The crashes are now fixed. The rest is to be addressed in the .blend file itself.

Add missing semicolons.

Short story: neither of update or tagging should happen from set() functions.

ID.update_tag(...) doesn't refresh on the viewport while scrolling in the timeline. Going to edit mode refreshes the mesh in the viewport.

Fairly sure calling view_layer.update() within a set function isn't supported.

A different diff ended up being committed.

I see, thanks but why doesn't this happen when baking for example smoke in the same way?

The cache is empty when I open the file afterwards

Right, all properties should use the character index not the byte offset.

Can confirm.
This was always crashing, not really designed for usage outside of the FileBrowser itself...

This patch deals with set selection: D5881

so now it would be possible to get back selection to what it was before the last undo using this

Thanks, committed rB73a6fcfa80020615f081b75aeb6a6ed90405097a

@Amir (Warrior) I checked with a master build before my previous comment. I hadn't tried in 2.79 for a while but just checked and it hasn't changed, not that any fixes will be done to 2.79.

@Shane Ambler (sambler) I haven't tried this in 2.8x. Did you try it with both 2.79x and 2.8x?

@Amir (Warrior) No. Just tried with 741d7d60ed90

@Jeroen Bakker (jbakker) Does this fix have anything to do with this issue?

Thanks, committed rB6cb1e38c87168b0ab83ca907bcf537d50c263454

Managed to do it, but it is a hacky solution, so hacky that I'm just gonna post it here instead of actually going through with a commit.

Solved in rB68d1f0915831: Shading Modes: Material and Render Preview.

2.81 release is scheduled for november as far as I remember, I'd bet they won't release a corrective 2.80a version but rather count on 2.81.

The fixes will be available in the net round of nightly builds and in 2.81.

Thank you Sergey. Is the 2.8 build updated after the final release last month with these fixes? Should I reinstall the 2.8 version? Or is this fix only in the 2.81 version?

Does it mean it may still crashes under certain circumstances?

Great news, thanks @Sergey Sharybin (sergey) !

There are the following changes now made:

@Sergey Sharybin (sergey) : Just a note I have added this to 2.81 milestone (since it was set to "High"), I think you are on it already, right?

I think this should be custom properties for View3DShading, using RNA_def_struct_idprops_func.

More than a week without reply or activity. Due to the policy of the tracker archiving for until required info/data are provided.

Archive this since fixed in 2.81...

I understand, but this worked in release candidates and prior. I did not see any info that bl_idname for menus explicitly needs _mt_ in the idname as well. That's not quite clear on the info page

hi, this is a fairly normal warning, in your file you have the bl_idname wrong

Yes sorry for missing file. Ive tried adding the minimal parts need to reproduce this. Prior this would work when only the Class header had _MT_ in it. I think since release candidate 1 or 2 it stopped. Until yesterday i didn't looked at it. but had to since i wanted to update an addon. I noticed that now the bl_idname also needs _MT_ in it properly. Yet operators still work using say qs.quick_switch.

Please provide a Python script to reproduce the problem.

Glad to hear, closing then...

Blender 2.8.1 build now has Python 3.7.4 and the BlenderGIS add-on now installs. Thank you.

Wait for buildbot to be able to build new one, it should have the new one.

Console states 3.7.0. That was from a version of Blender downloaded again today, 22 August. Do I need to try that again or go elsewhere for a 'new' build? Thanks.

Check python console and if the version is 3.7.4, your build is up to date.

please fix this!
flip fluids is a must for any water sim in blender, the internal fluid simulation engine is a pain.
its a shame blender devs haven't fixed this bug already.

Also wanted to check whether this really was a Blender issue or the BlenderGIS add-on, after all?

Hi. Still the same error I'm afraid. Latest grab attached. I'm a little confused why it appears to be trying to look for a local folder on ‘brecht's’ drive when that would be impossible. Good luck... again. Thanks.

Interesting, will have a quick look...

The add-ons are not made by me.

Python is now updated to 3.7.4, check if it works now.

a system that announces when an addon can be updated would be fantastic :)
