DynamicList returns list of entities with null values

[sudhakhayal]

Originally, I had extended DynamicList<FAQs, SimpleBrokerQuery> from my custom model FAQsContentList where I want to execute a SimpleBrokerQuery on a few filterKeywords. In the logs I can see that I get query results but when it goes through the default Model Builder, the entity returns n results with null values. Originally I get a list of entity objects but with null values c.s.d.t.m.impl.DefaultModelBuilder - Expected class is pre-set to class com.sdl.dxa.modules.faqs.model.FAQs for model EntityModelData(id=4979, componentTemplate=null, linkUrl=null, content=null, binaryContent=null, externalContent=null)

Now, I get the another error (shown below) when I played around with the template, but the bottom issue is that I am not getting any field values. FAQs schema comes under module FAQs and my DynamicList is under another module ContentList.

The exception is .api.mapping.semantic.SemanticMappingException: Ambiguous semantic mapping for http://www.sdl.com/web/schemas/core:FAQs, found these mappings: [class com.sdl.dxa.modules.faqs.model.FAQs, class com.sdl.dxa.modules.faqs.model.FAQs] but there are no core schemas called FAQs

Caused by: com.sdl.webapp.common.exceptions.DxaException: Exception happened while creating a entity model from: EntityModelData(id=4560, componentTemplate=null, linkUrl=null, content=null, binaryContent=null, externalContent=null) 	at com.sdl.dxa.tridion.mapping.impl.DefaultModelBuilder.buildEntityModel(DefaultModelBuilder.java:133) 	at com.sdl.dxa.tridion.mapping.impl.ModelBuilderPipelineImpl.createEntityModel(ModelBuilderPipelineImpl.java:86) 	at com.sdl.dxa.tridion.mapping.impl.DefaultContentProvider._convertEntities(DefaultContentProvider.java:120) 	at com.sdl.dxa.tridion.mapping.impl.DefaultContentProvider.populateDynamicList(DefaultContentProvider.java:213) 	... 122 common frames omitted Caused by: com.sdl.webapp.common.exceptions.DxaException: Cannot get a view model tpe because of semantic mapping exception 	at

Caused by: com.sdl.webapp.common.api.mapping.semantic.SemanticMappingException: Ambiguous semantic mapping for http://www.sdl.com/web/schemas/core:FAQs, found these mappings: [class com.sdl.dxa.modules.faqs.model.FAQs, class com.sdl.dxa.modules.faqs.model.FAQs]
	at com.sdl.webapp.common.impl.mapping.SemanticMappingRegistryImpl.getEntityClassByFullyQualifiedName(SemanticMappingRegistryImpl.java:334)

To resolve the SemanticMappingException caused by Ambiguous semantic mapping, I then created a customTeaser which is mapped to my schema FAQs @SemanticEntity(entityName = "FAQs", vocabulary = SDL_CORE, prefix = "f")
. In my custom ContentListController.enrichModel function, when it calls contentProvider.populateDynamicList(dynamicList, webRequestContext.getLocalization());, I can see from the logs that it calls my custom DynamicList and the DefaultModelBuilder that is called after this prints the following logs.

Hi,
I'm looking into this issue and was wondering if you could give me a few more details regarding your actual code, schema & models. If possible could you supply the schemas/models you are using and the code you are using. Such as your DynamicList<,> implementation, browser query and usage of these. I'm trying to set up an environment to reproduce these issues so this would save a lot of time if you could supply this.

Many thanks
Paul.

Hi Paul, Sorry for the delay. I have attached a document with screenshots of the schema, models and controller we are using. Let me know if you need anything else.

Hi Sudha,
Maybe you forgot to attach them ? :)
