‘’Assigned to‘’ the project

when I create a new task, the gantt app shows me the message that:

and the lightbox section will show the owner’ s name. This’s right !
But when I serialize the gantt data, the task’s owner will be ‘Bill’. That’s wrong! I want the gantt app thow the owner’s name ,but serialize the owner’s id which is saved in the database. Please help me!

Hello Feng,
That depends on the key parameter: when it contains a number, the task property will have a number, if it is a string, you will see the string:

In our samples, the key parameters have number values.
