To all app developers out there, there was a recent change in the framework [1].

Currently if you disable a helm chart when you update an app it will be re-enabled by default on the newer version.
[sysadmin at controller-0 ~(keystone_admin)]$ system helm-chart-attribute-modify
usage: system helm-chart-attribute-modify [--enabled <true/false>] <app name> <chart name> <namespace>

system helm-chart-attribute-modify --enabled false MY_APP MY_CHART MY_NAMESPACE

The chart attribute(enabled/disabled) itself is stored in sysinv database in a column called 'system_overrides' (bad naming, will be aligned later).enabled

If you want to keep the disabled status during app update you can update the metadata.yaml ([2] example location for one app), adding at root level the following
maintain_attributes: true

There is more. You can override the behavior present by adding a special flag during 'system application-update'. You can force the information either way: reuse(will keep disabled the charts that were disabled) or not reuse(reset all the charts to be enabled).

system application[sysadmin at controller-0 ~(keystone_admin)]$ system application-update
usage: system application-update [-n <app name>] [-v <app version>] [--reuse-user-overrides <true/false>] [--reuse-attributes <true/false>] <tar file>

system application[sysadmin at controller-0 ~(keystone_admin)]$ system application-update -n MY_APP -v MY_VERSION --reuse-attributes true /path/to/tar.gz
