[SOLVED]Custom View and persons as attribute

As we transition to the new Hyland Community, some post links may be temporarily disrupted as we finalize redirects. We apologize for the inconvenience and are working to resolve this as quickly as possible. Details.

Hello,

I am working on a Custom View which will show custom properties from an aspect on a space. While the cm:text properties are printed well, the persons (cmerson) is a problem. I have two types, one which is a relation with only one person, and an other which has set the attribute <many/> to true.

Now, when printing I say the following:

${space.properties["my:projectmanager"].properties.userName}‍

This does give the following error:

13:34:28,380 ERROR [org.alfresco.web.ui.common.Utils] Error during processing of the template 'get(properties) failed on instance of org.alfresco.repo.template.TemplateNode'. Please contact your system administrator.

(1)Also note that there exists someone, as in Properties window I can view and change this attribute. What the traceback says is "Node does not exist: workspace://SpacesStore/d0fda50a-3d78-4472-8fb7-5459cd7c82ed".
The webclient gives the following (JSF?) warning (below):

Error during processing of the template 'get(properties) failed on instance of org.alfresco.repo.template.TemplateNode'. Please contact your system administrator.‍

(2)My second cmerson (my:teacher) property doesn't throw any exceptions, but gives admin. When no teacher is selected, it also gives the same result (admin).

The two properties are defined in the model configuration file. The model (aspect) should not be causing the problem. Otherwise it should give the following error:

Caused by: freemarker.core.InvalidReferenceException: Expression space.properties["my:teacher"]  is undefined on …‍

(3)The last property, my:students, is a relation with "many" option set to one, collection of cmerson entities. Here I use the following code to loop the list:

<#foreach item in space.properties["my:students"]>
${item["properties"]["userName"]}<br>
</#foreach>‍‍‍

I get the following error which says the property doesn't exists, I double checked and it does exist…:

Caused by: freemarker.core.InvalidReferenceException: Expression space.properties["my:students"] is undefined on line 16, column 19 in workspace://SpacesStore/801f1a06-2980-4fa8-acd7-eef1ca324b8a. …‍

Thanks very much.

I see that I am using associations and for this, associaton methods are obligated.
I use the following:

${space.assocs["my:projectmanager"].properties.userName}‍

Which gives the following exceptions:
