug in Rhino 6 where a null mask does not show the text box entry, so we supply a mask.
var mask = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa";
var rc = GetLicense(LicenseCapabilities.CanBeSpecified, null, ValidateProductKey, LeaseChanged);
if (!rc)
return LoadReturnCode.ErrorShowDialog;
return base.OnLoad(ref errorMessage);
}
When I drag the plugin into Rhino, first I see an IndexOutOfRange exception before the validation dialog appears:
Then I see the validation dialog:
If I click “Enter your license key”, I see a null reference exception within the Rhino code ValidationClient.dll!ValidationClient.UI.Views.EnterLicenseKeyView.EnterLicenseKeyView(ValidationClient.UI.ViewModels.EnterLicenseKey step)
and then Rhino says plugin loading failed.
I just tried updating to the latest RhinoCommon and the problem continues.
I attached the sample plugin.
