While loop keeps on throwing an error

My while loop was setup as such:   While (Object_A.VisibleOnScreen=True AND Object_B.VisibleOnScreen=False) { Delay = 2000ms, "Reloading..." }   Note: Object_A appears before Object_B, they do ...

    Hi,

     

    You want to suppress the error when that object not exists in the screen since you are expecting object will get visible on the screen after some time.

     

    If my understanding correct, before checking VisbleOnScreen you need to check the Exists property in-order to suppress the object not exists error in the TC logs.

     

    Like below,

     

    if(Object_A.Exists)
{
    Object_A.VisbleOnScreen;
}

Correct... you cannot check any propertype of an object if it does not exist.

You can consider using WaitChild or WaitAliasChild in your while loop conditionals. These will allow you to use the VisibleOnScreen property for your validations but, honestly, even with the Wait methods, you probably would be better checking Exists rather than Visible onscreen

    Just an FYI, I'd write your code more something like the following.  Note, I'm assuming you're using NameMapping and that ObjectA and OBjectB have the same parent object.

     

    While ((parent.WaitAliasChild(Object_A, -1).VisibleOnScreen) && (!parent.WaitAliasChild(Object_B, -1).VisibleOnScreen)) {
Delay = 2000ms, "Reloading..."
}

    As noted above, it might be better to check "Exists" rather than "VisibleOnScreen" as it sounds like it's more a matter of existance than visibility that determines what's going on with the objects.  But, for demonstration purposes, I'm posting code similar to what you originally posted.
