Action-confirm and let widgets

Hi @jypre I’m afraid that is a lot of code to read. Is there any chance you can reduce it to a minimal test case?

@jypre

However, note that the problem is that the first evaluation (which happens alng the lines that @jeremyruston hinted, leads to a javascript error that stop the rendering with a big ugly dialog box of error! So my main concern is to avoid this to happen

JS errors are, by definition, a bug in the core. It is not supposed to be possible to induce a red screen of embarrassment purely in wikitext so it would be worth chasing this down.
