Home Grails 3.3.2: NPE in fields plugin - decapitalizedName?
 I upgraded my app from Grails 3.2.11 to 3.3.2 and went into this issue. I have a class: class Measure { String name Map titles = [:] static hasMany = [ units:Unit ] }  and the scaffolded index.gsp with:   When I try to open the page, I get java.lang.NullPointerException: Cannot get property 'decapitalizedName' on null object at grails.plugin.formfields.FormFieldsTagLib.displayAssociation(FormFieldsTagLib.groovy:815) at grails.plugin.formfields.FormFieldsTagLib.renderDefaultDisplay(FormFieldsTagLib.groovy:770) at grails.plugin.formfields.FormFieldsTagLib.renderDisplayWidget(FormFieldsTagLib.groovy:441) at grails.plugin.formfields.FormFieldsTagLib\$_closure8.doCall(FormFieldsTagLib.groovy:357) I tried to triangulate the problem, and found out that if I remove the titles property from  then it works fine. The show/edit views have no problems displaying the titles prop. Any way to avoid the problem? Shall I file a JIRA?
