> Steps to reproduce:
> In an mx:Form which contains several FormItems whose visibility depends on some logic, when hidden FormItems are displayed the width of the LabelWidth of the Form is not invalidated / recalculated thus truncating the text of the new label (if it's larger than the previously calculated).
> Execute the app below:
> <?xml version="1.0" encoding="utf-8"?>
> <mx:Application
> layout="vertical" minWidth="955" minHeight="600"
> xmlns:mx="http://www.adobe.com/2006/mxml"
> xmlns:local="*"
> xmlns:containers="mx.containers.*">
> <containers:MyForm id="form"
> width="300">
> <mx:FormItem
> width="100%"
> label="My label">
> <mx:TextInput width="100%"/>
> </mx:FormItem>
> <mx:FormItem id="fi"
> width="100%"
> label="My label long" includeInLayout="{v.selected}"
> visible="{v.selected}">
> <mx:TextInput width="100%"/>
> </mx:FormItem>
> </containers:MyForm>
> <mx:CheckBox id="v"/>
> </mx:Application>
> Actual Results:
> When selecting / unselecting the checkbox, the second FormItem appears but the text is truncated.
>
> Expected Results
> The label should be resized.
>
> Workaround (if any):
> There at least a couple of workarounds:
> 1. Invoke form.styleChanged(null). This will cause invalidateLabelWidth to be invoked
> 2. Create a subclass of mx:Form in the mx.containers package. Create a public method on it to proxy calls to invalidateLabelWidth. Invoke the public method when needed
