BPM: Creating Execution listener: DelegateExpression problem

[stasmakarov]

Environment

Jmix version: <2.3.4>

Bug Description

It is impossible to enter a delegate expression when creating an execution listener:

Steps To Reproduce

1. Create a process with any task (let it be script task)
2. Add an execution listener
3. Select type Delegate expression

Current Behaviour

The field "Delegate expression" looks like ComboBox, but it must be simple text field. So it is impossible to enter an expression here.

Expected Behaviour

The user must be able to enter the delegate expression like ${small.MyBean.print()}
