How to show connections in Production Configuration screen for HL7 Router

OnGetConnections() should return an array in the first (Output) argument, indexed by the names of the target process(es) and/or operation(s). The second argument is the production item object passed by the invocation of the method from the web ui.

Here's an example that scans the business process settings for any setting that ends with "ConfigName" or "ConfigNames" and sets the pArray argument appropriately:

ClassMethod OnGetConnections(Output pArray As %String, pItem As Ens.Config.Item)
{
    #dim tSetting As Ens.Config.Setting
    Do ##super(.pArray,pItem)
    For l=1:1:pItem.Settings.Count()
    {
        Set tSetting = pItem.Settings.GetAt(l)
        If ($LOCATE(tSetting.Name,"ConfigNames?$") && pItem.GetModifiedSetting(tSetting.Name,.tValue))
        {
            For i=1:1:$L(tValue,",") 
            {
                Set tOne=$ZStrip($P(tValue,",",i),"<>W")
                Continue:""=tOne
                Set pArray(tOne)=""
            }
        }
    }
}

Adjust the match string in the $LOCATE() function if you're using custom setting name(s) for the target(s).
