I have upgraded to spring boot 1.3.5.RELEASE in the fork
https://github.com/arcadius/light-admin
and it builds well and all tests pass.

Now, I am trying the lightadmin-springboot application using the new build light-admin-1.3.0.BUILD-SNAPSHOT and boot 1.3.5
Code is at https://github.com/arcadius/lightadmin-springboot
ran it using gradle clean bootRun

I could login successfully, but when I click on the "Cities" navigation on the left hand side, I get

[ERROR] org.apache.catalina.core.ContainerBase.[Tomcat].[localhost].[/].[lightadmin-dispatcher] - Servlet.service() for servlet [lightadmin-dispatcher] in context with path [] threw exception [Request processing failed; nested exception is org.springframework.http.converter.HttpMessageNotWritableException: Could not write content: (was java.lang.NullPointerException) (through reference chain: org.springframework.hateoas.PagedResources["_embedded"]->java.util.UnmodifiableMap["persistentEntityWrappers"]->java.util.ArrayList[0]); nested exception is com.fasterxml.jackson.databind.JsonMappingException: (was java.lang.NullPointerException) (through reference chain: org.springframework.hateoas.PagedResources["_embedded"]->java.util.UnmodifiableMap["persistentEntityWrappers"]->java.util.ArrayList[0])] with root cause

Debugging this led me to spring source code PersistentEntityJackson2Module where we have

public Links getLinksFor(Object object, List<Link> existingLinks) {

            Assert.notNull(object, "Object must not be null!");
            Assert.notNull(existingLinks, "Existing links must not be null!");

            PersistentEntity<?, ?> entity = entities.getPersistentEntity(object.getClass());

        ...

The issue is caused by object.getClass() returning PersistentEntityWrapper instead of City .
Spring is expecting the real class and not the wrapper.

I wonder whether you @max-dev , @jerryrt or @lazaridis-com have an idea of what I may be doing wrong.

Thank you very much.

Hi Arcadius,

I changed this behaviour with the following commit:
nmeierling/light-admin@9bc96d4

Now the exception is not thrown any more. Nevertheless LA does not seem too work yet. It shows the correct count of items ( "All(3)" ), but not the item rows themselves. Since I havent had a proper running LA, I cannot estimate if these are due to my changes or not. I'll keep you posted if I find more.

Is there any progress on supporting Spring Boot 1.3.4+?

@nielsmite All of the js code should be updated as the json now is not based on the wrapper, but the real entity instead.
