Description of problem:
If a service dialog has two text box elements, one static and one dynamically populated, the value from the dynamic element will not be passed to the service or button method if the static element is manually populated.

If the static element is left blank (default), then both element values are passed through. 

If the dynamically populated element's value is subsequently manually amended then its value is passed through.

Version-Release number of selected component (if applicable):
5.10.4

How reproducible:
Every time


Steps to Reproduce:
1. Import the attached BZ automate domain and dialog exports. The automate domain contains a method to populate the dynamic second element in the dialog.
2. Install object_walker automate domain from https://github.com/pemcg/object_walker
3. Add a custom button to a VM (or any) object. The button should use the newly imported BZ dialog, and should run object_walker when submitted (/System/Process: Request, Message: create, Request: object_walker
4. Click the custom button, and observe the dialog. The element 'Text Box 1' default value is empty, the dynamic element 'Text Box 2' has been dynamically populated. Submit the button, and observe the values passed through to object_walker - note that both element values have been passed:

~/object_walker_reader.rb | grep dialog
     |    $evm.root['dialog_text_box_1'] =    (type: String)
     |    $evm.root['dialog_text_box_2'] = The dynamic method ran at: 2019-05-30 09:42:40 +0100   (type: String)

5. Repeat step 4, but type some text such as "aa" into element 'Text Box 1'. Submit the button, and note that only the value from 'Text Box 1' has been passed through to object_walker:

~/object_walker_reader.rb -t 2019-05-30T09:43:25.558037 | grep dialog
     |    $evm.root['dialog_text_box_1'] = aaa   (type: String)

6. Repeat step 5, but now also amend the text dynamically entered into 'Text Box 2' (for example adding the string "also". Note that both element values are now passed through to object_walker:

~/object_walker_reader.rb | grep dialog
     |    $evm.root['dialog_text_box_1'] = ccdd   (type: String)
     |    $evm.root['dialog_text_box_2'] = The dynamic method also ran at: 2019-05-30 09:50:10 +0100   (type: String)

Actual results:
See above

Expected results:
All element values should be passed through to the underlying service or button method.
