TinyMCE editor in UI page (Jakarta)

[Tommy Jensen]

Yet another question about TinyMCE editor.

I have added a UI Action to HR Case form that will display a dialog.

This dialog contains the TinyMCE editor.

First time I click on the UI action the Dialog opens and the ditor is initiated fine.

If I close the dialog then then click on the UI action again then the dialog opens but the TinyMCE editor is NOT rendered and there are no errors.
Then if I CTRL-F5 refresh the hr case form and click on the UI page the dialog opens with the editor back n place.

UI action to open the dialog looks like this:

function dialog() {
	var sysId = typeof rowSysId == 'undefined' ? gel('sys_uniqueValue').value : rowSysId;
	var gDialog = new GlideModal('sn_hr_core_dialog');
	gDialog.setSize(1800,600);
	gDialog.setPreference('sysparm_sysID', sysId);
	gDialog.setPreference('sysparm_table', g_form.getTableName());
	gDialog.setPreference('sysparm_subject_person', g_form.getValue('subject_person'));	
	gDialog.setTitle('Dialog');
	gDialog.render();	
}

and the first few lines of the dialog itself looks like this

<?xml version="1.0" encoding="utf-8" ?>
<j:jelly trim="false" xmlns:j="jelly:core" xmlns:g="glide" xmlns:j2="null" xmlns:g2="null">
<script>
   tinymce.init({
   mode : "specific_textareas",
   editor_selector : "mceEditor",
   width: '100%',
   height: '300px',
   menubar: "tools",
   toolbar: "$[gs.getProperty('glide.ui.html.editor.v4.toolbar.line1')]",
   content_css : "* {font: 10px arial, sans-serif;} b {font-weight:bold;} th {font-weight:bold;} strong {font-weight:bold;}",
   });
</script>

and finally adding the editor on the page:

<textarea cols="60" rows="10" id="textfield" name="textfield" class="mceEditor"></textarea>

Solution was to add a remove just before the init.

tinymce.remove('#email_body');

This is really weird. Yesterday the html editor worked fine.

today I am getting an error:

Uncaught ReferenceError: tinymce is not defined

Does anybody know how to initialise tinymce and or if a script include is missing?
