collapsing setting categories sometimes makes them all disappear
Open, LowPublic


While setting up prints, when collapsing an expanded settings category, sometimes all of the settings will be invisible with only the search bar.
The work-around is to put something in the search bar, delete it, and then all the settings re-appear.

@logan ,

This is relevant:

2019-01-09 07:39:59,438 - WARNING - [(140507555476864)-MainThread] LocalContainerProvider.LocalContainerProvider._saveCachedDefinition [243]: The definition cache for definition fdmprinter failed to pickle.

The problem you are hitting here is that you'll need to clear cache every time you are switching from 3.2 to 3.6 and back, because in 3.6 some CuraEngine options were removed and some were added.

So I cannot use the CuraLE installed on my workstation via the testing repo if I am using a local build for testing?

alexei added a comment.Jan 9 2019, 2:39 PM

@logan, You can use them, just make sure you have a single instance of CuraLE running and also that you are clearing cache when switching versions.

logan added a comment.Jan 9 2019, 2:41 PM

Hm, alright. I will keep an eye on this next time I have time to export WIP profiles, clear cache, update, and re-import.

Again today, fresh build of 3.6.4 generated yesterday running from a freshly cleared cache

@alexei What does that mean?
At least now I know it is a bug and nothing that I'm doing.

And another QML error:

@logan , Will need to see where exactly these errors are coming from.

logan added a comment.Feb 11 2019, 2:42 PM

Here's a log from today, more occurrences

I'll go ahead and rebuild and clear cache

logan added a comment.Wed, Feb 27, 9:45 AM

Still happening often, do you have enough logs or should I continue to post them?
