I have a "Export to Excel" button on one of my pages. However when I press the button for anything more than 100 records I am getting a "null" error. Below is the stack trace from the modeler, any ideas? null at jY.a(SourceFile:119) at jY.a(SourceFile:75) at jY.a(SourceFile:54) at eb.a(SourceFile:224) at eb.b(SourceFile:184) at eb.a(SourceFile:110) at eb.execute(SourceFile:84) at jg.a(SourceFile:280) at jg.a(SourceFile:212) at jg.processRequest(SourceFile:168) at fq.a(SourceFile:75) at com.mendix.core.MxRuntime.processRequest(SourceFile:889) at com.mendix.m2ee.server.handler.RuntimeHandler.handle(RuntimeHandler.java:39) at org.eclipse.jetty.server.handler.HandlerWrapper.handle(HandlerWrapper.java:113) at org.eclipse.jetty.server.Server.handle(Server.java:334) at org.eclipse.jetty.server.HttpConnection.handleRequest(HttpConnection.java:559) at org.eclipse.jetty.server.HttpConnection$RequestHandler.content(HttpConnection.java:1007) at org.eclipse.jetty.http.HttpParser.parseNext(HttpParser.java:747) at org.eclipse.jetty.http.HttpParser.parseAvailable(HttpParser.java:209) at org.eclipse.jetty.server.HttpConnection.handle(HttpConnection.java:406) at org.eclipse.jetty.io.nio.SelectChannelEndPoint.run(SelectChannelEndPoint.java:462) at org.eclipse.jetty.util.thread.QueuedThreadPool$2.run(QueuedThreadPool.java:436) at java.lang.Thread.run(Thread.java:619)
