When creating a new dynamic host management connection with the piggyback connector type, any edit to custom attributes in the form would not be stored correctly.

When editing such a connection, any custom attribute value set would show up empty.

If you have previously configured a dynamic host connection with custom host attributes, review its configuration after this Werk has been applied. The configuration will now be displayed as it has been used and will be updated correctly when saved.
