StackOverflowError on the treeview widget

We can configure a questionnaire and conduct the questionnaire but halfway trough the questionnaire we get this error: java.lang.StackOverflowError at org.hsqldb.store.BaseHashMap.containsKey(Unknown Source) at org.hsqldb.lib.OrderedIntHashSet.contains(Unknown Source) at org.hsqldb.Scanner.scanWhitespace(Unknown Source) at org.hsqldb.Scanner.scanSeparator(Unknown Source) at org.hsqldb.Scanner.scanNext(Unknown Source) at org.hsqldb.ParserBase.read(Unknown Source) at org.hsqldb.ParserDQL.readColumnOrFunctionExpression(Unknown Source) at org.hsqldb.ParserDQL.XreadSimpleValueExpressionPrimary(Unknown Source) at org.hsqldb.ParserDQL.XreadAllTypesValueExpressionPrimary(Unknown Source) at org.hsqldb.ParserDQL.XreadAllTypesPrimary(Unknown Source) at org.hsqldb.ParserDQL.XreadAllTypesFactor(Unknown Source) at org.hsqldb.ParserDQL.XreadAllTypesTerm(Unknown Source) at org.hsqldb.ParserDQL.XreadAllTypesCommonValueExpression(Unknown Source) at org.hsqldb.ParserDQL.XreadValueExpression(Unknown Source) at org.hsqldb.ParserDQL.XreadSelect(Unknown Source) at org.hsqldb.ParserDQL.XreadQuerySpecification(Unknown Source) at org.hsqldb.ParserDQL.XreadSimpleTable(Unknown Source) at org.hsqldb.ParserDQL.XreadQueryPrimary(Unknown Source) at org.hsqldb.ParserDQL.XreadQueryTerm(Unknown Source) at org.hsqldb.ParserDQL.XreadQueryExpressionBody(Unknown Source) at org.hsqldb.ParserDQL.XreadQueryExpression(Unknown Source) at org.hsqldb.ParserDQL.XreadSubqueryBody(Unknown Source) at org.hsqldb.ParserDQL.XreadInPredicateRightPart(Unknown Source) at org.hsqldb.ParserDQL.XreadPredicateRightPart(Unknown Source) at org.hsqldb.ParserDQL.XreadBooleanPrimaryOrNull(Unknown Source) at org.hsqldb.ParserDQL.XreadBooleanFactorOrNull(Unknown Source) at org.hsqldb.ParserDQL.XreadBooleanTermOrNull(Unknown Source) at org.hsqldb.ParserDQL.XreadBooleanValueExpression(Unknown Source) at org.hsqldb.ParserDQL.readWhereGroupHaving(Unknown Source) at org.hsqldb.ParserDQL.XreadTableExpression(Unknown Source) at org.hsqldb.ParserDQL.XreadQuerySpecification(Unknown Source) at org.hsqldb.ParserDQL.XreadSimpleTable(Unknown Source) at org.hsqldb.ParserDQL.XreadQueryPrimary(Unknown Source) at org.hsqldb.ParserDQL.XreadQueryTerm(Unknown Source) at org.hsqldb.ParserDQL.XreadQueryExpressionBody(Unknown Source) at org.hsqldb.ParserDQL.XreadQueryExpression(Unknown Source) at org.hsqldb.ParserDQL.compileCursorSpecification(Unknown Source) at org.hsqldb.ParserCommand.compilePart(Unknown Source) at org.hsqldb.ParserCommand.compileStatements(Unknown Source) at org.hsqldb.Session.executeDirectStatement(Unknown Source) at org.hsqldb.Session.execute(Unknown Source) at org.hsqldb.jdbc.JDBCStatement.fetchResult(Unknown Source) at org.hsqldb.jdbc.JDBCStatement.executeQuery(Unknown Source) at org.apache.commons.dbcp.DelegatingStatement.executeQuery(DelegatingStatement.java:208) at org.apache.commons.dbcp.DelegatingStatement.executeQuery(DelegatingStatement.java:208) at w.a(SourceFile:322) at w.a(SourceFile:215) at w.a(SourceFile:165) at w.a(SourceFile:154) at n.a(SourceFile:43) at dq.a(SourceFile:200) at dq.a(SourceFile:158) at dq.a(SourceFile:86) at du.a(SourceFile:67) at l.a(SourceFile:45) at a.a(SourceFile:243) at gW.b(SourceFile:124) at gW.a(SourceFile:65) at gS.a(SourceFile:60) at gS.executeAction(SourceFile:20) at com.mendix.systemwideinterfaces.core.UserAction.execute(SourceFile:48) at com.mendix.core.actionmanagement.CoreAction.call(SourceFile:434) at hg.b(SourceFile:155) at com.mendix.core.Core.retrieveXPathQuery(SourceFile:820) at lE.a(SourceFile:91) at mv.a(SourceFile:72) at mu.executeAction(SourceFile:102) at com.mendix.systemwideinterfaces.core.UserAction.execute(SourceFile:48) at com.mendix.core.actionmanagement.CoreAction.call(SourceFile:434) at hg.b(SourceFile:155) at com.mendix.core.Core.executeSync(SourceFile:176) at lk.a(SourceFile:71) at mv.a(SourceFile:72) at mu.executeAction(SourceFile:102) at (removed numerous repeats) com.mendix.systemwideinterfaces.core.UserAction.execute(SourceFile:48) at com.mendix.core.actionmanagement.CoreAction.call(SourceFile:434) at hg.b(SourceFile:155) at com.mendix.core.Core.executeSync(SourceFile:176) at lk.a(SourceFile:71) Can someone help...?

You probably jump from A to B to C and back to A or created other kind of loops in your questionnaire. E.g. Dependencies in conditions between questions with loops.
