Material is deleted when cloning

Dan Rathbun

The Ruby methods clone and dup, do NOT yet work upon SketchUp API classes.

We discussed this in previous topics:

Thank you, I fixed my problem by processing only materials used in the model:


aMat = Sketchup.active_model.materials.current
if aMat != nil and Sketchup.active_model.materials.include?(aMat)
   ...
end

We should improve this. But they would not make sense for Entity based classes as instances are persistent and have to be created via entity.add_*.

I just did the following in SU2014 and got a SPLAT!

Choose a material that is not in the model.
Open console.
test = Sketchup.active_model.materials.current test.name
Choose a material that IS in the model.
test2 = Sketchup.active_model.materials.current test2.name
Everything is fine.
Now,.. try to get the name of the previous material.
test.name
-- > SPLAT

I cannot reproduce this. Did you submit the splat? Did you include any info I can use to look it up?
Do you see this consistently? (Can you do a video recording?)

Dan Rathbun

I do think I sent in the Splat Report.

I do not have video capture software installed (unless it comes with Windows 7?)

This was 2 weeks ago... I haven't tried since.

Did you enter any details into the BugSplat? (So we can search for it.)

Dan Rathbun

I entered the steps that caused the splat, and then copied from the splat dialog, into the above SCF report.

SU2014 Win?

Ah! Found the crash report. And I realized I'd overlooked the last step in your instructions - accessing the name of the first material after it was not current any more. It's another bug where Ruby is allowed to get a handle to a transient material. I'm logging a new issue.
