Component helper not updating when component name changes
See original GitHub issueI’m upgrading my app from Ember 2.18.2 to 3.1.2 and I’m running into an issue with the component helper and yielding components.
Here is a Twiddle demonstrating the issue. When the Ember dependency is set to 2.18.2 the text changes. When you set Ember to 3.0.0 the text changes. When Ember is set to 3.1.3 the text does not update.
For anyone else running into this issue, Tom Dale provided a workaround in this Twiddle.
Rob Jackson:
Tom and I dug into it a bit and came up with the same work around (using the component helper). The issue comes down to this AST transform completely failing when there are no positional or named arguments to an invocation:

@lifeart - That is a reasonable example test case, but it does not test what this issue is reporting. Another test would need to be added that has an invocation like
{{#let (component this.someThing) as |comp|}}{{comp}}{{/let}}(no other positional or named arguments).Update: I spent some time poking at it but lack the relevant expertise. For the moment, we’re just working around it more.
