Dynamic Multiselect Dropdown

[Leandro Belluscio]

Hi Guys, 

I'm working with dynamic dropdown plugin, I created a CustomValueListProvider and cofigured it in cms/console it is works fine. But now I need a multiselection using a CustomValueListProvider, unfortunatly the DynamicDropdownMultiselect only supports items from a value list document, in fact there is no option in the document editor to add a dynamic dropdown multiselec. If I add a DynamicDropdown and check the "multiple" option I get this error

An error has occurred, sorry for that.

java.lang.IllegalStateException: org.onehippo.forge.selection.frontend.plugin.DynamicDropdownPlugin does not support fields that are multiple: please use org.onehippo.forge.selection.frontend.plugin.DynamicMultiSelectPlugin for that. Field name is *.
Failed to instantiate plugin class 'org.onehippo.forge.selection.frontend.plugin.DynamicDropdownPlugin' for wicket id 'home.cluster.cms-static.plugin.servicesLoader.cluster.cms-services.plugin.defaultEditorFactory.cluster.cms-editor.plugin.editorPlugin.cluster._default_.plugin.preview.cluster._default_.plugin.supplier-preview.cluster..plugin.home.cluster.cms-static.plugin.servicesLoader.cluster.cms-services.plugin.defaultEditorFactory.cluster.cms-editor.plugin.editorPlugin.cluster._default_.plugin.preview.cluster._default_.plugin.supplier.cluster._default_.service.wicket.id' in plugin 'home.cluster.cms-static.plugin.servicesLoader.cluster.cms-services.plugin.defaultEditorFactory.cluster.cms-editor.plugin.editorPlugin.cluster._default_.plugin.preview.cluster._default_.plugin.supplier-preview.cluster..plugin.home.cluster.cms-static.plugin.servicesLoader.cluster.cms-services.plugin.defaultEditorFactory.cluster.cms-editor.plugin.editorPlugin.cluster._default_.plugin.preview.cluster._default_.plugin.supplier.cluster._default_.plugin.root' (JcrPluginConfig:/hippo:namespaces/system/DynamicDropdown/editor:templates/_default_/root)

So there is a DynamicMultiSelec plugin, but it is not available in the document editor, I copy the DynamicaDropdown JCR node

Now the Plugin is available in the document editor

But it doesn't work, when hippo try to instantite it there is a class cast exception in FieldPluginHelper clas in method:

 public JcrNodeModel getNodeModel() {

        return (JcrNodeModel) getPluginContext().getService(getPluginConfig().getString("wicket.model"),

                IModelReference.class).getModel();

    }

the  getPluginContext().getService(getPluginConfig().getString("wicket.model"), IModelReference.class).getModel() returns a org.hippoecm.frontend.model.properties.JcrPropertyValueModel object and it is trying cast to JcrNodeModel

Is possible have a Mutltiselect dropdown available in document editor?

Thanks!
