Expansion.getSampleMapList() always empty - full expansions

[Christoph Hart]

@David-Healey I think the better solution would be to include a check in the expansion loading phase that aborts the loading if samples are not found. There‘s a system to handle expansion errors gracefully (eg. if the encryption key doesn‘t match) and this would be a pretty simple addition.

[David Healey]

@Christoph-Hart sounds good, and I'd be able to respond to this in the error handler?

[Christoph Hart]

@David-Healey yup, with this one here:

https://docs.hise.audio/scripting/scripting-api/expansionhandler/index.html#seterrorfunction

[Christoph Hart]

Alrighty, it's pushed and I checked it in a minimal setup, but can you verify that this works in Rhapsody?

Also you might want to test the procedure of installing expansions to ensure that it doesn't throw a false positive there (it might be possible that the expansion gets initialised before the samples are extracted).

[David Healey]

@Christoph-Hart Thanks, I'll give it a try shortly and report back!

[David Healey]

@Christoph-Hart First try, it reported the error but then continued to load the expansion

if(missing1.isNotEmpty() && missing2.isNotEmpty())

I suspect this should be || instead of &&

[Christoph Hart]

@David-Healey no the function is a bit weird and used at another place. If everything is fine then it returns an empty string otherwise the filename. Since we‘re checking both sample folders one of them will always return an error so we need the logical and.

[David Healey]

@Christoph-Hart Ah ok I get it, so the problem is for me it's still loading the expansion. I've only tested in HISE so far. I'll compile now and see if the same issue is there.

[David Healey]

@Christoph-Hart Looks like I was mistaken. The error isn't firing. What I was seeing in the Console was errors from the Samplers telling me they can't find the monoliths after the expansion had started to load.

[Christoph Hart]

@David-Healey hmm but that should be covered - when there is an error the entire loading process is aborted so the samplers should not be created at all.

[David Healey]

@Christoph-Hart Not happening here with full expansions. I'll add some breakpoints and debug.

[David Healey]

@David-Healey Hmm I must have messed up my merge somewhere because even though I have that commit in my branch history that whole section is missing...

[David Healey]

@Christoph-Hart Found it, there was some merge issue.

It's not working correctly though. The callback doesn't seem to fire. I put Console.print in there but it never runs.

The expansion seems to be kind of half loaded. If after triggering the error I hit compile in my script, I'll get some errors about files not being found and my Interface won't render properly as if it's trying to load another project (the expansion) but is missing some files.

By the way, in the next version of Rhapsody I plan to go back to using hr files instead of the zips, so you might want to drop that mode before HISE 5.

[David Healey]

Doesn't seem to trigger any issues when installing an expansion, but since the error handler isn't triggering anyway it could just be being masked.
