I read something about accessing the shadowDom but i didnt unterstand what they where talking. <html> <head>

The problem is that I cannot select the input element until the template has loaded. Currently, I am just using setTimeout to focus the input 100ms after the template should load, but I want to know if there is a more elegant solution. Also, the autofocus attribute doesn't work, because the template may un-stamp and re-stamp many times. Right now, my code looks something like this (this is inside a polymer element definition):

I haven't done anything besides creating the template for 3.0 and adding the import. There seems to be an issue with the Migration Tool , Google used to update their old components. Has anybody sorted this already? 回答1: UPDATE The issue is caused by two different versions of iron-meta in node_modules : an older version in ./node_modules/@polymer
