Posted on by Sascha2

I have a piece of code which was definitly working fine 2 days ago, now is completely broken. I have tackled it down to be a broken funcktionallity in Combination of "ForAll" and "ThisRecord". I have prepared a simplified code snippet to show the issue:

ClearCollect(Collection1;Table({ID:1};{ID:2};{ID:3}));;
ClearCollect(ItemsToRemove;Table({ID:2}));;


ForAll(ItemsToRemove;
 Notify("ID of Record of ItemsToRemove-Collection:" & ThisRecord.ID & " - this is correct." & Char(13)&
 "ID of Looked up Value in Collection: " & First(Filter(Collection1;ID=ThisRecord.ID)).ID &". This is incorrect. Should be 2, not 1" 
));;

Put this snippet on a button and you will be able to reproduce the issue.

I am pretty sure this is a major bug which was introduced within the last 48 hours.

This has enourmos impacts. LookUps / Filters / RemoveIf to a SQL Server Database will have the exact same issue and affect random records. Due to this, our Canvas App is currently deleting random records from a SQL Server Database instead of selected ones.

Hi @Sascha2

It might be something to do with the nested 'ThisRecord' which is causing conflicts.

Can you try redefining your source using the 'As' function, so you can use something other than ThisRecord and potentially avoid conflicts - in this example I have just called it 'ITR'

ClearCollect(Collection1;Table({ID:1};{ID:2};{ID:3}));; ClearCollect(ItemsToRemove;Table({ID:2}));; ForAll(ItemsToRemove As ITR; Notify("ID of Record of ItemsToRemove-Collection:" & ITR.ID & " - this is correct." & Char(13)& "ID of Looked up Value in Collection: " & First(Filter(Collection1;ID=ITR.ID)).ID &". This is incorrect. Should be 2, not 1" ));;

Hope this Helps

Thanks, indeed using the Alias here seems to solve the issue. I'll implement that. Thanks so far.
