c.o.a.service.navigation.StaticModel - Ambiguity in finding a parent

[dmitry-lomakin]

During detailed checks of the 2.0-20, an engineer from Odin has found a warning in UI log file on management node during CCPv2 navigation for Spam Experts tab:

[root@oa73a ~]# tail -fn0 /var/log/pa/pui/pui.log  | grep Ambiguity
23:53:24.794 [default task-225] WARN  c.o.a.service.navigation.StaticModel - Ambiguity in finding a parent for 'view-plugin@http://www.odin.com/oa/billing/paymentmanagement#paymentMethodSelector'. Trying to assign 'plugin-placeholder@http://www.parallels.com/ccp-billing-financial-documents#payment-method-selector' but 'plugin-placeholder@http://www.parallels.com/ccp-billing-financial-documents#payment-method-selector' is already assigned! Behavior now depends on order of elements and packages!

This means that one view plugs to several different parent elements, which is wrong according to the ambiguity warning in the following documentation section:
https://doc.apsstandard.org/7.3/concepts/frontend/navigation/index.html#static-navigation

This can cause random 404 errors when navigating the CP. It is highly recommended to fix this issue in next application update.
