When is interpolation done for components.xml?
Here is a fragment of my components.xml...
<drools:rule-agent name="isDealRuleBase"
url="http://#{serverInfoTest.webServerURL}/drools-jbrms/org.drools.brms.JBRMS/package/com.homeq.cam.deal.domain.isDeal/LATEST"
local-cache-dir="/var/data/cam"
poll="30"
auto-create="true">
</drools:rule-agent>
.
.
<drools:managed-working-memory
name="isDealWorkingMemory"
auto-create="true"
rule-base="#{isDealRuleBase}"/>
.
.
Here is a fragment of pageflow.jpdl.xml
<decision name="isDealQualified">
<handler class="com.homeq.drools.HomEqDroolsDecisionHandler">
<workingMemoryName>isDealWorkingMemory</workingMemoryName>
<assertObjects>
<element>#{loanInfo}</element>
</assertObjects>
</handler>
<transition to="isPreviousMod" name="yes"></transition>
<transition name="no" to="isFastTrackQualified"></transition>
</decision>
The application boots with no problems, but when the pageflow executes, it immediately goes into com.homeq.drools.HomEqDroolsDecisionHandler - never calls serverInfoTest.getWebServerURL(); The interpolation of #{serverInfoTest.webServerURL} never occurs and I get the following...

Why was the EL expression in components.xml (i.e., #{serverInfoTest.webServerURL} not interpolated? is interpolation handled by the declared class, in this case, RuleAgent, or is interpolation done before the class is passed its parameters?
