Exported parameter ValueCheckingMode has or is using private name ('Anonymous class').

On Windows 7, 64-bit (using Node v6.9.0, FF, angular2 v2.23, angular-cli v1.0.0-beta.22-1, typescript v~2.0.3) I get the error message

Exported parameter ValueCheckingMode has or is using private name ('Anonymous class').

when trying to ng serve a project using json2typescript package. Tried it with SALSAH (using json2typescript v0.9.3) and a completely new TestApplication as described in the README here (with latest v0.9.5).

Changing

public static ValueCheckingMode = class {

to

public static ValueCheckingMode: any = class {

did the trick, but I'm not sure whether it is the best possible type nor solution. It's somehow connected to this old TypeScript issue.

On MacOS X (also Node v6.9.0., FF) I could not reproduce this error, it's running without problems.

Have you tried upgrading TypeScript? It seems like this issue is resolved in later versions.

Tested with:
angular-cli 1.0.0-beta.25.5
typescript 2.1.4
json2typescript 0.9.5

Make sure you upgrade angular-cli, because there were issues with TypeScript 2.1.x and earlier angular-cli versions.

Sorry for the late reply, I had to wait upgrading typescript or angular-cli for several reasons. And thanks for the hint, with angular-cli 1.0.0-beta.30.0 I don't get the error anymore.

No worries, thanks for the feedback.
