CBTA check existence
I would like to ask you if there is a way to check by CBTA components if some element, for example button or label on html page, already exists? I try to automate a process with a lot of different variants of process flow and this functionality would definitely help. So far I tried to use CBTA component for getProperty but I always fail because URI cannot be found if element does not exist on page. So my question is if there is a way to determine whether element from URI can be found or not. Therefore I could be able to alter automatic script flow.
Thank you in advance for your help.
