Cannot read property '$el' of undefined after Tinymce editor instance remove()

[pderiy]

Hi,

I have angular-ui-router (this is router by frontend side). After leave page with tinymce editor I have to remove all ckeditor instances. And after second tinymce.init I have an error

Config:

tinymce.init({
      height: 150,
      lt_highlight_click: 'right',
      lt_lang: 'pl',
      lt_mode: 'new_word',
      menubar: false,
      selector: '#' + textarea.id,
      type: 'text',
      // statusbar: false,
      toolbar: false,

      external_plugins: {
        languagetool: '/js/libs/languagetool/plugin.min.js'
      }
    });

On page leave:

$onDestroy() {

      element('#fb-render textarea').each((index, textarea) => {
        tinymce.get(textarea.id).remove();
      })
    }

(It should remove all tinymce instances and it does)

After going back to the page it should call tinymce.init again

tinymce.init({
      height: 150,
      lt_highlight_click: 'right',
      lt_lang: 'pl',
      lt_mode: 'new_word',
      menubar: false,
      selector: '#' + textarea.id,
      type: 'text',
      // statusbar: false,
      toolbar: false,

      external_plugins: {
        languagetool: '/js/libs/languagetool/plugin.min.js'
      }
    });

But after second initialization I have an error:

I applied a fix in 0.31-Alpha, see if it works now.

Oh by the way, a minor thing but to note:(unrelated to the bug)

lt_highlight_click is "right" by default. you also don't need to use external_plugin and can load it as a normal plugin. The demo just uses external mode because I am loading tinymce from the cdn in the demo.

is okay now, thx.

Oh, good to know, thx)
