Strange Zimlet behavior

[JoshuaPrismon]

I've been hitting some really strange zimlet behavior with 5.0b1.

<zimlet name="org_technicaldetails_weather"  version="1.8" description="Weather Test Sample">
	   <zimletPanelItem label="Weather">
	      <toolTipText>Pull up the weather forecast for your location</toolTipText>
	      <contextMenu>
	         <menuItem label="Lookup the weather for your location" id="WEATHER">
	            <canvas type="dialog" title="Weather" width="800"  height="600" />
	            <actionUrl 
	            	target="http://www.wunderground.com/cgi-bin/findweather/getForecast">
	            	<param name="query">${prop.zipcode}</param>
	            </actionUrl>
	         </menuItem>
	      </contextMenu>
	   </zimletPanelItem>
   <userProperties>
	  <property type="string" name="zipcode" minLength="6" maxLength="10" label="Zip Code"/>
   </userProperties>

	</zimlet>

The problematic code is:

	            <actionUrl 
	           target="http://www.wunderground.com/cgi-bin/findweather/getForecast">
	            	<param name="query">${prop.zipcode}</param>
	            </actionUrl>

For whatever reason {prop.zipcode}, even when it exists, returns null. (I get my URI plus ?query=).

Also, the standard zimlet handler automatically pops up the property editor when I double click, but the okay button does not work. Thankfully the cancel button does, but it also saves the properrties(!!?)

<zimlet name="org_technicaldetails_weather"  version="1.8" description="Weather Test Sample">
	   <zimletPanelItem label="Weather">
	      <toolTipText>Pull up the weather forecast for your location</toolTipText>
	      <contextMenu>
	         <menuItem label="Lookup the weather for your location" id="WEATHER">
	            <canvas type="dialog" title="Weather" width="800"  height="600" />
	            <actionUrl 
	            	target="http://www.wunderground.com/cgi-bin/findweather/getForecast/${prop.zipcode}">
	            </actionUrl>
	         </menuItem>
	      </contextMenu>
	   </zimletPanelItem>
   <userProperties>
	  <property type="string" name="zipcode" minLength="6" maxLength="10" label="Zip Code"/>
   </userProperties>

	</zimlet>

For some reason

target="http://www.wunderground.com/cgi-bin/findweather/getForecast/${prop.zipcode}">
	            </actionUrl>

${prop.zipcode} is never substituted at all. This is a bad thing is a REST view of the world.

Any ideas?

I think these are just bugs. One thing you could try is to use Firebug or Venkman to step through the Zimlet code just before your URLs are called and make sure that prop is even defined. I know in some cases we use obj. rather than prop.
