Hi all,

When making a Business Process reusable, I needed to make the target of a <call> configurable as a business host setting. This can be done through indirection. Here's how:

Property TargetConfigName As Ens.DataType.ConfigName;

Parameter SETTINGS = "TargetConfigName:Basic";

/// BPL Definition
XData BPL [ XMLNamespace = "http://www.intersystems.com/bpl" ]
{
<process language='objectscript' request='Ens.Request' response='Ens.Response' height='2000' width='2000' >
<sequence xend='200' yend='450' >
<call name='Call configurable target' target='@process.TargetConfigName' async='1' xpos='200' ypos='250' >
<request type='Ens.Request' >
<assign property="callrequest" value="request" action="set" />
</request>
<response type='Ens.Response' >
<assign property="response" value="callresponse" action="set" />
</response>
</call>
<sync name='Wait' calls='Call configurable target' type='all' xpos='200' ypos='350' />
</sequence>
</process>
}

/// Return an array of connections for drawing lines on the config diagram ClassMethod OnGetConnections(Output pArray As %String, pItem As Ens.Config.Item) { Do ##super(.pArray,pItem) If pItem.GetModifiedSetting("TargetConfigNames",.tValue) { For i=1:1:$L(tValue,",") { Set tOne=$ZStrip($P(tValue,",",i),"<>W") Continue:""=tOne Set pArray(tOne)="" } } }

Hi @Otto Medin
very good point.

In order to get links visible on the production configuration, you can add this method :

/// Return an array of connections for drawing lines on the config diagram
ClassMethod OnGetConnections(Output pArray As %String, pItem As Ens.Config.Item)
{
	Do ##super(.pArray,pItem)
	If pItem.GetModifiedSetting("TargetConfigNames",.tValue) {
		For i=1:1:$L(tValue,",") { Set tOne=$ZStrip($P(tValue,",",i),"<>W")  Continue:""=tOne  Set pArray(tOne)="" }
	}
}ObjectScript
