Bug 175637 NPE when input parameter to document in ReportRunner.[0600]
Description: NPE when input parameter to document in ReportRunner. Build number:2.2.0.v200702251739-M5-rebuild Steps to reproduce: 1. Unzip birt runtime package to get ReportEngine folder. 2. Copy attached report into the folder. 3. Run command as genReport -m run -p "sample=sample" -p "Cust=200" test1.rptdesign genReport -m render -p "sample=sample" -p "Cust=200" test1.rptdocument Expected result: In the second command, document need no parameters input, so just ignore the input parameter values. Actual result: NPE is thrown out. Error log: SEVERE: exception in parsing the paramters java.lang.NullPointerException at org.eclipse.birt.report.engine.api.ReportRunner.renderReport(ReportRu nner.java:304) at org.eclipse.birt.report.engine.api.ReportRunner.execute(ReportRunner. java:157) at org.eclipse.birt.report.engine.api.ReportRunner.main(ReportRunner.jav a:117)
