Examples and additional notes
Related issue: TASKSNET-10378 - Fix calculation of formula results when operand is #ERROR value
Read-only property ExtendedAttribute.IsErrorValue was added to provide an ability to check whether the value of calculated custom attribute cannot be calculated (due to error in input arguments or an error in the formula).
Project project = new Project();
ExtendedAttributeDefinition attributeDefinitions = ExtendedAttributeDefinition.createTaskDefinition(ExtendedAttributeTask.Cost1, "Cost ratio");
attributeDefinitions.setFormula("[Cost] / [Overtime Cost]");
project.getExtendedAttributes().add(attributeDefinitions);
Task task = project.getRootTask().getChildren().add("Task 1");
ExtendedAttribute calculatedAttribute = attributeDefinitions.createExtendedAttribute();
task.getExtendedAttributes().add(calculatedAttribute);
task.set(Tsk.OVERTIME_COST, BigDecimal.ZERO);
// Output is "#Error" because Overtime Cost is zero.
System.out.println("Calculated attribute value: " + (calculatedAttribute.isErrorValue() ? "#Error" : calculatedAttribute.getNumericValue()));
task.set(Tsk.COST, BigDecimal.valueOf(123));
task.set(Tsk.OVERTIME_COST, BigDecimal.valueOf(150));
System.out.println("Calculated attribute value: " + (calculatedAttribute.isErrorValue() ? "#Error" : calculatedAttribute.getNumericValue()));New methods for searching Views in ViewCollection
getByViewScreen and getByName methods were added to ViewCollection in order to allow searching of Views by Screen and by Name property respectively.
Project project = new Project("Project.mpp");
View taskUsageView = project.getViews().getByViewScreen(ViewScreen.TaskUsage);
View ganttChartView = project.getViews().getByName("&Gantt Chart");
