documentId resolving code doesn't get executed XPages

Question

In my XPage I need to set a data source (Domino document)

I try to do it as follows:

<xp:this.data>
    <xp:dominoDocument var="requestDocument" action="openDocument" databaseName="#{javascript:  print('db ok'); return database.getFilePath();}"
        documentId="#{javascript:
        print('heloooo');
           var conclusion = database.getDocumentByUNID(doc_source.getDocument().getParentDocumentUNID());
           var oConclusion = new OsnovaUI_document(conclusion);
           var requestDoc = oConclusion.getMainDocument();

           print('docID: ' + requestDoc.getUniversalID());

           return requestDoc.getUniversalID();
           }">

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

The thing I've noticed is that code section in documentId doesn't get executed. At all. That's why I've put heloooo in there. However, the databaseName works as expected. In console I always see

09.03.2020 00:52:11   HTTP JVM: db ok

But not heloooo :(

What am I doing wrong? Thanks in advance

The most likely cause is ignoreRequestParams is not set to true. Unless you set that, the data source is retrieving all specifics about which document to edit based on the URL query string parameters (the HTTP request parameters). As a result, the URL query string parameters take precedence, and in the case of nothing being set, that means "use a new document". If you've defined that the URL query string parameters should take precedence, running your code to merely ignore it afterwards is inefficient. As a result, action="openDocument" is also being ignored - if you have a docId in the query string it will open that, otherwise it will create a new document.

documentId can only get processed once, when the page first loads. Depending on whether the datasource is bound to a panel or an XPage / Custom Control, it will run before the beforePageLoad event as well. So runtime binding (#{javascript:...) has no effect. ${javascript:... will avoid confusion.

Error handling may help identify if there is an error. XPages OpenLog Logger is one of the most pervasive (disclaimer, I'm the author) https://openntf.org/main.nsf/project.xsp?r=project/XPages%20OpenLog%20Logger.
