Hi All,
the ToolValidator documentation says:
As a Value object does not support string manipulation, use the Value object's value property whenever a string is to be manipulated or parsed. The code sample uses the os.path.dirname method to return the directory from a dataset.
However, the following works fine:
My question are,
1. Has anyone encountered a situation where they DID have to use self.params[0].value.value and self.params[0].value wouldn't work?
2. Is this working because I'm running 10.2? Does it work for those of you that have 9.3, 10.0, and 10.1?
I have a dummy script tool with 1 param. The code below is for debugging outside the script tool. It also works inside the script tool (I set a second param to that value to check it in the script tool). Here's a complete script to test this:
It runs successfully and prints:
C:/Temp
The documentation is about midway through the following page:
