AjaxRadio

[Julio]

Hello Everyone,

I was successfully able to implement an ajaxRadio example with simple css-sel binding. 

My problem is that I don't know what will be the radio options during page load, only after an ajaxSubmit returns a parameter that will be used to generate the options.

What is the easiest way to bind ajaxRadios after page load?

Thank you, Julio

Hi try the following

Mariano,

Thank you! idMemoize is what I needed.

Is it possible to bind a ChoiceHolder instead of a ChoiceItem? I have an unknown amount of options. I was able to prepend radio options via JsCmd with ajax working, but lift's wiring would not work.

Thank you, Julio

[Mariano Lucchetta]

You can call .toForm method from ChoiceHolder.

Mariano,

I tried that but wiring does not work. I'll try to post a sample.

Thank you, Julio

I figured the problem was I did something wrong with wiring and apparently I did.

val hello = ValueCell("")
val place = ValueCell("")

val msg = hello.lift{h =>  s"${h} ${place}"} // prints Hello ValueCell() (although using valuecell to print value is suggested: http://simply.liftweb.net/index-6.1.html#toc-Section-6.1)

Tried these but nothing.
val msg = hello.lift{h => place.lift{p => s"${h} ${p}"}} // prints FuncCell1(ValueCell(),<function1>)
val msg = hello.lift{h =>  s"${h} ${place.get}"} // prints Hello World (but place radio group does not update properly)

What's the right way of assigning a FuncCell to 2 ValueCells?

Hey Julio - what effect are you trying to achieve? I can't figure it out from your question.

Any hints?

I'm trying to concatenate 2 valuecell strings with Lift's Wiring.

Yes, That works. Thank you. I wasn't aware you could use the lift method like that.
