index or not in source file

We use Cornerstone to compare text files in our project
It often points out differences that are not, like an index addition
For example on a button action, the program sometimes has an index parameter and sometimes not … (see picture :slight_smile:

With the other developers we use exactly the same version of xojo (2016r3) but this anomaly exists since REALbasic.
We compared our preferences without seeing any difference, and Xojo reopens both versions, no effect on behavior.

What can I do to stop having this problem?

the “index” parameter appears when the control in question is a control set… even if that control set only contains one control

check the code that shows an index, and make sure that this is not the case…

I have never seen “index” appear except in this situation

yes this button has an index, since many years…

depending on whether the window is examined by one or the other developer, when it saves the project, the index parameter is absent or present …

NB in the source of the action, “index” is used and it compiles, whether the parameter is there or not.

I have seen this happening multiple times when comparing files to be commited with git.
However it’s some time I don’t see it anymore since some time, maybe this is fixed with newer versions.
