We have support for data-wisej but it’s not completed. If you look inside wisej.js you will find the function createEmbeddedControls. It will work like this:
It creates in inline root (qooxdoo widgets are hosted on a root container always, there is one for the entire application and then you can have inline roots for custom element, which is what we use to host controls in datagrid cells) in the div and places the control in there.
If you call Wisej.Core.createEmbeddedControls() manually you can test it. The outstanding issue is the lifetime of the component. Now it’s not rooted to the GC will destroy it.
So, the short answer is not yet. 🙂
