Strange JSX usage compilation error

[Strate]

TypeScript Version: 2.1.0-dev.20160819

Code

Unfortunatelly, I can't extract self-containment example

Expected behavior:
No error

Actual behavior:
Bunch of errors on each JSX usage:

src/lib/components/CTagSelect/CTagSelect.tsx(193,24): error TS2324: Property 'constructor' is missing in type 'IntrinsicAttributes & IntrinsicClassAttributes<CButton> & CButtonProps & { children?: ReactNode; }'.
src/lib/components/CTagSelect/CTagSelect.tsx(193,24): error TS2324: Property 'hasOwnProperty' is missing in type 'IntrinsicAttributes & IntrinsicClassAttributes<CButton> & CButtonProps & { children?: ReactNode; }'.
src/lib/components/CTagSelect/CTagSelect.tsx(193,24): error TS2324: Property 'isPrototypeOf' is missing in type 'IntrinsicAttributes & IntrinsicClassAttributes<CButton> & CButtonProps & { children?: ReactNode; }'.
src/lib/components/CTagSelect/CTagSelect.tsx(193,24): error TS2324: Property 'propertyIsEnumerable' is missing in type 'IntrinsicAttributes & IntrinsicClassAttributes<CButton> & CButtonProps & { children?: ReactNode; }'.
src/lib/components/CTagSelect/CTagSelect.tsx(193,24): error TS2324: Property 'toLocaleString' is missing in type 'IntrinsicAttributes & IntrinsicClassAttributes<CButton> & CButtonProps & { children?: ReactNode; }'.

src/lib/components/CTagSelect/CTagSelect.tsx(193,24): error TS2324: Property 'valueOf' is missing in type 'IntrinsicAttributes & IntrinsicClassAttributes<CButton> & CButtonProps & { children?: ReactNode; }'.

and it happens with almost every component in my project.
Usage of that components does not have spread operator.
I can't extract something special with that components or usage.
It happens only with 2.1 nightly

It really sounds like someone wrote Object in a place where they should have written {}. Can you search your codebase for that type and see if that helps you narrow it down?

@RyanCavanaugh
I am really can't find source of issue and can not reproduce issue on clean project. It happens with only one component, but not with all usages. All failed usages looks likes that:

import {CButton} from "src/lib/components"

class Usage extends React.Component<void, void> {
  render() {
    return <CButton type="type" /* and other attributes with that style, without spread operator */ />
  }
}

Non-failed usages looks like exactly the same :)
Looks like TS treats CButton's properties as an Object, which passes properties from Object.prototype to CButton props.
Object as a type is not used neither in CButton declaration, neither in usage.

Is there some magical logs, which I could enable to catch the issue? :)

[RyanCavanaugh]

What is the declaration of CButton?

[kruczy]

have the same problem when trying 2.1.0-dev.20160831

for me it is only hasOwnProperty missing:
error TS2324: Property 'hasOwnProperty' is missing in type 'CheckboxProps & ComponentProps'.

this is for all usages of Checkbox component and it does not happen for any other component

there is nothing special in the definition of Checkbox it extends the base class the same as everything else and defines an interface for its props

I removed all props from the definition of both CheckboxProps and ComponentProps and it still had the same problem + some bonus ones for not defined props

If I explicitly define props: CheckboxProps directly in Checkbox class it is fine

though if I define the interface to be the same it is coming from generic parent: props: CheckboxProps & ComponentProps; it is also broken

Hope this helps with the issue

I really need some code that reproduces this issue to proceed. Can either of you post a zip or repo link that I can look at?

[Strate]

This issue still reproduces in 2RC.
Unfortunatelly, defining props: CButtonProps directly at CButton does not fixes the issue in my case. Trying to extract self-reproduceable example.

[Strate]

@RyanCavanaugh could you please give me email, where I can send you zip with reproduceable project? Unfortunatelly, I can't share it on github, because it is private.

[Strate]

@RyanCavanaugh I want to ping you, please, give me any email :)

Sorry for the delay, looking now
