Hi @Sudharsan_AIT ,
Quick workaround: please try to put an IF statement before your check:
if isnull(one_variable.isvisible) then consider it as false because as you say “the element is not appeared on the screen”.
However, this is just a quick-fix and does not explain why this happens. One thing you could look at is if another element on the screen behaves in a similar manner or it is just this one. If multiple elements behave like this - it may be a problem of how you read and what you keep in that “one_variable”. What type is it and how do you initialize it?
Also, you may check with UIExplorer for another element on the screen what value the isVisible property contains. Could it be 0 or 1 instead of true/false?
Let us know. Thank you,
