Document uploads on gridLayout
saileshd
over 7 years ago
I have a gridLayout where I am uploading a document to each record. If the Docuemnt is already uploaded to the record it displays my grid, but if the document is not uploaded it gives an error as below:
"Could not display interface. Please check definition and inputs.
Interface Definition: Expression evaluation error in rule 'icams_editlogisticsgroupeditmoduleitemroweach' at function a!applyComponents [line 195]: Invalid index (1) for list: valid range is empty"
Any Suggestions?

Be aware with using isnull on arrays. (whether CDT or primitive array).
If the variable used for the array is actually null, then null will work as expected and return true.
But, if the array is just empty (but not null), isnull will return false.
If not kept in mind, this error may cause unintended behavior.
