Error in Template after newest update

Posted on 03/07/2008 11:04:21

After the newest update I get an error in one of our solutions:

System.NullReferenceException: Object reference not set to an instance of an object. at Dynamicweb.Template.Template(String& strTemplatePath) at Dynamicweb.Template..ctor(String strTemplatePath) at FonqiHelp.FonqiControls.RentaMenu()

The code that produces the error is this:

public static string CreateMenu()
{
    try
    {
        Template t = new Template("RentAMenu.html");
        return t.Output;
    }
    catch (Exception ex)
    {
        return "Menu not generated " + ex.ToString();
    }
}

the Html file is a plain html file with no scripts or nothing spectacular about it.

Is something changed in the way the Dynamic Template class loads a template by Filename?

or what could the error be?

*The solution started failing after the latest DW update.

kind regards Sune Fengel

I have to check up on that.

But you might consider converting it to using the TemplateV2 object instead?

Ok Ill do that from now on but it should not crash all my old solutions where I use the TemplateV1 object. (and it doesnt appear to do so the places where i checked).

No, it seems pretty weird that it happens in only one solution. But the code you provided tells the template object to load the file from the Templates folder. Is this the correct location for the file?

One thing, though. Are there any differences in the request context of the page that fails and those that don't? Could you spot a pattern here?

Well it could be the only place where i call it with a static method.

another thing that could be the issue is if the html document is damaged in some way or access rights are set to not read or whatever.

but the strange thing is that it worked fine until DW rolled out the new updated DLL's.

I got an other reporting on this issue this morning in a project where templates are used in backend. Do you also get the error in backend?

Hi Sune

The error is located. I've mailed you an updated Dynamicweb.dll with a fix. When the fix has been validated to solve the errors it will be released with a DW hotfix.
