LAWO - MC²56 MKIII - Ember+ protocol - No Label layers available after a get directory

[yboujraf]

Dear @KimonHoffmann

I already posted an issue to Lawo ticketing but when I talk about EmberPlusViewer as tools and crashes they send to github ;-)

I am using the Ember+ lib from Lawo and when I am asking a get Directory for the matrix node, I receive the path for the label layer and could make crosspoint with success.

Regarding label layers :

The label layers are declared in the emberTree structure. But unfortunately , those paths didn't exist in the EmberTree structure that's why EmberPlusViewer crashed each time I 'd like to change the label layer.

This is a copy of the EmberTree Structure discovered :

EmberPlusViewer - Get Labels

The EmberPlusViewer discovered the number of layers but finally nothing in the EmberTree

A dumfile is generated and added in this issue

EmberPlusView crashed.2020-02-12 04-49.zip

Conclusion :

How to know the label of each source & target for each matrix available in the MC² or Nova73HD ?

Thanks if you could highlighting me how to get the label layers with Ember+

(According to the standard, the branch to contains the labels, can be "invisible" when walking the tree, but must accessible when requested directly.)

Dear @mywave82

After reading the latest ember+ specification https://github.com/Lawo/ember-plus/blob/master/documentation/Ember%2B%20Documentation.pdf

What you refer is only for the ParametersLocation

I will check with my developer when expanding the emberTree structure to check the QualifiedMatrix properties, if Labels is defined and basepath

• if the labels path are already existing during the expand do nothing
• if no path discovered in the EmberTree do the GetDirectory for each label path layer and add it in the EmberTree.

Regarding the tyniEmberPlusRouter, the label layer is included in the EmberTree

Dear @mywave82

After a getDirectory from the basepath (Layer), it works, I can retrieve the labels ;-)
