Show message and Load action only when showing section

[Javier Echaniz]

Hi, I'm trying to show a message and execute an action only when a section of the form is shown.

I've seen the event fr-section-shown, but i don't get with the key to be able to show the message only when a section fo the form is shown.

Thanks

Hi Javier,

Could you create an example on demo.orbeon.com with the code you've written so far?

I've forgotten to say that i'm using the 2018 version.

Hi Javier,

So you'd like to execute an action when a given section of the form is shown, leveraging the `fr-section-shown` event. You could do this in plain XForms, by adding the following, say right inside the `<xf:model>`, at towards the top of the source:

    <xf:action observer="fr-view-component" event="fr-section-shown">
        <xf:message value="'fr-section-shown'"/>
    </xf:action>

If you're using Orbeon Forms CE, I'd recommend you write plain XForms, instead of relying on the markup produced by Orbeon Forms PE for actions/services, which may or may not be supported by future versions of Orbeon Forms CE. This is also true for the action syntax: if I were you, I'd be more comfortable just writing XForms for that.

You'll let me know if this works for you,

Perfect, it works.

Lot of thanks

Excellent Javier, and thanks for the confirmation. And soon enough, you'll be mastering all the ins and outs of XForms!
