Hi! I'm pretty new to Matlab and have my first question after struggling many hours :)

I want to create a custom reporter for my report. I read the documentation for "Define New Reporters" and "Create PDF Document Part Template Library." However, when I generate the report, I only get a blank page.

I added the properties "Title," "Author," and "Version" to "MyTitlePage.m." I unzipped the PDF template default.pdftx, added the required holes to the docpart_templates.html, and zipped it back to default.pdftx.

Which information did I miss or what did i do wrong?

Here ist my short testcode:

Main skript:

import mlreportgen.report.*

rpt = Report("myreport","pdf");

titlePage = MyTitlePage;

titlePage.Title = "Dies ist ein toller Titel";

titlePage.Author = "Me";

titlePage.Version = "1.0";

append(rpt,titlePage);

close(rpt);

rptview(rpt);

docpart_templates.html

<html>

<head>

<title>Document Part Templates</title>

</head>

<body>

</dptemplate>

</dplibrary>

</body>

</html>

Thank you :)

Hello Robert,

I understand that you are encountering an issue where a blank PDF is being generated. This seems to be happening because the "myFirstDocPartTemp" template name specified in the HTML isn't linked to your MyTitlePage.m file.

To resolve this, you should include an additional line in the method:

obj.TemplateName = "myFirstDocPartTemp";

Therefore, the method within your initialization method would be updated to look like this:

    methods 
        function obj = MyTitlePage(varargin) 
            obj = obj@mlreportgen.report.Reporter(varargin{:}); 
                        obj.TemplateName = "myFirstDocPartTemp";
        end 
    end 

If you encounter further issues, please don't hesitate to reach out. After correctly setting the template name in the myTitlePage class, I was able to generate the PDF with the desired outcomes successfully.

For additional information, you might find the following documentation helpful: https://www.mathworks.com/help/rptgen/ug/define-new-types-of-reporters.html#:~:text=obj.TemplateName%20%3D%20%22MyTitlePage%22%3B

I hope this helps!
