You need to specify the value attribute in this tag. http://grails.org/doc/2.0.x/ref/Tags/select.html

So in your example,

<g:select ... value="${com.springcommunity.fleet.partymodel.roles.ClientRole.get(2)}" />

One thing to be aware of here is that the value that you’re selecting must be an object equal to the item in the list, and not just an id – this is where a lot of people get tripped up. So you can’t just say value=’2′, you need to specify the object in the list that you have in your from attribute.

From the docs –

value (optional) – The current selected value that evaluates equals()
to true for one of the elements in the from list.
