<!--
This file demonstrates how the dojox.wire code can be used to do declarative
wiring of events. Specifically, it shows how you can chain actions together
in a sequence. In this case the setting of a value on one textbox triggers a
copy over to another textbox. That in turn triggers yet another copy to another
text box.

<!-------------------------------- Using dojox.wire, declaratively wire up the widgets. --------------------------->
<!--
This is an example of using the declarative data value definition.
These are effectively declarative variables to act as placeholders
for data values.
-->
<div dojoType="dojox.wire.ml.Data"
id="data">
<div dojoType="dojox.wire.ml.DataProperty"
name="tempData"
value="">
</div>
</div>
<!--
Whenever a key is entered into the textbox, copy the value somewhere, then invoke a method on another widget, in this case
on just another text box.
-->
<div dojoType="dojox.wire.ml.Action"
id="action1"
trigger="inputField"
triggerEvent="onkeyup">
<div dojoType="dojox.wire.ml.Invocation" object="inputField" method="getValue" result="data.tempData"></div>
<div dojoType="dojox.wire.ml.Invocation" id="targetCopy" object="targetField1" method="setValue" parameters="data.tempData"></div>
</div>
<!--
Whenever the primary cloning invocation completes, invoke a secondary cloning action.
-->
<div dojoType="dojox.wire.ml.Action"
id="action2"
trigger="targetCopy"
triggerEvent="onComplete">
<!--
Note that this uses the basic 'property' form of copying the property over and setting it. The Wire
code supports both getX and setX functions of setting a property as well as direct access. It first looks
for the getX/setX functions and if present, uses them. If missing, it will just do direct access. Because
of the standard getValue/setValue API of dijit form widgets, these transfers work really well and are very compact.

<div dojoType="dojox.wire.ml.Transfer" source="targetField1.value" target="targetField2.value"></div>
