Bug 167267 getParameterDisplayText does not work on MasterPage in PDF
getParameterDisplayText does not seem to work when used on MasterPage. This problem seems to be limited to ReportViewer and PDF format. Table from my testing Deployed to Tomcat View Report in Web Viewer View Report as PDF Format HTML OK OK N/A PDF FAIL FAIL OK Incidentally getParameterDisplayText works fine in all of the above cases if used in footer of table in the report body.

* Since the data set in master page will be executed in each page
	 * and while the data set in report body will only be executed once,
	 * we need to remember the current report item is in master page or not.
	 * This will be used to help store the executed resultSetID and load it
	 * to distinguish them.
