AOT compilation fails due to private properties

[blagerweij]

[x] bug report

Current behavior
When using angular2-data-table with Just in Time (JiT) compilation it works great, however when trying to use Ahead of Time (AOT) compilation, it fails during compilation.

Root cause:
The data-tables components use private properties, however these properties may be accessed from the template. The properties need to be public.

(from https://medium.com/@isaacplmann/making-your-angular-2-library-statically-analyzable-for-aot-e1c6f3ebedd5):
3. private, protected accessors should be changed to public for any members accessed from template
Error:
Error: Error at /path/to/some.component.ngfactory.ts:134:40: Property 'context' is private and only accessible within class 'SomeComponent'.
Before:
@component({
template: <div> {{ context }} </div>
})
export class SomeComponent {
private context: any;
}

After:
@component({
template: <div> {{ context }} </div>
})
export class SomeComponent {
public context: any;
}

Expected behavior
AOT should be supported

Reproduction of the problem
run 'ngc' on your project with a specific tsconfig.aot.json

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

Please tell us about your environment:
MacOS, ngc, rollup

• Table version: 2.1.3

• Angular version: 2.2.3

• Browser: all

• Language: TypeScript 2.0

Is there a good tool to help do this? @ocombe - u know of anything?

[ocombe]

A tool to help do what ? He's right, properties used in the template have to be public for AoT

[amcdnl]

A tool to do ensure on build AoT is working right.

[ocombe]

I don't, but there is probably one, if you find out let me know.
Check other projects (like material components ? or ng bootstrap ?), how do they check that AoT went well

[ocombe]

So apparently the best way to do it is to build the files, then run the tests with the builded files.

Plz retry on latest :)
