DashBoard widget browser is not loading data from db

Support
#1

Hello,
I am trying to create a dashboard for my proyect, with the dashboard add-on, and everything was working ok until I decide to include a list from an entity. The thing is the windget is loading, but data doesn’t appears. I already chekc the query and this one is fine. I think I am using last version of the addon, but I am sure I have previous version of CUBA.

This is my XML:

    <?xml version="1.0" encoding="UTF-8" standalone="no"?>
<fragment xmlns="http://schemas.haulmont.com/cuba/screen/fragment.xsd">
    <data readOnly="true">
        <collection id="oTAvisosDc"
                    class="com.haulmont.app.entity.OTAviso"
                    view="oTAviso-view-all">
            <loader id="oTAvisosDl">
                <query>
                    <![CDATA[select e from pg_OTAviso e]]>
                </query>
            </loader>
        </collection>
    </data>
    <layout expand="oTAvisosTable"
            spacing="true">
        <table id="oTAvisosTable"
                    width="100%"
                    dataContainer="oTAvisosDc">
            <columns>
                <column id="dtype" caption="Tipo"/>
                <column id="estado" caption="Estado"/>
            </columns>
        </table>
    </layout>
</fragment>

There is any limitation with screen-fragments that avoid correct work with this?, because I am not getting errors. I am also checking in the controler with:

public void onInit(InitEvent event) {
    System.out.println("Is loaded");
}

But I am not getting response neither. I also try with dl.load(), and nothing.

I open to other ways of getting this list updated.
