Trouble with system.vision.openFiles

Ignition
1

Hi everybody, I’m very new to Ignition but I’m loving it so far! I have, however, ran into a weird problem. I’ve got a button I want to use to open up a specific folder to list the files that the folder contains. I’ve been testing with the system.vision.openFile function, this seems to work well but does not open a folder, it opens a specific file (as it should). I wanted to use the system.vision.openFiles function but I can’t get it to work at all, according to the Vision User Manual it should work the same as the system.vision.openFile function but I keep getting hit with an argument error: caused by IllegalArgumentException: extension is not a valid keyword for openFiles. Does anybody know why this is?

Thanks in advance!

Can we see the function call with the arguments you are supplying?

Don't use keyword arguments except where support is explicit.

Hi Greyship, thank you for responding. The function and arguments:

paths = system.vision.openFiles("xlsx")

This returns Traceback (most recent call last):
File "event:actionPerformed", line 5, in
java.lang.IllegalArgumentException: java.lang.IllegalArgumentException: extension is not a valid keyword for openFiles

caused by IllegalArgumentException: extension is not a valid keyword for openFiles

And when I use the function without arguments it returns Traceback (most recent call last):
File "event:actionPerformed", line 5, in
java.lang.IllegalArgumentException: java.lang.IllegalArgumentException: extension is not a valid keyword for openFiles

caused by IllegalArgumentException: extension is not a valid keyword for openFiles

Thanks for your help.

Hi pturmel,

Maybe I misunderstood (English is not my first language) but in the User Manual for both functions it would seem like I can use the same arguments. Is this maybe a mistake in the User Manual or am I simply not understanding the text?

openFile: system.vision.openFile | Ignition User Manual
openFiles: system.vision.openFiles | Ignition User Manual

Thanks in advance.

This looks like a bug, the keyword is “extensions” in the function prototype, but the back-end is trying to validate the keyword as “extension” and failing.

Both of these calls fail:

system.vision.openFiles("xlsx")
system.vision.openFiles(extensions="xlsx")

Gentlemen, thank you for your time and help.

I decided to use a depricated function:

paths = system.file.openFiles("xlsx")

This function is old but does work.

Thank you both.

Should this be reported to Inductive Automation?

I would open a support ticket, yes.

IIRC, a number of documented system.vision.* functions for v8.3 aren't actually ready.
