RE: Form controls reacting to several events

Hi Xavier,

let's see if I understand you correctly: You propose to add
"maxOccurs='unbounded'" to the following line:


  <xsd:group name="commonUIChildren">
    <xsd:all>
	...
      <xsd:element ref="xform:action" minOccurs="0"/> <!-- here -->
	...
    </xsd:all>
  </xsd:group>
  
I'm afraid that would be another of the (in)famous "ordered and
unbounded vs. unordered and maxOccurs='1'" instances.

Other than that, what you suggest appears reasonable to me. We'll
discuss it at the next telephone conference.

Josef

Hi,

If I understand correctly the spec (more precisely §8 XForms Actions),
it's possible to launch several
actions on only one event for a formControl, but it's impossible to
launch several actions for different events.

For instance,it is legal (according to xforms schema) to have two
actions launched by an event:

<xform:input ref="boss:name">
      <xform:caption>Name</xform:caption>
      <xform:action event="mouseover">
           <xform:setValue ref="boss:surname" value="new value"/>
           <xform:setFocus idref="boss:surname"/>
      </xform:action>
</xform:input>

But the following isn't legal (actions are launched by two different
events), althought it seems useful:

<xform:input  ref="boss:name">
      <xform:caption>Name</xform:caption>
      <xform:action event="mouseover">
           <xform:setValue ref="boss:surname" value="new value"/>
      </xform:action>
      <xform:action event="Click">
           <xform:setFocus idref="boss:surname"/>
      </xform:action>
</xform:input>

So I think that we should put maxOcurrs = "unbounded" for xform:action
element 
in commonUIChildren group to define several actions launched by
different events.


Thank you for feedback.

Xavier
