It seems that ng-content replacement does not work for elements selected by element name, after RC6

[x ] bug report

Current behavior It seems that ng-content replacement behaviour is broken on RC-6 for elements selected by element name, for example:

<ng-content select="element-name"></ng-content>

But works for

<ng-content select=".class-name"></ng-content>

Sample error message:

'modal-content' is not a known element:
1. If 'modal-content' is an Angular component, then verify that it is part of this module.
2. If 'modal-content' is a Web Component then add "CUSTOM_ELEMENTS_SCHEMA" to the '@NgModule.schema' of this component to suppress this message. ("-modal title="Incluir grupo econômico" #addCustGroupDialog [approve]="approveNewCustomerGroup">
    [ERROR ->]<modal-content>
      <div class="ui fluid input">
        <input class="ui input" type="text" [(ngMo"): CustomerGroups@6:4

Expected/desired behavior Normal behaviour verified before RC6. As described in this article: https://toddmotto.com/transclusion-in-angular-2-with-ng-content

Reproduction of the problem https://plnkr.co/edit/K1UYuVEMyxmMIhmWz4nl?p=preview

What is the expected behavior? Normal behaviour verified before RC6.

What is the motivation / use case for changing the behavior?

Please tell us about your environment:

• Angular version: 2.0.0-rc.6
• Browser: [Chrome 52, Firefox 48.0.2]
• Language: [TypeScript]

I suppose the compiler could see the <ng-content select="X"...> and let the 'X` tags through the element check when used in that context (and that context only).

That seems plausible. Maybe we should consider that idea. I’ll run it by some people.

Seems like your errors is:

'modal-content' is not a known element:
1. If 'modal-content' is an Angular component, then verify that it is part of this module.
2. If 'modal-content' is a Web Component then add "CUSTOM_ELEMENTS_SCHEMA" to the '@NgModule.schema' of this component to suppress this message. ("-modal title="Incluir grupo econômico" #addCustGroupDialog [approve]="approveNewCustomerGroup">
    [ERROR ->]<modal-content>
      <div class="ui fluid input">
        <input class="ui input" type="text" [(ngMo"): CustomerGroups@6:4

if <modal-content> is an angular cmp, is should be in your test modules includes
