Hi there,
there's a way to select an object and dynamically type in that object's location into the code.
How to proceed :
As long as your text cursor is displayed in the code, LiveCycle should automatically type in the location of that object within the JavaScript.
Note: if you scroll down in the design, the text cursor will probably disappear, so you should click once again in the code to ensure that your text cursor is rightly placed within your code.
Hope this will help!
