For example, Microsoft Dynamics NAV application shows customer No and Name in the title of the edit window.
When we do recording and capture Name field - it's properties contain window title.
If, for example, Name of the customer will change or we'll create a data-driven test that will reuse same Name object for testing different customer records then object recognition will be broken.
To match window titles for different customer records we need to use a regular expression.
regex:Edit - Customer Card.*
Now Rapise will match Name object in any window that has name starting with Edit - Customer Card
Note: This is an artificial example. Rapise has special support for Dynamics NAV and during recording generates regular expressions for window titles automatically.
