We are pleased to announce the release of Aspose.Tasks for Java 17.1.0. This month’s release improves the Extended Attributes implementation of a task. The modification makes it easy to add lookup extended attributes to a task. It also fixes a number of resources reported by our valued customers with the last month’s version of the API. For a detailed note on what is new and fixed, please visit the release notes section of Aspose.Tasks for Java documentation.

Improved Public API for Working with Custom Fields

This month’s release improves the implementation of adding Extended attributes to a task and resource. The new implementation makes it easy to create plain as well as Lookup custom fields to a project’s tasks and resources. The following static methods of ExtendedAttributeDefinition class are provided under this new implementation.

  • CreateTaskDefinition
  • CreateResourceDefinition
  • CreateLookupTaskDefinition
  • CreationLookupResourceDefinition

The following code sample illustrates the usage of these new methods exposed by the API.

// Create new project
Project project = new Project(dataDir + "project.mpp");

//Create an Extended Attribute Definition of Text1 type
ExtendedAttributeDefinition taskExtendedAttributeText1Definition = ExtendedAttributeDefinition.createTaskDefinition(CustomFieldType.Text, ExtendedAttributeTask.Text1, "Task City Name");

//Add it to the project's Extended Attributes collection

//Add a task to the project
Task task = project.getRootTask().getChildren().add("Task 1");

//Create an Extended Attribute from the Attribute Definition
ExtendedAttribute taskExtendedAttributeText1 = taskExtendedAttributeText1Definition.createExtendedAttribute();

//Assign a value to the generated Extended Attribute

//Add the Extended Attribute to task

project.save(dataDir + "PlainTextExtendedAttribute_out.mpp", SaveFileFormat.MPP); 

Other Improvements

  • Working with Extended Attributes of the API
  • Lookup values error while assigning to task
  • Large file size after creating task baseline
  • Saving Extended Task Attributes to output MPP
