There are several ways to do that. Let's say you have a persistent property

Property Problem As %String;

That you don't want anyone to see.

1. Make it private:

Property Problem As %String [ Private ];

It would not be displayed altogether

2. Add accessor methods:

Property Problem As %String;

Method ProblemGet() As %String [ ServerOnly = 1 ]
{
    Quit "****"
}

Method ProblemRealGet()
{
    Quit i%Problem2
}

Method ProblemSet(Arg As %String) As %Status [ ServerOnly = 1 ]
{
    Set i%Problem2 = Arg
    Quit $$$OK
}

This way default callers would get **** and only your app code can access the real value.

3. Do not project property to XML

Property Problem As %String(XMLPROJECTION = "none");

As ensemble message viewer is XML-based it would hide property from it.

4. Create a special datatype. For example MyApp.Datatype.Password datatype returns **** as Display and ODBC values:

Class MyApp.Datatype.Password Extends %String
{

ClassMethod LogicalToDisplay(%val As %String) As %String [ Internal ]
{
    q $case(%val,"":"",:"*****")
}

ClassMethod LogicalToOdbc(%val As %String) As %String [ Internal ]
{
    q $case(%val,"":"",:"*****")
}

}

To use it:

Property Problem As MyApp.Datatypes.Password;

5. Extract the property into a separate class and reference the object of that class.

These approaches could be combined.

You can subclass Ens.ContextSearch to provide dynamic settings lists. Docs.

Here's a sample class  that adds ability to select XData in Ensemble setting.

/// Ensemble settings interface implementation
Class Package.EnsSearchUtils Extends %ZEN.Portal.ContextSearch
{

///Get class Xdata list.
ClassMethod GetXDatas(Output pCaption As %String, Output pTopResults, Output pResults, ByRef pParms As %String, pSearchKey As %String = "") As %Status
{
    Set tStatus = $$$OK
    Kill pResults, pTopResults
    Set pCaption = ""

    Set tClass = $get(pParms("class"))
    If tClass '= "" {
        Set tClassObj = ##class(%Dictionary.CompiledClass).%OpenId(tClass)

        For i=1:1:tClassObj.XDatas.Count() {
            Set pResults($i(pResults)) = tClassObj.XDatas.GetAt(i).Name
        }
    }
    Quit tStatus
}

}

For example to add a setting XSLTTransformation to BH that would allow me to choose on XData from my Package.XSLT class, I can specify SETTINGS parameter like  this:

Parameter SETTINGS = "XSLTTransformation:Basic:selector?context={Package.EnsSearchUtils/GetXDatas?class=Package.XSLT}";

Check that stream is an object and contains relevant data:

write $isObject(httpResponse)

what data does it contain:

do httpResponse.OutputToDevice()

if it's not an object - what is it?

zwrite httpResponse

If everything is okay - stream contains what you expect it to contain, then what is the status of convert operation:

Set sc = ##class(%ZEN.Auxiliary.jsonProvider).%ConvertJSONToObject(httpResponse,,.Object,1)

write $System.Status.GetErrorText(sc)
zwrite Object
