XPages - Radio Group onChange featurette

HCL Domino Domino Forum

It is my experience that the onChange event of the RadioGroup (and CheckboxGroup) fire when the page loads. Surely this can’t be correct? Or am I missunderstanding the point of the onChange event?

Example code - check the server log and you’ll see that the onChange event fires 3 times each for radio and checkbox controls:-

xp:this.data

<xp:dominoDocument var="document1"

formName="ApplicationProfile">

</xp:dominoDocument>

</xp:this.data>

<xp:radioGroup id="radioGroup1" layout="pageDirection"

	value="#{document1.MIPStatus}">

	<xp:this.onchange><![CDATA[#{javascript:print( "radioGroup1 onChange has fired" );}]]></xp:this.onchange>

	<xp:selectItem itemLabel="option1"

	itemValue="Bulk" id="selectItem1">

	</xp:selectItem>

	<xp:selectItem itemLabel="option2"

		itemValue="Retail" id="selectItem2">

	</xp:selectItem>

	<xp:selectItem

		itemLabel="option3" itemValue="Both"

		id="selectItem3">

	</xp:selectItem>

</xp:radioGroup>

<xp:br></xp:br>

<xp:checkBoxGroup id="checkBoxGroup1"

	value="#{document1.MIPStatus}">

	<xp:this.onchange><![CDATA[#{javascript:print( "checkBoxGroup1 onChange has fired" );}]]></xp:this.onchange>

	<xp:selectItem itemLabel="option1"

		itemValue="Bulk" id="selectItem4">

	</xp:selectItem>

	<xp:selectItem itemLabel="option2"

		itemValue="Retail" id="selectItem5">

	</xp:selectItem>

	<xp:selectItem

		itemLabel="option3" itemValue="Both"

		id="selectItem6">

	</xp:selectItem></xp:checkBoxGroup>

Subject: No!!! not solution for Radio & Checkbox Groups

Now the onchange event doesn’t fire at all for Radio or Checkbox Groups.

Help!

Subject: Wondered if it isDataBeingLoaded would help

context.isDataBeingLoaded() is false when these onChange events fire. How the blazes am I supposed to spot if any field is changed without keeping a record of every field value? Painful.

Subject: Aha! Designer bug perhaps? One for Lotus to look at!

I entered the SSJS code into the “events - onchange” of the control’s All Properties. Interestingly, that code does NOT show up in the “Select & Change - onchange” on the “Events” Eclipse View!

If I remove it and then enter the same code into the “Select & Change” Script Editor on the Events Eclipse View, then it does appear in the All Properties. And executes when I would expect. Phew!

resultant Source XML from entering code into “Select & Change” :-

<xp:eventHandler event=“onchange” submit=“true”

refreshMode="complete">

xp:this.action</xp:this.action>

</xp:eventHandler>
