Placeholder Help

[tspiva]

I'm using SAS 1.1 and I can not seem to get property placeholders to work and it must be something simple I'm not doing because it's to obvious for it not to work. I have a very simple application that loads an application context and then traces out the properties in it and it doesn't work. I even tried creating another class and autowireing values to it and it doesn't seem to replace the placeholders.

Here is my application file:

<?xml version="1.0" encoding="utf-8"?>
<s:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009"
                       xmlns:s="library://ns.adobe.com/flex/spark"
                       xmlns:mx="library://ns.adobe.com/flex/mx"
                       creationComplete="handleCreationComplete()">
	<fx:Script>
		<![CDATA[
			import org.springextensions.actionscript.context.support.FlexXMLApplicationContext;
			import org.test.MyClass;
			
			private var _applicationContext:FlexXMLApplicationContext;
			
			protected function handleCreationComplete():void
			{
				trace("Loading xml");
				_applicationContext = new FlexXMLApplicationContext("application-context.xml");
				_applicationContext.addEventListener(Event.COMPLETE, complete_handler);
				_applicationContext.load();
			}
			
			protected function complete_handler(event:Event):void {
				trace("Loaded xml");
				_applicationContext.removeEventListener(Event.COMPLETE, complete_handler);
				baseURL.text = _applicationContext.properties.getProperty("baseURL");
				trace("Base URL" + _applicationContext.properties.getProperty("baseURL"));
				trace("S1: " + _applicationContext.properties.getProperty("s1"));
				trace("S2: " + _applicationContext.properties.getProperty("s2"));
				
				var myObject:MyClass = _applicationContext.getObject("myObject");
				
				var resolver:PropertyPlaceholderResolver = new PropertyPlaceholderResolver();
				resolver.properties = _applicationContext.properties;
				resolver.resolvePropertyPlaceholders("s1");
				

				trace("S2: " + _applicationContext.properties.getProperty("s2"));
			}
		]]>
	</fx:Script>
	<s:Label x="10" y="10" text="Base URL:"/>
	<s:Label id="baseURL" x="77" y="10" text=""/>
	
	
</s:WindowedApplication>

My application-context.xml file is

<?xml version="1.0" encoding="UTF-8"?>
<objects xmlns="http://www.springactionscript.org/schema/objects"
                 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                 xsi:schemaLocation="http://www.springactionscript.org/schema/objects
                                        http://www.springactionscript.org/schema/objects/spring-actionscript-objects-1.0.xsd">

    <property name="baseURL" value="http://www.example.com" />
    
    <property name="s1" value="First string and ${s2}"/>
    <property name="s2" value="Second string"/>

    <object id="myObject" class="org.test.MyClass">
      <property name="string1" value="${s1}"/>
      <property name="string2" value="${s2}"/>
      <property name="string3" value="string 3 value"/>
    </object>
</objects>

Any my autowired class is:

package org.test
{
	public class MyClass
	{
		[Autowired]
		public var string1:String;
		
		[Autowired]
		public var string2:String;
		
		[Autowired]
		public var string3:String;
		
		[Autowired(externalProperty='s1')]
		public var string4:String;
	}
}

Nothing I have tried has been able to get "s1" to resolve to what I was expecting according to the documentation section 2.1.1.4. External property files
I've been pulling my hair out with this so any help would be appreciated!

hm, this might be a bug actually.

Have you tried putting the properties in an external file and checking if they are correctly loaded in that case?

Roland, thanks for your help!

Putting the properties in an external config file semi-worked. First, it failed because it couldn't find FlexPropertyPlaceholderConfigurer which wasn't a big deal as I get around that as with everything else in SAS. Now, any properties that defined in an external file will resolve correctly to stuff that is auto-wired and other objects using the placeholders for values.

However, any properties defined in the XML using <property name="s1" value="s1 value"/> throws a "Error: Could not resolve placeholder '${s1}'" when used somewhere.

So, I'll just move all properties to an external file to get around it.
