Proxy from XML is inavailable from Python

Hello, dear Paraview developers

I have the following XML file

		<!-- Python fpr test -->
		<IntVectorProperty
		   name="Settest"
		   command="Settest"
		   number_of_elements="1"
		   default_values="0"
		   label="Settest"
		   panel_visibility="never">
			<Documentation>
				Python function for test obtaining.
			</Documentation>
		</IntVectorProperty>

		<!-- ParaView Mathieu, obtain value from the server -->
		<DoubleVectorProperty
			label="Gettest"
			name="Gettest"
			number_of_elements="1"
			default_values="0"
			command="Gettest"
			panel_visibility="never"
			information_only="1">

		</DoubleVectorProperty>

However when I do dir(filter) in Python only Settesest is presented, and Gettest is missing, why so?

I think it is because of the information_only attribute: this is a readonly property so we do not add it as an attribute of the python object

How could I use in in this case?

Actually you should be able to get it through proxy.GetProperty("read_only_prop"), or proxy.GetPropertyValue("read_only_prop")
