Title: Expression gives different results on UI versus API
Post by: zybex on January 22, 2021, 03:26:35 am

The API function GetFilledTemplate() seems to add an extra call to Clean() before returning the output. This causes the output to be different from expected, and different from what the same expression yields on MC's UI.

Examples:
file.GetFilledTemplate("test")      = "test"  (correct)
file.GetFilledTemplate(":test")     = ":test" (correct)
file.GetFilledTemplate(": test")    = "test"  (wrong)
file.GetFilledTemplate("test()")    = "test"  (wrong)

Simply outputting any field/value that contains () is also mangled:

Code: [Select]

save(/#test(), (), test2()#/, v_test)
[v_test]
This outputs "test, , test2" when using the API, and "test(), (), test2()" when using an Expression column on MC.

Can you please check and make the API return the same as the UI?
Thanks!

I just tried this URL:
http://localhost:52199/MCWS/v1/File/GetFilledTemplate?File=53728241&FileType=Key&Expression=%22:%20test%22

And I get:
<Response Status="OK">
<Item Name="Value">": test"</Item>
</Response>

Is this only the GetFilledTemplate(...) API function?

Thanks.

You're right that API calls add this:
JRString::CleanFilledTemplate(strValue);

Not sure why.  Let me dig a while.

I'll remove it from the next build.  Here's the history:
Fixed: Getting an expression with the API could perform extra (and unwanted) cleaning of the output.

Thanks for helping find this!

Thanks Matt! And props to Wer too, he bumped onto the issue on his first Zelda try :)
