Throwing error in AoT production build

[shreekantha]

I am using Angular CLI, when I try to build app with command "ng build --prod --aot", it started throwing error.

ERROR in Error encountered resolving symbol values statically. Calling function 'makeDecorator',
function calls are not supported. Consider replacing the function or lambda with a reference to a
n exported function, resolving symbol Injectable in /home/spaneos/Videos/ng2aot/node_modules/angu

Please help me on this. We are going to production in next week.

Are you sure it's related to this component? I ran "ng build --prod --aot" just a while ago with the latest version and no issues.

[shreekantha]

Yes it is related to multi select drop down only and I am not using any other third party libraries except multi select drop down.

@shreekantha, why are you certain it is because of this library?

Have you tried running the build process with and without the package included?

[shreekantha]

Yes I tried , without this package, project is built successfully.

@softsimon , please help me to resolve this issue.

[shreekantha]

@softsimon, Issue has been resolved.
I forked your project and moved all dependencies into devDependencies in package.json.
I did npm pack and installed package into project, then I built using "ng build --prod --aot".
Project built successfully .

I committed the changes into GitHub

[shreekantha]

@softsimon , It will be great help for me if you can re-publish your project to npm, so that we can use in our project to build in AoT.

I forked and I did necessary changes that are required for AoT build, If you feel its useful than you can merge my commit into your master branch.

Awaiting your response

Thank you so much for this fantastic multi select library.

@shreekantha I can do it tonight. Can you make a pull request in the meantime? Otherwise I'll just grab the code ;-)
