We want to confirm if Teamsite 8.1 supporte to replace TinyMCE with other WYSIWYG content build editor (for instance http://innovastudio.com/content-builder.aspx). HP(Opentext) support team said no but our stuff used it in the previous company. It is interesting.
They are the final arbiters of what is supported.
Can you do it ? Possibly. Shouldn't be horribly difficult, but you will be on your own if you try and will have to figure out how to make ti work and how to support it.
Understand. I find there are three JS files under datacapture/richtexteditor/. I doubt there may be other configuration files. Anyway, it is possible but not easy and supported by OpenText.
