How to set datasource to ValueMapResourceWrapper.

[LiYanfei]

I want use ValueMapResourceWrapper to create a Select field. How to set options by DataSource.

public class TestModel extends WCMUsePojo {
    @Override
    public void activate() throws Exception {
      ValueMapResourceWrapper wrapper = new ValueMapResourceWrapper(getResource(), "granite/ui/components/coral/foundation/form/select");
      wrapperProperties = wrapper.adaptTo(ValueMap.class);
      wrapperProperties.put("name", "fieldName");
      wrapperProperties.put("fieldLabel", "Label");

      List<Resource> itemValues = new ArrayList<>();
      for (a loop) {
        ValueMap vm = new ValueMapDecorator(new HashMap<String, Object>());
        vm.put("text", "text1");
        vm.put("value", "value1");
      }
      DataSource ds = new SimpleDataSource(itemValues.iterator());
      // How to set datasource
      

      getSlingScriptHelper().include(wrapper);
    }
}

Dear,

Thanks for your idea.

If the select field has resource and [datasource] node, it can work. But the select is created by [ValueMapResourceWrapper]. It is no resource, actual node and [datasource] node. I have try to below source code, but not work too.

wrapperProperties.put("datasource", ds);

@LiYanfei 

Could you please elaborate the need/use case for programmatic creation of select resource 

[LiYanfei]

It use for page properties, and reference from CF Model.

eg: add a select field to CF Model,that be added on the page properties.

[Vijayalakshmi_S]

Dropdown field is available in CF model via the field named "Enumeration".

Did you try that already ?

[arunpatidar · Accepted solution]

can you try with below, I am not sure if this is gonna work or not

request.setAttribute(DataSource.class.getName(), ds);

[LiYanfei]
