问题
I use the Spring Security UI Plugin. I dont want to use the view generated by Spring Security UI, but my own one. Therefore I want to show an error messages in my register/index view. How can I show the error messages in a list?
I would like to have this in my view:
<g:if test="${flash.message}">
<bootstrap:alert class="alert-info">${flash.message}</bootstrap:alert>
</g:if>
When i put this lines there, no error messages are shown. But in the generated register view errors are shown.
When i put down the following code instead:
<g:eachError>
<li>${it}</li>
</g:eachError>
Then I get alot of error messages, but cannot show them in a good way. I even cannot overwrite the messages in internatiolization API:
Field error in object 'xxx.RegisterCommand' on field 'username': rejected value []; codes [x.RegisterCommand.username.blank.error.x.RegisterCommand.username,xxx.RegisterCommand.username.blank.error.username,x.RegisterCommand.username.blank.error.java.lang.String,xxx.RegisterCommand.username.blank.error,registerCommand.username.blank.error.xxx.RegisterCommand.username,registerCommand.username.blank.error.username,registerCommand.username.blank.error.java.lang.String,registerCommand.username.blank.error,xxx.RegisterCommand.username.blank.xxx.RegisterCommand.username,xxx.RegisterCommand.username.blank.username,xxxx.RegisterCommand.username.blank.java.lang.String,xxx.RegisterCommand.username.blank,registerCommand.username.blank.xxx.RegisterCommand.username,registerCommand.username.blank.username,registerCommand.username.blank.java.lang.String,registerCommand.username.blank,blank.xxx.RegisterCommand.username,blank.username,blank.java.lang.String,blank]; arguments [username,class xxx.RegisterCommand]; default message [Die Eigenschaft [{0}] des Typs [{1}] darf nicht leer sein]
I just want to show the errors in a list.
Greetings

Render errors as follow:
<g:eachError>
<li><g:message error="${it}"/></li>
</g:eachError>
