password vault

Hello to all.
I have to install JDK 8.212 and Jboss EAP 7.2 on W2016
During the installation (I use GUI) I add a password vault and datasource.
Then I set some datasource using web console and find in standalone.xml that only first datasource was masked by password vault like ${VAULT::datasource.mydata::password::1}.
All other datasource password are in blank text.
How can I automate replacing blank text password to masked by vault?
How can I add datasource inserting blank text password in web console to store masked in standalone.xml, or I have to manually add it in vault and then insert this mask in web?
