Making joda.DateTime a searchable property in grails

I am using the joda time library in my grails project. I've installed the searchable plugin. I have a few domains but the most important now :

import org.joda.time.DateTime

class Entry {

     static searchable = {
     except = ['id', 'version']
     spellCheck "include"
     tags component: true

     title boost: 2.0
        dateCreated boost: 2.0
     }

 String title
 String content
 DateTime dateCreated
 DateTime lastUpdated

}

But on initialization I encounter the following error:

Unable to map [Entry.dateCreated]. It does not appear to a suitable 'searchable property' (normally simple types like Strings, Dates, Numbers, etc), 'searchable reference' (normally another domain class) or 'searchable component' (normally another domain class defined as a component, using the 'embedded' declaration). Is it a derived property (a getter method with no equivalent field) defined with 'def'? Try defining it with a more specific return type

My question: Is it possible to make the dateCreated and/or lastUpdated properties searchable in grails? If possible, how can this be done?

Thanks.

EDIT

If I was to define a custom converter in my config.groovy like so:

Map compassSettings = [ 'compass.converter. funkyConverter.type':'com.acme.compass.converter.FunkyConverter']

What is then defined in the FunkyConverter class?

The version of compass that came with version 0.6 of Searchable (any maybe earlier versions) had some special case code in it (in class org.compass.core.converter.DefaultConverterLookup) for the org.joda.time.DateTime class. I can't speak directly to whether it works or not, but it looked like it would try to automatically make use of org.compass.core.converter.extended.DataTimeConverter included in Compass for the joda DateTime class.

However, for joda LocalDate and LocalTime classes, there was no built-in support. A recent bug fix to Searchable version 0.6.1 ( http://jira.grails.org/browse/GPSEARCHABLE-28 ) along with the use of the registerClass configuration in Searchable.groovy shown below has fixed my "It does not appear to a suitable 'searchable property'..." problem that was occurring at application startup while domain objects were being instantiated in Bootstrap.groovy.

compassSettings = [
    "compass.converter.jodatime.type": "net.streamrecorder.web.converter.LocalTimeConverter",
    "compass.converter.jodatime.registerClass": "org.joda.time.LocalTime"
]

Note that net.streamrecorder.web.converter.LocalTimeConverter is my own creation. I modeled it after org.compass.core.converter.extended.DataTimeConverter. There is also a converter for LocalDate in this diff referenced from the GPSEARCHABLE-28 ticket: ( http://jira.grails.org/secure/attachment/15729/0001-Nasty-fixes-and-workarounds-for-adding-custom-compas.patch ) And of course, you still need to specify your converter for your domain member variable in your domain class as described here: ( http://grails.org/Searchable+Plugin+-+Converters )
