Does an OnReadOnly event exist or something like that?

Is it possible to create an action that is triggered every time a control is changed to read only?

I want this action to be triggered by all control on my form.

I want to take the triggered control and save it to a variable then I will set the value to null.

How do I check that a control is read only when a control is changed?

Kevin,

Yes, there are xforms-readonly/xforms-readwrite events on each control
bound to a node.

Re: Does an OnReadOnly event exist or something like that?

I am using Orbeon forms 3.8. Is it possible to have an action that is used by all controls when the xforms-readonly event is triggered. I have 100+ controls that change the xforms-readonly event.

So my perfect solution would be a single action that gets called by each control when an option changes the readonly status of a control, then that control has its value set to null to clear that field.

<xforms:action ev:event="xforms-readonly">
<xxforms:variable name="ChangedControl-name" select="'ChangedControl'" as="xstring"/>
<xforms:setvalue ref="instance('fr-form-instance')/*/*[name() = $ChangedControl-name]" value="null"/>
</xforms:action>

Is this the right way or what would be the better way to do what I want?
How would I know what control triggered the readonly event?

Kevin,

I think event('xxforms:binding') will do exactly what you are looking for: it returns the single-node targeted by the event, in this case the xforms-readonly. So can just write:

<xforms:setvalue ev:event="xforms-readonly" ref="event('xxforms:binding')"/>

This is simpler and more robust, as this code won't depend on what the instance you're using looks like. You can find a short example that shows this in action at: https://gist.github.com/1921830

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

Alex
