Problem with Python component in GH

[Mitch]

I posted this over in the GH forum, but I though I'd post it here too, as I don't know who's watching out for this stuff:

Every time I reopen a GH definition made previously using a Python component - a simple 3 line script that has one input and one output - the output connector is missing. I have to add it back in. This is repeatable and has happened several times lately.

Also, when I add the output connector back in and rename it from "a" to let's say "result", I see its name in the tooltip as "a (result)". Only when I add another output which is then again named "a" by default does the first one change to just "result" and not "a (result)"

Lastly, if I copy the component inside the same definition using Ctrl+C/Ctrl+V, the output is again missing. Something very odd going on, and it has to do with how the 'a' output is hooked up, in combination with the 'out' output.

To illustrate the point -
From the Math menu, pull out a new Python component (no script necessary). By default, it has 'x', 'y' as inputs and 'out', 'a' as outputs. Right click the component and close the 'out' output. Now copy the component. It will go red and the 'a' output is missing. Now, grab a new Python component. Close the 'out' output as before (leaving 'a'). Add a new output 'b'. Copy the component. The 'a' output is missing, but the 'b' output is still there.

This is GH 0.90010 in Rhino 5 x64 RC1

Thanks Mitch. I'm watching out for this stuff and noticed your post on the grasshopper forum; just didn't have the time to reply yet. I'll see what I can do about tuning up the component.

Ok, thanks Steve - I guess you haven't gotten to this yet, still there in GH 0.90014 and V5 RCFinal... I know you have a lot of other stuff to do right now, so no worries.

The bugs are entirely in the component code itself which is good since it means we don't have to change any of core Rhino code in V5 "RCFinal" to fix things. I'm hoping to be able to take some time in the next week or so to do some tune-ups on the component.
Thanks,

It should work in 0.90014, it does here (doesn't crash, that is)... --Mitch

There's also this one: http://www.grasshopper3d.com/forum/t...ource=activity

Now I'm not sure if this bug is caused on an individual component basis (as it also happens with certain mesh components in Grasshopper as well). However if it is, I thought I would just mention here as well.

Best,
Anders

thanks mitch,
it started crashing again, solved it (for now) replacing ghpython for this component´s version:

Diego,
My best guess is that you have two copies of ghpython on your computer and somehow the older one is getting loaded.
