> I created a slider view in the Ambari-Admin UI. The view had one masked parameter {{ambari.server.password}}. I entered "admin" and saw in the POST that the decoded value was uploaded:
> {code}
> {
>   "ViewInstanceInfo": {
>     "instance_name": "s2",
>     "label": "s2",
>     "visible": true,
>     "icon_path": "",
>     "icon64_path": "",
>     "properties": {
>       "ambari.server.url": "http://tdk-1:8080/api/c1/clusters/tdk",
>       "ambari.server.username": "admin",
>       "ambari.server.password": "admin",
>       "view.kerberos.principal": "a",
>       "view.kerberos.principal.keytab": "aa"
>     },
>     "description": "s2"
>   }
> }
> {code}
> After saved, I editing and changed another param (say view.kerberos.principal). This broke the masked param. The reason is that the GET call to view parameters gives the encoded value.
> So POST takes decoded values and GET provides encoded values. So the next time UI PUTs, the encoded value is put resulting in original value corruption.
> The API should either always provided encoded or decoded values, but not both.
