Hi! i created a cdt with an imageID then in an interface i designed a file upload with the target pointing to a documents folder and a save into and value of ri!product.imageId, now on an approval interface i want to display those images, i tried this:  a!documentImage(todocument(tointeger(ri!product.imageId))).document but i get this as an error: Interface Definition: Expression evaluation error at function a!imageField [line 77]: An image gallery component [label="Item's Pictures"] has an invalid value for "images" at index 1. None of the values in "images" can be null.  Is it because i didnt save to the database yet or another problem?

I have a table have 50 columns, but i only need change one column of information of certain rows, i don't want to saveinto every column one by one, but one save that only columns, what shall i do for coding but not process model? Thanks

disabled:if(isnull(local!searchDeleteUserRole),true(),if(isnull(trim(rule!KONE_Development_userrolebackupexist_Rule(local!searchDeleteUserRole))),false(),true())), my rule is: a!queryEntity( entity: cons!KONE_Development_userrolebackup_Constant, query: a!query( pagingInfo: a!pagingInfo( startIndex: 1, batchSize: 5000 ), selection: a!querySelection( columns: { a!queryColumn( field: "name" ) } ), filter:a!queryFilter( field:"name", operator:"=", value:ri!name, ) ), ).data What I test from rule is always return empty, which I doubt is null value, however, if(isnull(rule!(local!value)),true(),false()), it should return true() since no value respond in the rule, but seems it always return false, so i doubt the rule always return with some not null value though it is empty. Which way I can make the empty value transfer to be null? Thanks
