Firefox Issue TypeError: b.nativeSelection is null

[brunobg]

I've had that before. It happens only in firefox and this fixes the issue: tiff/wysihtml5#371

Thank you

What exactly is the fix? This seems like a bug that should still be fixed, and thus the issue should be re-opened. Regarding the referenced comments in xing#371, in many use cases, the textarea is hidden when the page loads (for example when a form is hidden with display:none, and is only shown after the user clicks a button, which is my use case). Also, the proposed fix in the rangy-core.js code (which has not been officially implemented in that library) has not yet been implemented in wysihtml5x either, as done here.

Moreover, the previous proposed fix eliminates the TypeError: b.nativeSelection is null; however, it does not eliminate a second error that occurs when the textarea is hidden during page load (in Firefox): NS_ERROR_FAILURE (on line: 12446): that.doc.execCommand("enableObjectResizing", false, "false");.

I was using wysihtml5 version 0.3.0 and there was no error related to this. The error was introduced in version 0.4.0 and still exists in the current versions.

@pulges I think this should be re-opened, don't you think? Even with the above mentioned fix, I still get an NS_ERROR_FAILURE when the form is hidden at page load, as mentioned above... This seems pretty critical...

I'm also hitting this, in a form that's brought in via AJAX, then initialised. Only seems to affect Firefox
