I am trying to test the functionality of performing operations in cells present in a workbook based on test cases specified by customer.
The operation could include editing a cell or range of cells corresponding to a specific row or column.
The problem is with the format of the workbook. This workbook is present in an application that is accessed as a jnlp file. When I use click option to indicate element , the whole sheet gets selected as Target as shown in the attachment.
Then your problem is not an extension problem. The library used to build the app is a custom one, written on top of Swing. That JGrid element is the one with the problems.
Can you use the UiExplorer and indicate the element again?
Can the node from the UiExplorer tree be expanded? Does it have any children? (screenshot would help)
Also, is there any fullClassName property in the property explorer section of UiExplorer?
That JGrid element is a custom element built on top of a standard JTabbedPane (most probably) from Swing. Somehow, it overrides the default behavior when reporting dimensions of itself and of its children.
In your case, Studio uses AA framework with ctrl selectors to identify elements, not the Java extension. If switching the UI framework using F4 does not help identify the elements better, then CV is the only solution left.
