FormBuilderLocator and generic types

[Peter Brant]

Hi all,

I'm trying to register a custom FormBuilderLocator for a generic type.

Boot.scala has this

LiftRules.prependGlobalFormBuilder(FormBuilderLocator[FormValue[CaseNo]]((value,
setter) =>
SHtml.text(value.asString, s => setter(new FormValue[CaseNo](s)))))

My screen object has this

val caseNo = field("Case No", new FormValue[CaseNo], valConversion)

The part that I don't understand is that the FormBuilderLocator is
registered under the string key

gov.wicourts.jdash2.form.FormValue[gov.wicourts.jdash2.lib.CaseNo]

but vendForm() is looking for a FormBuilderLocator under the string key

gov.wicourts.jdash2.form.FormValue[_ <: gov.wicourts.jdash2.lib.CaseNo]

The other odd thing is that FormValue[String] works fine. I thought
maybe this was because String is final, but that doesn't seem to
matter.

Does anybody have any ideas how to make this work?

Thanks much,

Pete

I don't understand it either. :-(

just for kicks try:

val caseNo = field[FormValue[CaseNo]](....)

If that works, woo hoo.  If it doesn't let's do some more digging.

Also, if you can put together a small example of the issue (see Posting example code | Lift Space | Assembla ), please open a ticket on the issue (http://ticket.liftweb.net you must be a watcher of the LiftWeb space on Assembla) and we'll make it easier for the next person.

Oh, do you still want a sample project and issue for this (which I'm
happy to provide if you want)?

It would be helpful to have the example and a ticket.  The Lift for Scala 2.7.7 code has to use String because Manifest was not comparable.  Scala 2.8.0+ supports comparable manifests and I'd like to switch over to that mechanism and also make things much more sane for folks using Screen/Wizard.

Thanks!

Well, maybe it is. :-) I'll add the ticket tomorrow.

Hmm... sorry if this comes through twice, but I would have expected
this to have shown up by now.

In any case, ticket is here

Thanks for the ticket.  New posters are moderated... mainly to avoid spam/porn on the list and it happens that moderators are not always moderating 24/7. ;-)
