Simple workaround for partial refresh issues with radio buttons

Update, 14.03.14: I had some issues with this technique when used inside a ExtLib dialog. I suspect this has something to do with the dialog having it's own form. To make it work inside the dialog, I added a parameter for the execId. If I remember correctly, execId specifies the part of the XPages tree that should be processed. It can be the same as the target of the refresh.

Example of use with execId:

XSP.partialRefreshPost( '#{id:targetOfRefresh}', { execId: '#{id:targetThatShouldBeProcessed}' } );

I had some issues getting partial refresh triggered by radio buttons to work as I wanted to across browsers. I found a simple workaround. Instead of specifying the partial refresh in the event handler, I set no submission for the server side part, and execute a slightly delayed XSP.partialRefreshPost from the client side event action:

<xp:radioGroup id="someId" value="#{document.someField}" defaultValue="yes">
 <xp:eventHandler event="onclick" submit="false">
   <xp:this.script><![CDATA[setTimeout( function(){
 XSP.partialRefreshPost( '#{id:targetOfRefresh}' );
}, 50 );]]></xp:this.script>
 </xp:eventHandler>
 <xp:selectItem itemValue="yes" itemLabel="Yes" />
 <xp:selectItem itemValue="no" itemLabel="No" />
</xp:radioGroup>

This seems to work nicely across the browsers I tested in, regardless of triggering the value change through the radio button or the label.

Strange implementation of Document.setPreferJavaDates( true )

I wanted to try the Document.setPreferJavaDates today and see how it worked.

I called Document.setPreferJavaDates( true ); to ensure that no (Notes)DateTime objects were created as I didn't need them/didn't want to deal with recycling.

First I tried:
Document.getItemValueDateTimeArray( "fieldname" );
This returned a Vector of DateTime.

Then I tried:
Document.getItemValue( "fieldname" );
This also returned a Vector of DateTime.

The way that finally worked as expected (returned a Vector of java.util.Date) was this:
Document.firstItem( "fieldname" ).getValues();

I would imagine this is the least used method among developers wanting to get a date value from a field. This code was executed on a server running Domino 8.5.3FP2
