Assigning form field value to array

[hheckel]

Hello,

I initialized an array using a groovy script

def names = ["Miller", "Smith", "Jones"].toArray();
execution.setVariable("names", names);
‍‍‍‍

Now, I am wondering if in Activiti Explorer I can assign/overwrite a value through assignment in a form field using the following configuration in a subsequent task:

Form property configuration:
Id: assignNewName
Name: Assign a new name
Variable: names[0]
Readable: True
Writeable: True
Required: True

Thanks for your input!
H.

Yes it can… Use the "expression" instead of variable field:


<activiti:formProperty id="newName" expression="${names[0]}" required="true" />

Thanks!
