Constant crash when debugging on localhost (iOS only)

When debugging locally on simulator or device, I constantly get this redbox error:

ExceptionsManager.js:84 Exception thrown while executing UI block:
*** -[__NSArrayM setObject:atIndexedSubscript:]: object cannot be nil

Is this a known issue? I’d be happy to look into it, but I wanted to check if anybody was aware of it so far. It makes debugging very difficult.

Getting somewhere! If I remove the call

[nodesManager operationsBatchDidComplete];

in REAModule.m, the exceptions stop throwing. Looking at the documentation for (void)operationsBatchDidComplete in REANodesManager.m, it doesn’t seem like this call is absolutely necessary, and I’m not noticing any performance issues from the slightly deferred callback.

@kmagiera Would you mind weighing in on this? I can do a PR with the line removed, but it would help to know more about why it’s there and whether there are any conditional checks we could run instead of removing it.

Error was confirmed when I was using setValue() inside PanGestureHandler event callback. It seems like calling setValue() on a very frequent manner does cause this issue. Hopefully this can be addressed in a better form than fixing the .m file.
