JsRaw change with Lift 2.5 or Scala 2.10

[Dave Briccetti]

Hi all. I’m finally updating a large project I work on to Lift 2.5 and Scala 2.10. I’m getting quite a few errors like this:

[error]  found   : net.liftweb.http.js.JE.JsRaw

[error]  required: net.liftweb.http.js.JsCmd

[error]   def x = Script(JsRaw("var x = [" +

[David Pollak]

The 2.10 implicit resolution mechanism got changed. The implicit conversion from JsExp to JsCmd sometimes doesn't get picked up. Sigh.

Workaround suggestions? I also get this:

value & is not a member of net.liftweb.http.js.JE.JsRaw

[error]     JsRaw("...") & Foo.method

[error]                  ^

and this:

[error]  found   : net.liftweb.http.js.JE.JsRaw

[error]  required: net.liftweb.http.js.JsCmd

[error]       foldLeft(Noop)(_ & _)

[error]                          ^

iirc, try

myJsRawVal.cmd to make it a JsCmd (adding .cmd)

Thanks

Hi Diego. That seems to be working. Thanks.

Sometimes? At random?

[Dave Briccetti]

Say what? Add .cmd after all my JsRaw(...)s made it work again.

Can someone explain how the implicit resolution changed? Its definitely 2.10.

Just upgraded a project from 2.9_2.5-RC5 to 2.10_2.5-RC5 yesterday and
had to add a few .cmd here and there.

Thanks,
Viktor

Ahh had the same problem and forgot to add a fix (not been doing so much
Lift work lately).

I think the rules have become more strict so if there are multiple
implicit conversions in scope, none will be selected.

And there's a jsExpToJsCmd in both JqJsCmds and JsCmds so if you import
both, you'll get this error.

Yes, it was a bug in older scala versions.

Cool, thanks for the info!
