grails - Overriding Groovy's java.util.Date toString method -

i have grails (version 2.5.0 ; groovy version 2.4.3) application had custompropertyeditorregistry override date formats when using fieldvalue.

i installed elasticserach grails plugin version 0.0.4.4 , after installation noticed custom property editor not working anymore. in attempt temporarily work around problem, decided override java.util.date's tostring() method using groovy's meta programming.

i added bootstrap.groovy:

date.metaclass.tostring = {    return delegate.format("mm/dd/yyyy hh:mm") } 

however, when went grails console (using grails console plugin):

new date("fri jun 12 12:36:02 edt 2015") string == "fri jun 12 12:36:02 edt 2015" new date("fri jun 12 12:36:02 edt 2015").tostring() == "06/12/2015 12:36"  println(new date("fri jun 12 12:36:02 edt 2015")) // prints fri jun 12 12:36:02 edt 2015 println(new date("fri jun 12 12:36:02 edt 2015").tostring()) // prints 06/12/2015 12:36  

any figuring out custom property issue and/or overriding date tostring() appreciated. have opened issue on elasticsearch grails plugin github, issue #115 well

edit:

i've performed more tests both grails , groovy.

i created new grails 2.5.0 application code in bootstrap.groovy:

date.metaclass.tostring = {     return delegate.format("mm/dd/yyyy hh:mm") } 

and added index.gsp view:

<ul>     <li>new date().tostring() == ${new date().tostring()}</li>     <li>new date() == ${new date()}</li>     <li>new date() string == ${new date() string}</li> </ul>  /*output: new date().tostring() == 06/15/2015 10:32 new date() == mon jun 15 10:32:33 edt 2015 new date() string == mon jun 15 10:32:33 edt 2015 */ 

i launched groovyconsole groovy version 2.4.3 code/output:

date.metaclass.tostring = {     return delegate.format("mm/dd/yyyy hh:mm") }  println(new date()) println(new date() string) println(new date().tostring())  /*output: 06/15/2015 10:38 mon jun 15 10:38:12 edt 2015 mon jun 15 10:38:12 edt 2015 */ 

so appear inconsistency in groovy not calling tostring() modified metaclass method, unless i'm doing incorrectly or misunderstanding something.

you said you're using groovy console, mean you're running grails console, right? bootstrap doesn't run when launching console, in run-app , tests. if run tostring override in console , run sample code should work fine.
