Moving a imported-template trigger a reload of the content

[ivarbergman]

Hi!

I have a situation where I need to move a div to another parent in the DOM.

Polymer.dom(newparent).appendChild(div);

This div contains a imported-template element. And when the div is detached and later attached back to the dom. The imported-template reloads the content by calling _importHTMLImport.

Is there some way that the re-loading of the content could be avoided?

I guess an analogy, would be the script tag. Moving a script tag does not re-evaluate the script.

Cheers!

@warpech we need to decide whether it's a bug/feature/feature that we would liek to change.

I would say it's desired behavior, as it is a convenient way to remove whatever was stamped from it. Detaching imported-template removes also all the stamped nodes. So the analogy is Polymer's dom-bind.

Why would you need to move this element? maybe just to make it easier and cleaner you can just distribute it within Shadow DOM?

The only solution that may somehow fit your need, and our idea of detaching, is that once re-attached imported-template would re-attach its stampedNodes as well, but it may require some time to implement.

I have described my idea at #24.

@ivarbergman Please, take a look it such re-stamping nodes fits your need.

Closing as it's pretty old and stale. Please feel free to re-open if there is anything more.
