Re: [rules-users] Cannot invoke method because of ArrayIndexOutOfBoundsException

Like you wish wolfgang. The complete Rule is: rule "Generate Finding_ConceptId" no-loop when $a1:ODMAnswer( q1:QuestionId, q1.toLowerCase.contains("diagnose") || q1.toLowerCase.contains("indication"), q1.toLowerCase.contains("sections"), a1_begin:begin, label1:ResponseAttribute) $a2:ODMAnswer( ResponseAttribute.contains(label1), QuestionId.contains("sectionheader"), comesBefore($a1,$a2)); $a3:ODMAnswer( q3:QuestionId, !q3.contains("finding.conceptId"), !q3.contains("itemGroup"), !q3.contains("section"), a3_begin:begin, a3_end:end, label2:ResponseAttribute, isInAnnotation($a1,$a3)) $a4:ODMAnswer( q4:QuestionId.contains("finding.conceptId"), a4_begin:begin, comesAfter($a2,$a4), isBetween($a2,$a3,$a4), isInAnnotation($a1,$a4)) not $a5:ODMAnswer( isInAnnotation($a1,$a5), isBigger($a3,$a5), !isEqual($a3,$a4,$a5)) then String questionId = "finding.conceptId"; String attribute = label1 +" "+ label2; int begin = a4_begin; int ende = a3_end; boolean addToIndexes = true; insert(annotate(aJCas, questionId, attribute, begin, ende, addToIndexes)); end The functions are in a seperate FactChecker class, because the "incode-comparison" was too much of a chaos. So I wrote functions which explains themselves what they do: ================================================================== public static boolean isInAnnotation(Annotation a, Annotation b){ if(isNull(a,b)){ return false; } if(b.getBegin() > a.getBegin() && b.getEnd() < a.getEnd()){ return true; } if(a.getBegin() > b.getBegin() && a.getEnd() < b.getEnd()){ return true; } return false; } ================================================================== public static boolean isInAnnotation(Annotation... a){ for (int i = 0; i < a.length; i++){ if(i+1 == a.length){ return false; } if(isInAnnotation(a[i], a[i+1])){ return true; } } return false; } ================================================================== public static boolean comesBefore(Annotation a, Annotation b){ if(isNull(a,b)){ return false; } if(b.getEnd() <= a.getBegin()){ return true; } return false; } ================================================================== public static boolean comesAfter(Annotation a, Annotation b){ if(isNull(a,b)){ return false; } if(a.getEnd() <= b.getBegin()){ return true; } return false; } ================================================================== public static boolean isEqual(Annotation a, Annotation b){ if(isNull(a,b)){ return false; } if(a.equals(b)){ return true; } return false; } ================================================================== public static boolean isEqual(Annotation... a){ ArrayList<Annotation> outLoop = new ArrayList<Annotation>(Arrays.asList(a)); ArrayList<Annotation> inLoop = new ArrayList<Annotation>(Arrays.asList(a)); for (Annotation anno1 : outLoop) { if(anno1 == null){ } inLoop.remove(anno1); for (Annotation anno2 : inLoop) { if(isEqual(anno1,anno2)){ return true; } } } return false; } ================================================================== public static boolean isNull(Annotation... a){ for (Annotation annotation : a) { if(annotation == null){ return true; } } return false; } ================================================================== public static boolean isBigger(Annotation a, Annotation b){ if(isNull(a,b)){ return false; } if(a.getBegin() == b.getBegin() && a.getEnd() < b.getEnd()){ return true; } if(b.getBegin() < a.getBegin() && a.getEnd() == b.getEnd()){ return true; } if(b.getBegin() < a.getBegin() && a.getEnd() < b.getEnd()){ return true; } return false; } ================================================================== public static boolean isBetween(Annotation a, Annotation b, Annotation c){ if(isNull(a,b,c)){ return false; } Annotation min = getMin(a,b); Annotation max = getMax(a,b); if(isOverlapping(a,c) || isOverlapping(b,c)){ return true; } if(c.getBegin() > min.getEnd() && c.getEnd() < max.getBegin()){ return true; } return false; } ================================================================== public static Annotation getMax(Annotation a, Annotation b){ isNull(a,b); if(a.getBegin() >= b.getBegin()){ return a; } return b; } ================================================================== public static Annotation getMin(Annotation a, Annotation b){ isNull(a,b); if(a.getEnd() <= b.getEnd()){ return a; } return b; } ================================================================== I've posted all functions that are used by the rule. Actually it crushes if I use more than 2 statements in the isEqual() call in $a5. It works with !isEqual($a3,$a4) && !isEqual($a3,$a5) && !isEqual($a4,$a5) but not with !isEqual($a3,$a4,$a5). So do you got an idea where the problem comes from?
