NGC compilation error with 2.3.0

[sluglit]

When compiling with @angular/[email protected]
I get the following error:

Error: Error encountered resolving symbol values statically. Only initialized variables and constants can be referenced because the value of this variable is needed by the template compiler (position 7:12 in the original .ts file), resolving symbol Ng2BootstrapConfig in c:/project/node_modules/ng2-bootstrap/components/ng2-bootstrap-config.d.ts, resolving symbol TypeaheadContainerComponent in c:/project/node_modules/ng2-bootstrap/components/typeahead/typeahead-container.component.d.ts, resolving symbol TypeaheadContainerComponent in c:/project/node_modules/ng2-bootstrap/components/typeahead/typeahead-container.component.d.ts

This is caused by the ng2-bootstrap-config.ts code static variable and that aren't initialized.

I also get this problem. Angular 2.3.0. Typescript 2.0.10. My workaround was to revert to Angular 2.2.0.

[valorkin]

this is awesome, so you just need to set default value
@sluglit this is a perfect chance for small PR ;)

[sluglit]

@valorkin It isn't that simple.
I tried to fix the code on my cloned repo, and it seems to be an issue with the way angular-cli pre-compiles static methods and variables.

To resolve this we will have to get rid of the static declarations and make this class instance based (instead of calling the methods statically)

Then to make the class behave the same, we will have to inject the instance into the NgModule in provided.

I will play with that approach and if it work's; I'll raise a PR.

[valorkin]

omfg ... this sounds as a bad news
but you can try simply export function
it will static for module (file module level)

@sluglit @valorkin any progress on this?
This bug is currently preventing me from compiling my project at work, and I cannot revert Angular back to 2.2.0 either because that gives me other errors, so I'm kinda stuck.

[tsoposki]

@linusbrolin Try revert Angular back to "2.2.4". I am using that version and I don't have any issue.

[linusbrolin]

@tsoposki Thanks! That specific version seemed to not produce error messages.
Now I can continue my work. phew ;)

[valorkin]

There are v1.1.16-4, who can try it with ng v2.3
I would really appreciate it

[tsoposki]

@valorkin I tried with ng2 "2.3.0" and "2.3.1" with the latest ng2-bootstrap "1.1.16-4" and I am still getting the same issue.

[valorkin]

please try v1.1.16-5

[valorkin]

I will reopen issue, until fix confirmed
DM me here if anything https://ngx-slack.herokuapp.com/

[valorkin]

Please confirm that issue is fixed in v1.1.16-6

[sluglit]

Hi Valorkin
With 1.1.16-6 I get the following error.

Error at D:/project/node_modules/ng2-bootstrap/typeahead/typeahead-c
ontainer.component.ngfactory.ts:167:44: Property 'isBs4' does not exist on type 'TypeaheadContainerComponent'.

FYI: I am working on a PR but it's taking a while...

[valorkin]

ok, check v1.1.16-7
I don't know WHY, in prev build it is just skipped variable

[sluglit]

Thanks for the work you put in, version 1.1.16-7 works with angular 2.3.1.
(Probably for 2.3.0 too)

[valorkin]

awesome, back to docs ;)
BTW I am planing to add spec to each demo sample,
would it make sense?

[sluglit]

I believe that it would help, it would effectively be your e2e tests.
