textarea $dyn error

[mrzafod]

Hi, I've got a strange behaviour with textarea, see:

textarea.ctr.text(class=UIClass $dyn=UIDynamic)

got console outout

While building the application:
<runJavaScript-34>:506:18: Cannot read property 'length' of undefined (compiling client\ui\ui.jade)

but when I write

textarea.ctr.text(class=UIClass $dyn=UIDynamic)= value
//- or
textarea.ctr.text(class=UIClass $dyn=UIDynamic) Hello hello

got

it seems like textarea doesn't work with dynamic attributes or jade compiler doesn't work right with. You can simply try

//- jade
template(name='testTextarea')
    textarea.ctr.text.white.wide($dyn=testDyn)= testValue

# coffee
Template.testTextarea.helpers
    testDyn: ->
        data = {}
        data['some-attr'] = 'some-attr'
        data['someattr'] = 'some attr'
        data
    testValue: -> 'hello there!'

and you'll get an empty textarea even without classes

works well with v0.2.9

@mquandalle can you look into this? I have a textarea($dyn=atts) {{value}} and $dyn and no attributes are being generated and no errors are produced either. However if I change the textarea to a div attributes are generated. =\

[mquandalle]

@RobertLowe could you please open a new issue?

[michaelevensen]

I'm having the same issue, works perfect for input($dyn=this)

[RobertLowe]

@mquandalle I can create a new issue, but I think it would really be a duplicate of this issue...

@michaelevensen if you need a workaround, use a html template and include it that way, non-optimal though sorry...

[sunstorymvp]

any news here?

all works fine with input, but textarea($dyn=attrs) throws:

Jade syntax error: Cannot read property 'length' of undefined
<runJavaScript-58>:73:14: Cannot read property 'head' of undefined

[dalgard]

I've modified a fork of this package with a new way of writing dynamic attributes, along with a few other useful features. The fork has been released as dalgard:jade.

Would you mind trying out the new package and see if you get the same error?

The new package will be kept in sync with the original, should there be any updates, and generally be maintained until, hopefully, the two packages can be merged.

when will this be fixed?
