rendering not working #11

Closed kraftpunk97-zz closed 5 years ago

kraftpunk97-zz commented 5 years ago

While working on the module, I discovered that calling the WebIO's display function gives an error.

display(ctx.s)
ERROR: UndefVarError: HandlerFunction not defined

Is this error reproducible?

leaving this issue closed until further testing to avoid the possibility of a false alarm.

We see the same error, do you remember how you resolved it?

kraftpunk97-zz commented 5 years ago

@baggepinnen Yeah. The way I over came this, is by using Blink instead of WebIO. In the README.md example, simply uncomment the two lines after the call to the display function.

It's not great, but we're working on it.We hope to get a better rendering system within a week; two at most.

@baggepinnen when you're using the Blink method for rendering, do not call display
