Champion Level 2TypeError: Cannot read property 'Navigate' of null
I accidentally deleted all of the namemapping objects.
and after setting the back up back into testcomplete i keep getting this error with every step.
This happens at the very first step.
JavaScript runtime error.
TypeError: Cannot read property 'Navigate' of null
TypeError: Cannot read property 'Navigate' of null
For the web application I'm automating, extended find is disabled,
I only map the names for the controls I'm interacting with only - e.g. right click on the control and select Map Object
Select the last option
I let TC choose the default names, but the last item name I change to something meaningful. Once my objects are all mapped, I then drag them into Aliases mapped object to build a tree structure
I do scripting, and this is the best method I have found, that works for me. I also use TFS as source control.

KB1Yess, I did all the namemapping over again.
Thank you for this tip

Something is using the word "Navigate", which hasn't been initialised, and TC doesn't like empty values. You'll need to find this and correct it.

All my name mapped objects are gone.... how do I fix this?
- rraghvani
From your screenshot, you do have name mappings. I'm guessing the references have been broken, which most likely means you'll have to delete and recreate the name mappings again.
If you click on Update, on the name mapping, does it update correctly?
Unfortunately, there's no other ways of recovering this, if you're not using source control or have Windows file history enabled.

No it does not update it only shows red. and hours and hours of testmaking is just down the drain.....
what is a fast way to get all the name mapping right?
- rraghvani
I forgot to mention, I don't use XPath in my projects
- KB1
Is there a reason why you don't use xPaths? is there a simpler way to point to objects in testcomplete? In my environment some Fields got the same label or id.
- rraghvani
I don't do cross browser testing, and our tool only supports Windows. I also found xpath not being able to identify the exact UI objects I wanted - majority of all out UI object don't have ID's.
