Hadn’t used it since Ensemble 2009 ;-), to provide custom html output displayed by the management portal when viewing a message of a class extending Ens.MessageBody, you can override the %GetContentType() and %ShowContents() methods of Ens.Util.MessageBodyMethods in your message class.

Here is a small example :

Class dc.sample.msg.Message Extends Ens.MessageBody
{

Property Name As %String [ InitialExpression = "you" ];

// returns MIME content type
Method %GetContentType() As %String
{
    return "text/html"
}

// output content
Method %ShowContents()
{
    &html<<p>Hello,&nbsp;#(..Name)#</p>>
}


Storage Default
{
<Data name="MessageDefaultData">
<Subscript>"Message"</Subscript>
<Value name="1">
<Value>Name</Value>
</Value>
</Data>
<DefaultData>MessageDefaultData</DefaultData>
<Type>%Storage.Persistent</Type>
}

}

In the management portal message viewer, the message gets displayed as :

Size 201 181 181, all unit tests passed (including undefined argument, and additional .Type("abc,de","de,abc") --> Unsorted)
Thanks Eduard, I missed the extraneous quotes (my mind is still not entirely purged of strongly typed languages habits 😅)

ClassMethod Type(a...) As %String
{
 f i=$i(r):1:$g(a){f j=1:1:$l(a(i),","){s l=$l($tr($p(a(i),",",j)," ")),c=$g(c,l),r=$s(l=c:r,r<3*l>c:2,r#2*c>l:3,1:4),c=l} k c} q $p("Constant1Increasing1Decreasing1Unsorted",1,r)
}

Hi,

To summarize the documentation :

  • ReplyCodeActions settings of HL7 operations is a comma-separated list of specifiers in the form <code>=<actions>, where <code> is an expression matching error condition(s) and <actions> is a string of one letter action codes.
  • All codes where <actions> consists of only 'W' (for 'log a Warning') will be evaluated, and a warning will be generated for each matching <code>.
  • Other <code> values will be evaluated in left-to-right order, executing the first matching <code> that has a non-warning <actions> value. As noted in the details for the 'W' flag, an error that only triggers 'W' <actions> will be treated as Completed OK.
  • if ReplyCodeActions is empty, a default setting is used. For HL7 operations, it is : 
    • :?R=RF,:?E=S,:~=S,:?A=C,:*=S,:I?=W,:T?=C

To match the application reject code in the HL7 ACK^O01 message in the example, and suspend all matching messages, use the following specifier, that matches all ACKs with MSA:1 = "AR" and suspend message, while retaining default behavior for other error conditions : 

:?R=S,:?E=S,:~=S,:?A=C,:*=S,:I?=W,:T?=C

Yes, ^SPOOL is the simplest way to achieve this. If you need a string rather than a global, you can just get all lines from ^SPOOL, for example :

ClassMethod ZWriteToString() As %String
{
 #Dim result as %String
 #Dim i,lineCount as %Integer
 
 kill ^SPOOL($j)
 open 2:$j
 use 2
 zwrite
 s result=""
 s lineCount=$select($data(var):$za-1,1:$za-2)
 close 2
 for i=1:1:lineCount s result=result_^SPOOL($j,i)	
 return result
}

You can pass the value to the DTL using the transformation auxiliary parameter, as described in the documentation : Working with Rules | Developing Business Rules | InterSystems IRIS for Health 2023.3.
