Unpoly 2 support request

[szabesz]

Hello Adrian,

I am working on my very first Unpoly 2 driven frontend and found that either Tracy's or Unpoly's JavaScript break in some cases. I get errors in the console like this:

Uncaught TypeError: this.elem is null
    Panel http://mydomain.test/products/?_tracy_bar=js&v=2.9.1&XDEBUG_SESSION_STOP=1:29
    loadAjax http://mydomain.test/products/?_tracy_bar=js&v=2.9.1&XDEBUG_SESSION_STOP=1:444
    loadAjax http://mydomain.test/products/?_tracy_bar=js&v=2.9.1&XDEBUG_SESSION_STOP=1:442
    <anonymous> http://mydomain.test/products/?_tracy_bar=content-ajax.5de8b397b6_2&XDEBUG_SESSION_STOP=1&v=0.44454897717264863:1

 

The above example starts happening when I first use the browser's back feature. I tried to relocate unpoly.js to body's end from the head but to no avail. Either Unpoly breaks or Tracy's JS, depending on the loading order.

Note, that Unpoly recommends using its own event handling methods: https://unpoly.com/up.compiler as its automated event handling might interfere with "random JavaScript", as we probably see in this example.

Are you willing to deal with this issue? If so, what else should I do to help you make them work together?

Thanks in advance,

Hi @szabesz - I am heading on vacation tomorrow for a couple of weeks, so it will be a while before I can take a look at this. That said, I am not sure if I can actually do much about this. I actually wonder if this is something that should be raised over at: https://github.com/nette/tracy because I *think* it is something they would be better off fixing in the Tracy core.

I see. I will probably ask for help at the Unpoly repo first to figure out more and next ask the Nette devs as you suggested. Thanks!
