generate-view ${domainClassWithInURLProperty} 시 Exception

[양완수]

class Book {

   ...

   URL url

   ..

}

Book 을 토대로  generate-view 할 때 

아래와 같은 Exception이 발생합니다.

groovy.lang.MissingPropertyException : URL constraint can only be applied to a String property .....

.....

templates/scaffolding/renderEditor.template 을 살펴보니 아래 cp.url 에서 발생하는것이더군요...(html5 지원을 위한 템플릿 같습니다.)

    private renderStringEditor(domainClass, property) {

        if (!cp) {

            return "<g:textField name=\"${property.name}\" value=\"\${${domainInstance}?.${property.name}}\" />"

        } else {

			def sb = new StringBuilder("")

            if ("textarea" == cp.widget || (cp.maxSize > 250 && !cp.password && !cp.inList)) {

                sb << '<g:textArea name="' << property.name << '"'

 				sb << ' cols="40" rows="5"'

				if (cp.maxSize) sb << ' maxlength="' << cp.maxSize << '"'

				if (isRequired()) sb << ' required=""'

 				sb << ' value="${' << "${domainInstance}?.${property.name}" << '}"'

				sb << '/>'

            } else if (cp.inList) {

				sb << '<g:select name="' << property.name << '"'

				sb << ' from="${' << "${domainInstance}.constraints.${property.name}.inList" << '}"'

				if (isRequired()) sb << ' required=""'

				sb << ' value="${' << "${domainInstance}?.${property.name}" << '}"'

				sb << ' valueMessagePrefix="' << "${domainClass.propertyName}.${property.name}" << '"'

				sb << renderNoSelection(property)

				sb << '/>'

			} else {

				if (cp.password) {

					sb << '<g:field type="password"'

				} else if (cp.url) {

					sb << '<g:field type="url"'

				} else if (cp.email) {

					sb << '<g:field type="email"'

				} else {

					sb << '<g:textField'

				}

				sb << ' name="' << property.name << '"'

				if (cp.maxSize) sb << ' maxlength="' << cp.maxSize << '"'

				if (!cp.editable) sb << ' readonly="readonly"'

				if (cp.matches) sb << ' pattern="${' << "${domainInstance}.constraints.${property.name}.matches" << '}"'

				if (isRequired()) sb << ' required=""'

				sb << ' value="${' << "${domainInstance}?.${property.name}" << '}"'

				sb << '/>'

			}

			sb as String

        }

    }

org.codehaus.groovy.grails.validation.ConstrainedProperty.isUrl 에 따르면  CharSequence.class.isAssignableFrom(propertyType) 이여야 하고 constraint 에 url 설정을 true 해야 되는것 같습니다.

    public boolean isUrl() {

        if (isNotValidStringType()) {

            throw new MissingPropertyException("URL constraint can only be applied to a String property",

                    URL_CONSTRAINT, owningClass);

        }

        return appliedConstraints.containsKey(URL_CONSTRAINT);

    }

겱국 template 상에서 html5 지원 부분 (email,url)체크부분과 if (cp.matches) ... 이 부분을 주석 처리 하였습니다.
