Load navigation state

[f1ymann]

Hello, sorry for bad english. I`m trying to implement save/load support for my application using imgui node editor. In functions LoadSettings and SaveSettings passed into Config object I realized configuration saving and loading, this is example of json file which I got: {"nodes":{"node:1":{"location":{"x":183,"y":56}},"node:3":{"location":{"x":209,"y":250}},"node:5":{"location":{"x":447,"y":178}}},"selection":null,"view":{"scroll":{"x":517.49993896484375,"y":244.499740600585938},"visible_rect":{"max":{"x":660.2000732421875,"y":360.599945068359375},"min":{"x":207,"y":97.7999038696289062}},"zoom":2.4999997615814209}}"} On loading this json correctly parse and settings applies for internal objects, but on next Begin I got called m_Canvas,SetView for m_NavigateAction containing default values. What can be issue? P.S. Gteat thanks for your job, this is amazing library!

Thanks. Can you confirm that you're using at least version from master? Preferably from develop. There was a bug related to restoring state that was fixed recently.

I have used latest version from master and now tried latest developer version, there is same issue

Can you provide repro. Or step by step info of what functions are called and what your app do? Less guessing I have to do, better chance of fixing the issue is. : )

I tried to create simple example showing my issue using blueprints example, but recreated imgui enviroment (library version, and windows settings) i couldnt reproduce this error. So i cut node editors part of my project and commited it here https://github.com/f1ymann/rt-test-load.git , maybe you can find what was the reason of this problem. I found that on next frame after loading node editor context from config starts handling of canvas size change and in used in NavigateAction m_NavigateAction variable m_Zoom resets to 1.
