Make Changes in Project Extended Attribute with Aspose.Tasks Cloud 18.9

Aspose.Tasks CloudWe are pleased to announce the new release of Aspose.Tasks Cloud 18.9. This release made changes in ExtendedAttribute type. Added fields such as ‘DateValue’, ‘DurationValue’, ‘NumericValue’, ‘FlagValue’ and ‘TextValue’  and removed fields such as ‘DurationFormat’, ‘Value’ and ‘AttributeType’ fields. Moreover, a few bugs were fixed. For a detailed note on what is new and fixed, please visit the release notes section of APIs Documentation.

Important Changes and New Features

1. Duration type was added:

"TimeSpan": "10:00:00",
"TimeUnit": "Hour"

2. Changes in ExtendedAttribute type

Changes in ExtendedAttribute type (used in Task.ExtendedAttributes, Resource.ExtendedAttributes, ResourceAssignment.ExtendedAttributes collections):

  • ‘DurationFormat’ field was removed
  • ‘Value’ field was removed
  • ‘AttributeType’ field was added
  • Following fields were added: ‘DateValue’, ‘DurationValue’, ‘NumericValue’, ‘FlagValue’, ‘TextValue’

The following table shows which field contains the value of extended attribute depending on ExtendedAttribute’s type. Thus in order to get or set the value of a custom field with ‘Date’, ‘Start’ or ‘Finish’ type one should use ‘DateValue’ field.
