问题
I have been trying several solutios for this error, but didn't find any succesful way to overcome this: No provider for TemplateRef!
Error log:
EXCEPTION: Uncaught (in promise): Error: Error in ./FooterComponent class FooterComponent - inline template:15:20 caused by: No provider for TemplateRef! Error: Error in ./FooterComponent class FooterComponent - inline template:15:20 caused by: No provider for TemplateRef!

I tried to do the following:
Research: But only found answers / solutions for templates that actually contain some directives like
ngIf
,ngSwitch
, etc. (Forgetting the*
, for example)Add
TemplateRef
toproviders
. This is what I get:
Argument of type '{ selector: string; templateUrl: string; providers: typeof TemplateRef[]; }' is not assignable to parameter of type 'Component'. Types of property 'providers' are incompatible. Type 'typeof TemplateRef[]' is not assignable to type 'Provider[]'. Type 'typeof TemplateRef' is not assignable to type 'Provider'. Type 'typeof TemplateRef' is not assignable to type 'FactoryProvider'. Property 'provide' is missing in type 'typeof TemplateRef'.
I will try to see how to add somehow TemplateRef
to the app's module providers
. But I don't know if this is the solution.
I hope someone comes out with a solution while I continue researching.
Thank you! :D

missing *
here :
<ul class="dropdown-menu pull-right text-left" dropdownMenu>
should be
<ul class="dropdown-menu pull-right text-left" *dropdownMenu>
From ng2-bootstrap:
<div class="btn-group" dropdown> <button dropdownToggle type="button" class="btn btn-primary dropdown-toggle"> Button dropdown <span class="caret"></span> </button> <ul *dropdownMenu class="dropdown-menu" role="menu"> <li role="menuitem"><a class="dropdown-item" href="#">Action</a></li> <li role="menuitem"><a class="dropdown-item" href="#">Another action</a></li> <li role="menuitem"><a class="dropdown-item" href="#">Something else here</a></li> <li class="divider dropdown-divider"></li> <li role="menuitem"><a class="dropdown-item" href="#">Separated link</a> </li> </ul> </div>
