sap.viz.ui5.Column in a sap.m.Page error

Hi Experts,

I'm trying to use class sap.viz.ui5.Column to create chart, and when using it alone, everything works as expected:

<mvc:View

  controllerName="Graphic"

  xmlns="sap.m"

  xmlns:viz="sap.viz.ui5"

  xmlns:mvc="sap.ui.core.mvc">

        <viz:Column id="idViz"></viz:Column>

</mvc:View>

But, If I try to add this chart inside of a sap.m.Page element, like below:

<mvc:View

  controllerName="Graphic"

  xmlns="sap.m"

  xmlns:viz="sap.viz.ui5"

  xmlns:mvc="sap.ui.core.mvc">

        <Page id='idApp' showNavButton="true" navButtonPress="handleNavButtonPress">      

             <viz:Column id="idViz"></viz:Column>

        </Page>

</mvc:View>

When running including the Page component, nothing is showed and no error is showed in the console.

Any idea what might be wrong here?

PS: The code in the onInit method of the controller is not changed, just the view.xml file is changed. Without the Page component works, and with it doesn't.

Thanks and regards,
