Hi Jeff,

Have you tried a message action on DOMFocusIn?

<input ref="blah">
   <label>Name</label>
   <message ev:event="DOMFocusIn" level="ephemeral">Hello, 
world!</message>
</input>

You have to be careful to not use a modeless or modal message so the input 
doesn't lose focus as soon as it gains it and so that the input doesn't 
regain the focus as soon as the message is dismissed (which would cause 
the message to reappear).

Aside from that, you could also use group relevance (or even a switch) in 
combination with DOMFocusIn and DOMFocusOut event handlers, e.g.

<input ref="blah">
   <label>Name</label>
   <setvalue ev:event="DOMFocusIn" ref="@showme" value=" 'true' "/>
   <setvalue ev:event="DOMFocusOut" ref="@showme" value=" 'false' "/>
</nput>

<group id="helpForBlah" ref="blah[@showme = 'true']">
   ...
</group>

Note that a group is considered non-relevant if it binds to a non-relevant 
instance node OR if its expressed single node binding resolves to empty 
nodeset (OR it's within a non-relevant group or switch...).

RE: Newbie question: alternative to message/hint/help?







Hi all,

Just hoping for a short note indicating whether or not this is possible.
Knowing it's not possible would save me a lot of time.

If it is do-able, an indication of where to look in the specs would be 
much
appreciated.

All the best,

Jeff
