That Length formula doesn't work.
I put the following code in the top of my page.
ProcessOverview Value = "$doc.getValue('processOverview')"
ProcessOverview Length = $doc.getValue('processOverview').length()
I then put a value of "a" in the processOverview textArea and saved it. The
result is below:
<http://xwiki.475771.n2.nabble.com/file/n7589776/ProcessOverview_With_Value.png>
I then emptied the processOverview textArea of anything and saved it. The
result is below:
<http://xwiki.475771.n2.nabble.com/file/n7589776/LengthStill1.png>
I was wondering if the system is inserting a carriage return or something in
the empty field. So I looked at the HTML code and it only has a <p> node
above the empty text node.
