Grails select won't display string from nested class

I'm trying to do something pretty simple, that apparently is not that simple. I have a domain class:

class Regex {
    String name
    String Regex 
}

and another class:

class RegexRef {
    int sequenceNumber
    Product product
    Regex regex
}

Now, in a select, I want to list the RegexRef instances, with the name of the regex as the optionValue as such:

<g:select name="regexRef.id" from="${com.mycompany.RegexRef.list()}" optionKey="id" size="5" optionValue="regex.name" value="${actionRefInstance?.regexRef?.id}"  />

but this doesn't work. It throws: Exception Message: No such property: regex.name for class: com.jetheaddev.RegexRef

I can do this mis-direction in other constructs...

<g:link controller="regexRef" action="show" id="${actionRefInstance?.regexRef?.id}">${actionRefInstance?.regexRef?.regex.name.encodeAsHTML()}</g:link>

and it works fine.

With optionValue="regex.name" the <g:select/> is trying to retrieve the property of RegexRef as:

regexRefInstance."regex.name"

To retrieve the name property on the Regex class do:

<g:select optionValue="${{it.regex.name}}"/>

which will run the optionValue Closure on each entry in the list and retrieve the related name property.
