I am computing the doc unid for a document data source. I had some debug print statements and I noticed my code was getting executed four times! Here is the source:

<?xml version="1.0" encoding="UTF-8"?>
<xp:view xmlns:xp="http://www.ibm.com/xsp/core">


<xp:this.data>
<xp:dominoDocument var="course"
formName="Course Information - Info" action="openDocument">

<xp:this.documentId><![CDATA[#{javascript:var ccode = (param.ccode || "");
print("start");
print("course code is " + ccode);
var docUNID = null;
var unid = (param.docid || "");
if (ccode != "") {
server = database.getServer();
catDBName = "admin/courses.nsf";
catDB = session.getDatabase(server, catDBName);
var viewCourseCode = catDB.getView("lookupcoursecode");
var courseDoc:NotesDocument = viewCourseCode.getDocumentByKey(ccode , true);
if (courseDoc != null){
print( "course doc is not null from query open");
var courseDocUNID = courseDoc.getUniversalID();
print("unid is " + courseDocUNID);
docUNID = courseDocUNID;
}
} else if (unid != ""){
print("unid is not null in query open");
docUNID= unid;
}
print("end - returned unid is " + docUNID);

return docUNID;}]]></xp:this.documentId>
<xp:this.databaseName><![CDATA[#{javascript:session.getServerName() +"!!admin\\courses.nsf"}]]></xp:this.databaseName>

</xp:dominoDocument>
</xp:this.data>

</xp:view>

And here is what I see in the console:

Seems like this would be a performance issue?

Re: Computing the document data source unid and the code executes four times!!!!
 Change it to a $ binding (instead of #):
 
 ${javascript:var ccode = (...
 
This will ensure the value is only computed once.
