ID 426569 - Render node outputs not updating correctly in Parameters tab when appearing in a TeleParameter

Problem summary:

When setting up a TeleParameter to show the outputs parameter of a Render node in the parameter interface of a Group node (e.g. a custom SuperTool node), the list of render outputs is not always updated correctly in the UI.

Steps to reproduce:

1. Execute the following snippet of Python code in a Python tab:

   • 
     groupNode = NodegraphAPI.CreateNode('Group', NodegraphAPI.GetRootNode())
     cameraCreateNode = NodegraphAPI.CreateNode('CameraCreate', groupNode)
     renderNode = NodegraphAPI.CreateNode('Render', groupNode)
     cameraCreateNode.getOutputPort('out').connect(renderNode.getInputPort('input'))
     outputsParameter = renderNode.getParameter('outputs')
     outputsTeleParameter =  groupNode.getParameters().createChildGroup(
         'outputsContainer').createChildString('outputs', '')
     outputsTeleParameter.setExpression('getParam("%s").param.getFullName()'
                                        % outputsParameter.getFullName())
     outputsTeleParameter.setHintString('{"widget": "teleparam"}')
     NodegraphAPI.SetNodeEdited(groupNode, True, True)

2. In the Parameters tab, open the outputsContainer group parameter, and inspect the contents of the outputs parameter inside.

Expected behavior:

The outputsContainer.outputs parameter of the Group node shows 1 render output: primary

Actual behavior:

The outputsContainer.outputs parameter of the Group node is empty.

Workaround:

Flush caches.
