Bug? cursor1.GetBlob("pic").length is missing

Hello,

for example:

Code:

log(cursor1.GetBlob("pic").length)

the ".length" is not displayed in the preview and if I want to print this through the log, then this error comes:

Code:

Error occurred on line: 2344 (Main2)

A null object has no length.

 

yes, but how should I check otherwise if it is NULL? under IOS the same code goes on a NULL object.

 

Code:

if cursor1.GetBlob("pic") <> null then
  log(cursor1.GetBlob("pic").length)
end if

 

Create a Variable to receive the result then check the length.

Code:

Dim pic as string
pic = cursor1.GetBlob("pic")
log(pic.length)
