hi all, I am getting error in adhoc view editor when using topic with input control as datasource. I have drag and drop some field as column, using "Table" as layout, when I preview the data by "Sample Data" or "Full Data", the screen always prompt "An error occurred while performing the previous request". Below is part of the exception message captured from server log:ad hoc controller exception: An error occurred while performing the previous request.java.lang.NullPointerException at com.jaspersoft.commons.semantic.dsimpl.SQLGenerator$1.handleClauseChunk(SQLGenerator.java:556) at net.sf.jasperreports.engine.util.JRQueryParser.parseClause(JRQueryParser.java:208)[/code]If I remove the input control from topic, the adhoc view editor works and data can be displayed. Product Edition: Professional for AWSProduct Version: 6.3.0 Can anyone let me know how to fix this issue? Thank you in advance.
