Adding a dynamic region/dataset after page loads

Question

I am trying to dynamicaly add a new spry driven select box
after the page has loaded to allow n select boxes to be displayed.
My initial spry select is as below and works fine.
<div id="orgDiv">
<div id="orgDiv0" spry:region="dsOrg[0]">
<select id="selOrg0"
onchange='_addOrg(this.options[this.selectedIndex].value);'>
<option>--- Select --- </option>
<option spry:repeat="dsOrg[0]"
value="{CHILD_ID}">{STR_TEXT} </option>
</select>
</div>
</div>
The onchange for the select triggers a JS function to add a
new spry region div and select box to the page. All fine so far,
the only problem is I need to initialise the new spry region as it
has been inserted after the initial Spry.Data.initRegions();
Theinitial spry region renders correctly but the javascript
added node (second one) hasn't been initialised by spry:
<div id="orgDiv0" class="">
<select id="selOrg0"
onchange="_addOrg(this.options[this.selectedIndex].value);">
<option>--- Select --- </option>
<option value="2">Group PLC </option>
<option value="3">GSD </option>
<option value="4">Country </option>
</select>
</div>
<div id="orgDiv1" spry:region="dsOrg[1]">
<select id="selOrg1"
onchange="_addOrg(this.options[this.selectedIndex].value);">
<option>--- Select --- </option>
<option value="{CHILD_ID}"
spry:repeat="dsOrg[1]">{STR_TEXT} </option>
</select>
</div>
If I call Spry.Data.initRegions(); it just zaps the contents
of my dynamically added div:
<div id="orgDiv1" class=""/>
Not so good...
Is there a way to use the API to initialiase a new spry
region using a new dataset after the page has loaded?

Are you getting the error in jdeveloper or in the envrionment? If you are getting the error in the environment verify whether the region is present in the MDS repository. You can use the exec jdr_utils.printdocument('/oracle/apps/ar/cusstd/localizationExt/webui/SiteTabsRN') for verifying. try adding the region to the project if you get the issue in Jdeveloper.
