I have a JSF application with PrimeFaces that I'm updating to PrimeFaces version 8 (currently using version 7).
After updating I have a strange behaviour with a TextEditor in a dialog. I open the dialog with a commandLink and update the dialog to refresh its contents. When I do this I get an error on the JavaScript console.
texteditor.js.xhtml?ln=primefaces&v=8.0:7 Uncaught TypeError: Cannot read property 'innerHTML' of null
at e.value (texteditor.js.xhtml?ln=primefaces&v=8.0:7)
at new e (texteditor.js.xhtml?ln=primefaces&v=8.0:7)
at texteditor.js.xhtml?ln=primefaces&v=8.0:7

at texteditor.js.xhtml?ln=primefaces&v=8.0:7
at Array.forEach (<anonymous>)
at e.value (texteditor.js.xhtml?ln=primefaces&v=8.0:7)
The error comes from the code:
a(e.prototype.__proto__ || Object.getPrototypeOf(e.prototype), "selectItem", this).call(this, t, n), t = t || this.defaultItem, this.label.innerHTML = t.innerHTML
where t is null so t.innerHTML throws the error.
However - if I only open the dialog but don't udpate it - everything works fine.
I created a minimal sample. First fink works fine, second link creates the error.

<p:commandLink value="does not work"
oncomplete="PF('dialogTemplateSendMailToPersonVar').show()"
update=":templatePersonSendMailForm"/>
</h:form>
<p:dialog id="dialogTemplateSendMailToPersonId" widgetVar="dialogTemplateSendMailToPersonVar" dynamic="true">
<h:form id="templatePersonSendMailForm">
<p:textEditor id="txtTemplateText" />
</h:form>
</p:dialog>
</h:body>
</html>
In this sample the update is useless, but produces the same error as with my full page where I have backing beans that fill the editor and other fields in the dialog.
Has anybody experienced something similiar or any idea how to fix this? I checked the release notes for the PrimeFaces 8.0.x versions, but didn't see any issue with TextEditor. Not updating the dialog is not an option ;-)
