KB197367249: WebCenter - String length in Execute JavaScript workflow node

Summary

If you use .length in, for example a text attribute value in the WebCenter Execute JavaScript workflow node, it always returns 0.

Symptoms

For example: the following script reads the value of the attribute Text but has unexpectedly 0 in the variable length:

  1 var project = API.getProject();
  2 var attr = project.getAttribute("Text");
  3 var value = attr.getValue();
i 4 var length = value.length; // always returns 0

Solution

• Convert the value to a native JavaScript string first (see line 3):

    1 var project = API.getProject();
    2 var attr = project.getAttribute("Text");
    3 var value = "" + attr.getValue();
  i 4 var length = value.length; // returns the correct length

  
  

• Upgrade to WebCenter 18.1 where this issue will be fixed
