Re: [Xsltforms-support] Can you use dispatch to invoke a trigger?

[Mark L. <tin...@gm...>]

William,
Thanks for that. I wanted to keep the events in the right place in the form and call it, so I didn’t consider a custom event originally.

Happily, I got it to work eventually like so:

<xf:trigger>	
	        <xf:label>Test-Trigger</xf:label>
		 <xf:dispatch targetid="remote" name="DOMActivate" ev:event="DOMActivate" ></xf:dispatch>
</xf:trigger>

<xf:trigger id="remote">
	        <xf:label>Child-Trigger</xf:label>
	        <xf:action ev:event="DOMActivate">
				<xf:message>It works!</xf:message>
		</xf:action>
</xf:trigger>

Rgds,

It’s a pretty long list so I want to duplicate the buttons at the top as well but I don’t really want to duplicate the event code in these, I just want to get them to activate their respective originals.
