Firefox Issue TypeError: b.nativeSelection is null

[Themonkey180]

This came up recently when the page is loaded. It gives me this error from firebug:

TypeError: b.nativeSelection is null
wysiht...2581355 (line 299)

After the page loads it does not show anything where the text area is supposed to be. An help would be nice.

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
