Is it possible to give a service a dynamic number of input?
I have two group of things:
group A: structures (100 things)
group B: element (created by the user)
In my mashup I have two lists widget, one for group A and one for B.
Since the user may create the element thing, the group B will be update time by time. The user must also be allowed to assign a structure to an element:
I created a helper thing with a service which has as input structureName and elementThing.
By selecting the element name and the structure name on the lists a property called "elementFather" in structure will be updated with the name of the element thing.
This works.
What I want to do is a multiselection of structures.
Since several structures may be assigned to a single element I would like the user, instead of doing it one by one, may do a multi selection from the list but this means that my service has a higher number of input which change time by time OR that my input structureName is not a string but an array.
Is this possible?
You should activate MultiSelect on List or Grid widget, then use SelectedItems property and bind it to the Service which adds the relation, this service needs a parameter to be Infotable type in order to receive multiple rows selection.
