Writing data of different type (CON-24)

[ilya1725]

I have the following data structure defined in the XML file for commands:

<struct name= "MotorCommand">
  <member name="current_A" type="double"/>
</struct>

When I explicitly set the data as double, like this:

{'motor': [{"current_A": 25.0}]}

The command is being set fine. However, if the data is set like this:

{'motor': [{"current_A": 25}]}

it isn't sent. I use the

    self._command_writer.instance.setDictionary(command)
    self._command_writer.write()

python code to write DDS commands.

I have two questions:

1. Is it hard requirement that the data types in the dictionary must be exactly as declared in the XML file?
2. Is there a way to get some sort of error status from self._command_writer.write()? It is very inconvenient/dangerous for the API to just accept a command and provide no status back.
