Hello!

Recently I've discovered that binding to objects, on which Object.freeze was ran did not work, with some weird error about proxies.

I've put together a simple repository to demonstrate this issue here.

A workaround is to import such objects directly as separate modules, but in this case no binding to them is possible.

I find this concept useful, because it also insures runtime immutability, when things get boiled down to plain JS, you can never be to cautious of side effects there.

Please let me know if I am missing something or if anything else is needed.

Any help is appreciated.

Hi,

I've noticed if you invoke model.arrayProp.sort() it wraps the array objects in a proxy and it continues to do this with each call. If the sort is in a function and it gets called multiple times, the array objects continue to be nested in more and more proxies, which after a couple of calls causes ui5 to completely freeze when accessing them.

Am I doing something wrong? Any help on this is greatly appreciated.

Best regards,

Dimitar

We found this and decided to take it up for a test because we liked the idea and the implementation seemed neat. However when doing an aggregation binding, ui5 breaks during an attempt to call slice.

Changing the makeProxyFor function to this removes the error from the console

Am I missing something? Thanks for the support!
