Unable to start 2 or more smartservice at the same time

Good afternoon,

we have the following requirement and we are unable to solve it:

we need to launch at the same moment two smartservice (a!startProcess and a!deleteFromDataStoreEntities) from an interface when the user clicks on one single button "Delete", but the following error mesage appears:

Interface Definition: Expression evaluation error: An error occurred while executing a save: Expression evaluation error : Attempted to run a second smart service, but only one smart service can be run per expression evaluation. 

The interface is something like that

a!buttonwidgetSubmit(
value: true,
saveInto: {
a!save(ri!boolean, value),
a!startProcess(paraemter to start the process),
a!deleteFromDataStoreEntities(parameter to delete from datastore)
}
