Template not being displayed

[helmut2509]

Hello,

I have a template (mytpl) to which I assigned an Alternate Template File (mainTpl) which contains the business logic.

From there I call /templates/views/mytpl.php . Now I have the impression there is something messed up:

suddenly the template only delivers a blank page.

So I inserted a debug message in wire/core/TemplateFile, function __render: echo "out = $out" (just before return) and saw that there is a double output which

however is not being displayed without the debug message.

How can I fix this? 

Can I have view templates without declaring them as pw-templates, just calling them from the mainTpl?
