issue with changed facet api in the famportal case - ui does not display details anymore

[Malte]

Hi jri, i was wondering what did change as i updated the dm4-kiezatlas-famportal but from 4.4.3 to 4.7 and now the display of detailed information about a geo object in the "grafische redaktionswerkzeug" does not work because of the following error thrown at server side.

I must have overlooked something and something must have changed in the dm4-facets plugin as it worked fine before:

Do you have an idea what exactly has changed that this new error is thrown?

Thankful for your support.

[Malte]

For me it is somehow crucial that i can find a solution for this issue during the upcoming week. If this is a real issue and to be confirmed I would be very thankful for your support.

[jri]

Confirmed!

This problem was introduced in DM 4.6 in conjunction with custom association types.
Since DM 4.6 a ChildTopicsModel holds RelatedTopicModels (instead of TopicModels).

I'll fix that very soon.

In 7a894e17cb9594301625bdc4624555bdca605774/deepamehta:

Core: fix ChildTopicsModel? for multi-value (#985).

The ChildTopicsModel's put() method that takes a List parameter (for multi-value childs) doesn't throw this exception anymore:

java.lang.IllegalArgumentException: Tried to build a SimpleValue from a java.util.ArrayList (expected are String, Integer, Long, Double, or Boolean)

As a consequence the Facets API's getFacettedTopic() method works properly.

Thanks to Malte for reporting!

BREAKING CHANGE

Core API:

1 method changed in DeepaMehtaUtils:

public static List<TopicModel> toTopicModels(Iterable<? extends Topic> topics)
-->
public static      <M> List<M> toModelList(Iterable<? extends DeepaMehtaObject> objects)

It can now map any DM object collection to the corresponding model objects.
Note the method renaming.

See #985.

Thanks for the progress here! Cool. I will definitely make use of it and test it during the next week.
Thank you too! :)

[Malte]

I can confirm that the changes fixed this "details not shown"-issue in the "grafisches redaktionswerkzeug". From my point of view we could close this issue as fixed. Thanks for your support.
