Hello,
I'm trying to run the JSBridge callback example from a 4.5 image. JSBridge.st is loaded and I'm running under Chrome on Windows. I get an error: "Error:primReturnFromCallback: failed. " Digging a little in the debugger, I find in JSObjectProxy>>handleCallback, result is : "Error: Error: This block accepts 2 arguments, but was called with 0 arguments".
Modifying the example with a callback block with 0 arguments works.
The JSBridge demo on the SqueakJS site seems to be working fine.
Any ideas?
Thanks!
Jerry

Hi Jerry,
you found a bug :)
Apparently I’ve never tested this with block closures, only with block contexts.
I created an issue: https://github.com/bertfreudenberg/SqueakJS/issues/29 https://github.com/bertfreudenberg/SqueakJS/issues/29
But I think it’s going to be trivial to fix. We just have to handle both blocks and closures in js_primitiveGetActiveCallbackArgs(): https://github.com/bertfreudenberg/SqueakJS/blob/3c137c6f930259d0bcf02d5f80a... https://github.com/bertfreudenberg/SqueakJS/blob/3c137c6f930259d0bcf02d5f80a86ee1457f17fe/vm.js#L6010
