Starting from this discussion: URI Builder - PI Coresight Link i found out that the use of substitution variables is inconsistent.
- To resolve display names and parameter keys one can use substitution variables using the %Attribute% syntax. But the website address does not support any use of variables, giving error "Unexpected path delimiter index: -1". And some subsequent crashes of PSE...
- One can override the configuration string using 'path\attribute' types of substitution strings, but those are not supported when opening the configuration form or the URI builder.
I would like to be able to support substitution variables to be able to store the Coresight base URL in a configuration Element/Attribute, and refer to that in any URI builder resolving the URI for a specific display.
