Error with Grails Spring Security UI Plugin when creating new user - Error Processing GroovyPageView

[mickdavis]

I'm getting the following error using the Spring Security UI Plugin when I click on the link to create a new user:

"Error processing GroovyPageView: Error executing tag <s2ui:form>: Error executing tag <s2ui:tabs>: Error executing tag <s2ui:tab>: Error executing tag <s2ui:textFieldRow>: assert beanType | null"

I'm running Grails 2.5.5 with SpringSecurityCore 2.0.0 and SpringSecurityUI 1.0-RC3. I have not customized anything about the plugins.

Everything was working fine for several days. I'm able to create Roles, I can search for and edit Users. Everything except the ability to create a new User. I've spent over 8 hours trying to debug this.

Here's the trace:

Any help would be greatly appreciated. Sorry in advance if this is hard to read, I've never posted anything here before.

Thanks in advance.

By major coincidence, I ran into the exact same issue with the exact same versions of grails and the two plugins today. @mickdavis: I feel your pain.

[marvinthepa]

I think I found the issue. Spring-security-ui does not like it when the "Person" and "Role" domain objects (see http://grails-plugins.github.io/grails-spring-security-core/v2/guide/domainClasses.html#personClass) return null in their "toString" methods.

So my solution was to change

    String toString() {
        return this.username
    }

to

    String toString() {
        return this.username ?: 'Person without username'
    }

(this is for the Person class, but I had to update the Role class accordingly).

Btw. I think the issue is still a bug in spring-security-ui, I will probably create a pull request soon.

@marvinthepa - your patch - can't get it working.

Can't get an override - I'll need to rebuild the entire plugin and use that one from a local repo vs just being able to override it somehow?

Was also trying to get my subclassed usercontroller to work in a namespace, but if the namespace is different from the parent class, that seems like it won't work either... (or would it?)

(the toString() stuff didn't work for me, unfortunately)

Thanks for your potential patch :)

[marvinthepa]

@mgkimsal: I don't know if you can override taglibs. Building the plugin yourself from source will definitely work.

If fixing your toString in your person and role domain objects didn't help, I suspect you are experiencing a different problem. I might be able to tell if you share the stacktrace that you see.

@mickdavis @marvinthepa
I have been unable to reproduce this issue with:

compile "org.grails.plugins:spring-security-core:2.0.0"
compile "org.grails.plugins:spring-security-ui:1.0-RC3"

using grails-2.5.6 and java 8u144-zulu

Here's a link to a video demonstrating it working:

and here's the test app I created:
security-ui_issue-56.zip

Are you able to provide a test app which reproduces the issue?

Thanks!

@ddelponte:

to reproduce this with your example, you have to add a toString method that may return null, as mentioned in #56 (comment):

diff --git a/grails-app/domain/com/testapp/User.groovy b/grails-app/domain/com/testapp/User.groovy
index aacd5d0..235d48c 100644

 }

Thanks @ddelponte for fixing this
