Branching workflows in custom_instantiation.cfg?

System

We are having issues branching our workflows down different paths using the formapi in the custom_instantiation.cfg

the issue is with the javascript function >>> var workArea =IWDatacapture.getWorkarea(); does not return the full path which the branching code needs

pretty much are are using IWDatacapture.getWorkarea();to get the path

for example - if path = //SERVER/default/main/A/ > if the subfolder A is submitted, getWorkarea only returns //SERVER/default/main/

however, if //SERVER/default/main/A/test.html is submitted, getWorkarea returns //SERVER/default/main/A/

we need the full path folder level to do our workflow branching properly. any thoughts/ideas?
