sys::Obj
  afFormBean::SkinCtx

Passed to InputSkins to provide all the information they need to render a form field.

bean

Obj? bean { internal set }

The bean instance being rendered.

beanInvalid

Bool beanInvalid()

Returns true if the bean is invalid; that is, if any field is in error.

Convenience for formBean.hasErrors().

errMsg

Str? errMsg

Convenience for FormField.errMsg.

The error message associated with this field.

Setting this to a non-null value invalidate the form field.

field

const Field field

The corresponding bean field.

fieldInvalid

Bool fieldInvalid

Convenience for FormField.invalid.

Returns true if the form field is invalid. Note that just because the field is invalid, it does not mean it has an error message.

Setting this to false also clears any errMsg.

fieldValue

Obj? fieldValue()

Returns the field value.

formBean

FormBean formBean { internal set }

The containing FormBean instance.

formField

FormField formField { internal set }

The FormField being rendered.

id

Str id()

Convenience for field.name plus any unique ID suffix defined by the FormBean.

label

Str label()

Returns the preferred display label associated with the field.

msg

Str? msg(Str key, Obj? arg1 := null, Obj? arg2 := null, Obj? arg3 := null)

Convenience for FormField.msg.

Returns a message for the given field. Messages are looked up in the following order:

<bean>.<field>.<key>
<field>.<key>
<key>

And the following substitutions are made:

${label} -> formField.label
${value} -> formField.formValue
${arg1} -> arg1.toStr
${arg2} -> arg2.toStr
${arg3} -> arg3.toStr

The form value is substituted for ${value} because it is intended for use by validation msgs.

Returns null if a msg could not be found.

name

Str name()

Convenience for field.name and used as the form name. Also safe for use as a CSS class name.

renderAttributes

Str renderAttributes([Str:Str]? extraAttributes := null)

Returns a rendered string of common attributes to be placed in the <input> HTML tag. This includes id, name and any validation attributes defined on the HtmlInput facet.

Note the string does not contain the type or value attributes as these are dependent on the input type.

The given extraAttributes are merged in, with any values of the same name being separated with a space. This allows you to pass in extra css class names.

attrs := skinCtx.renderAttributes(["data-foo" : "bar", "css" : "funkStyle"])

Note that empty string values are rendered as HTML5 empty attributes. e.g. ["disabled":""] would be rendered as just disabled.

toClient

Str toClient(Obj? value)

Convenience for formField.toClient().

Converts the given value to a string using the preferred ValueEncoder.

value

Str value()

Returns the preferred string value to be rendered in the <input>.
