Set assignee null


I have a variable in the assignee I would like the value of it to be null, but if in the form I do not specify any value for this variable it assumes the value “” (white) and not null then I can not take over the task I can only appropriate The value of assignee is null.


you are using Embedded Forms?



What I want to do is the following, in the form the user has the option to send the task to a user from a list or to a group, when he chooses to send to a group I want the value of the assignee variable to be null so that one User of the group I can appropriate, only that the variable is going in arm and not null of it gives error in the time of the appropriation
