The length seems ok : from your screenshot, it seems in second case your string contains a blank space " " and not an empty string. So you could first trim() it then compute length() (though I admit I don't know from were comes the blank space in second case). 2014-03-24 18:15 GMT+01:00 DeHaynes <[email protected]>:
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:

I then emptied the processOverview textArea of anything and saved it. The result is below:

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.
