Hi

After updating to Typescript 2.2.2, all HTML templates using a pipe show an error marker. This applies to both, built-in and custom pipes, respectively.

@Typescript 2.2.x
When using a pipe the editor complains with the following error: Unable to resolve signature for pipe invocation. [1]
Also, when hitting the F3 key to open the pipe’s definition, an internal error is raised. [2]

@Typescript 2.1.6
Pipe resolution works as expected, meaning no error in the problems view and the pipe declaration can be opened.

Best Regards,
Daniel

@Sten,

did you do a Project – Clean after updating Webclipse?
This helped for me. Also make sure your Pipe is actually accessable / runnable by running an NG serve ignoring the error shown. -> does this work for you?

Regards
Jan

[Sten]

Thx Jan,

yes I tried to clean the project(s)! That did not help.

All my pipes are working as expected when testing with ng serve.
It is just an eclipse/webclipse problem.

[Jan]

Hm ok, to bad 🙁

This is how I created my pipe, maybe you spot a difference there, even if your pipe works?
Maybe we can narrow down the parsing issue.

@Pipe({
  name: 'slackemoji'
})
export class SlackemojiPipe implements PipeTransform {...}

registered using a provider:
providers: [SlackemojiPipe],

Cheers
Jan

Sten,

Can you provide full code of the pipe excluding method bodies? And please share the template part where you use the pipe. It looks like there is some typing issue in your definition.

Best regards,
Piotr Tomiak

Sure here you go, for me the pipe issue has been fixed however:

import { Pipe, PipeTransform } from '@angular/core';
import { DomSanitizer } from '@angular/platform-browser';

@Pipe({
  name: 'slackemoji'
})
export class SlackemojiPipe implements PipeTransform {

  constructor(private _sanitizer: DomSanitizer) { }

  transform(value: any, args: any[] = []) {
    return this._sanitizer.bypassSecurityTrustHtml(value);
  }
  escapeRegExp(str) {
  }
  replaceURLWithHTMLLinks(text) {
  }
  replaceMailToReference(text) {
  }
  replaceSlackReference(text) {
  }

}

@Component({
  selector: 'xxx',
  templateUrl: './question.component.html',
  styleUrls: ['./question.component.css'],
  providers: [SlackemojiPipe],
})

using the pipe:

<div class="card card-block bg-faded qna-box">
					<div class="message-container"
						[innerHTML]="wsElement.content.content | slackemoji"></div>
				</div>

Happy hunting 🙂
