If one defines a range constraint on a domain object property with a large number (e.g. 1..1000000) the scaffolding mechanism generates with the create view a <g:select> tag <tr class="prop"> <td valign="top" class="name"> <label for="price">Price:</label> </td> <td valign="top" class="value ${hasErrors(bean:giftItem,field:'price','errors')}"> <g:select from="${0..1000000}" id="price" name="price" value="${giftItem?.price}" ></g:select> </td> </tr> It seems that this tag is somehow not able to handle this large range appropriate and causes the OutOfMemoryException. Reproduction instructions: ----------------------------------- 1. Create grails app 2. Drop domain object (see attachment) into domain folder 3. run grails generate-all for each domain object 4. start grails app 5. call http://localhost:8080/<app-name>/giftItem/create Stacktrace -------------- java.lang.OutOfMemoryError: Java heap space at java.util.Arrays.copyOf(Arrays.java:2882) at java.lang.AbstractStringBuilder.expandCapacity(AbstractStringBuilder.java:100) at java.lang.AbstractStringBuilder.append(AbstractStringBuilder.java:390) at java.lang.StringBuffer.append(StringBuffer.java:224) at java.io.StringWriter.write(StringWriter.java:95) at java.io.PrintWriter.write(PrintWriter.java:412) at java.io.PrintWriter.write(PrintWriter.java:429) at org.codehaus.groovy.grails.web.taglib.GroovyPageTagWriter.write(GroovyPageTagWriter.java:57) at org.codehaus.groovy.runtime.InvokerHelper.write(InvokerHelper.java:477) at org.codehaus.groovy.runtime.DefaultGroovyMethods.leftShift(DefaultGroovyMethods.java:3916) at sun.reflect.GeneratedMethodAccessor59.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.codehaus.groovy.runtime.metaclass.ReflectionMetaMethod.invoke(ReflectionMetaMethod.java:51) at org.codehaus.groovy.runtime.metaclass.NewInstanceMetaMethod.invoke(NewInstanceMetaMethod.java:54) at groovy.lang.MetaMethod.doMethodInvoke(MetaMethod.java:226) at groovy.lang.MetaClassImpl.invokeMethod(MetaClassImpl.java:899) at groovy.lang.ExpandoMetaClass.invokeMethod(ExpandoMetaClass.java:946) at groovy.lang.MetaClassImpl.invokeMethod(MetaClassImpl.java:740) at org.codehaus.groovy.runtime.InvokerHelper.invokePojoMethod(InvokerHelper.java:765) at org.codehaus.groovy.runtime.InvokerHelper.invokeMethod(InvokerHelper.java:753) at org.codehaus.groovy.runtime.ScriptBytecodeAdapter.invokeMethodN(ScriptBytecodeAdapter.java:167) at org.codehaus.groovy.grails.plugins.web.taglib.FormTagLib$_closure16_closure25.doCall(FormTagLib.groovy:556) at sun.reflect.GeneratedMethodAccessor176.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.codehaus.groovy.reflection.CachedMethod.invoke(CachedMethod.java:86) at groovy.lang.MetaMethod.doMethodInvoke(MetaMethod.java:226) at groovy.lang.MetaClassImpl.invokeMethod(MetaClassImpl.java:899) at groovy.lang.ExpandoMetaClass.invokeMethod(ExpandoMetaClass.java:946) at groovy.lang.MetaClassImpl.invokeMethod(MetaClassImpl.java:740) at groovy.lang.Closure.call(Closure.java:292)
