Bursting XML Control File - only one variable substitution works

Question

Hello, I have the following from my bursting xml. In my subject I would like to have more than one substitution as in my example. Problem is that when I have more than one, the second one alway is "null". On there own they work fine. Is this a bug/limitation?
<xapi:message id="111" to="${ADMIN_EMAIL}" attachment="true" subject="Unigas Inv
oice No: ${TRX_NUMBER} for ${PARTY_NAME}">

Use this syntax in your burst file (note you will need the above patch applied).
<xapi:document output="${VAR - or hard code name here}" output-type="pdf" delivery="xxx" >
Alternate way (if you don't have the patch) is to use the bursting listener by implementing it and doing the following in the afterProcessDocument interface.
public void afterProcessDocument(int requestIndex, int documentIndex, Vector documentOutputs) {
String outFileName = (String)documentOutputs.get(0);
File newFile;
File oldFile = new File(outFileName);
newFile = new File(oldFile.getParent() + File.separator + "file" + oldFile.getName());
oldFile.renameTo(newFile);
documentOutputs.remove(0);
documentOutputs.add(0, newFile.getPath());
}
