componenta:

@component({   selector: 'component-a'   , directives: [     form_directives     , componentb   ]   , template: `     <!-- works --><component-b [(ngformcontrol)]="_formcontrol"></component-b>     <!-- fails --><component-b *ngfor="#number of numbers" [(ngformcontrol)]="_formcontrols[number]"></component-b>   ` })  export class componenta {}

any hints/help highly appreciated.

as suggested @tylerdurden

this error message produced bug introduced in cycle detection (see #6404).

there's fix in master (see #6474) not yet released. sure in beta.2.

the recommendation downgrade beta.0 until storm over.

update

this issue has been fixed in beta.2 (issues minification still there). see changelog more details.
