Rule fires unexpectedly - not CE fails -------------------------------------- Key: JBRULES-2873 URL: https://issues.jboss.org/browse/JBRULES-2873 Project: Drools Issue Type: Bug Security Level: Public(Everyone can see) Components: drools-core Affects Versions: 5.1.1.FINAL Reporter: Wolfgang Laun Assignee: Mark Proctor Priority: Critical Fix For: 5.2.0.CR1 Attachments: sudokubug.tgz, sudokubug1.tgz, sudokubug2.tgz, sudokubug3.tgz The rule shown below fires, and then the code on the RHS prints "But cell ... matches" which is only possible when there is a Cell according to the constraints in the "not" CE. - The full Sudoku code is available. rule "column elimination" when not Setting() $i: Integer() # occurs in a Cell $c: Cell( free contains $i, $cs: cellSqr, $cc: cellCol ) # but not in another cell of the same square and a different column not Cell( this != $c, free contains $i, cellSqr == $cs, cellCol != $cc ) ## not ( $oc: Cell( this != $c ) ## and ## eval( $oc.getFree().contains( $i ) && ## $oc.getCellSqr().equals( $cs ) && ## ! $oc.getCellCol().equals( $cc ) ) ) # but there is a cell in the same column and another square containing this value $cx: Cell( freeCount > 1, free contains $i, cellCol == $cc, cellSqr != $cs ) then # remove the value from that other cell System.out.println( "column elimination due to " + $c.posAsString() + ": remove " + $i + " from " + $cx.posAsString() ); for( int iRow = 0; iRow < 9; iRow++ ){ for( int iCol = 0; iCol < 9; iCol++ ){ Cell cell = Sudoku.sudoku.cells[iRow][iCol]; if( ! cell.equals( $c ) && cell.getCellSqr().equals( $cs ) && ! cell.getCellCol().equals( $cc ) && cell.getFree().contains( $i ) ){ System.out.println( "But cell " + cell.toString() + " matches!" ); } } } for( Cell c: $cs.getCells() ){ System.out.print( c.posAsString() + ": " + c.getFree() + " cc="+c.getCellCol() + " cs="+c.getCellSqr() + "; " ); } System.out.println(); modify( $cx ){ blockValue( $i ) } end
