Waiting for Frame to load.

Question

I am currently encountering an issue from time to time in my scripts about not having permissions to access the frame.contentDocument.readyState.&nbsp; It is never in the same place or in the same script.Has anyone else ran into this issue?&nbsp; If so, how did you solve for it?Here is the code that I am executing.Do While GetTickCount() &lt; stopTime&nbsp;&nbsp;&nbsp; frames = page.FindAllChildren("ObjectType", "Frame", 5, True)&nbsp;&nbsp;&nbsp; If UBound(frames) &gt;= 0 Then&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; waitFrame = False&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; For i = 0 To UBound(frames)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Set frame = frames(i)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Do While frame.ContentDocument is nothing&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; aqUtils.Delay(100)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Loop&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; If frame.Exists And frame.contentDocument.readyState &lt;&gt; "complete" Then&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; waitFrame = true&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Exit For&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; End If&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Next&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; If Not waitFrame Then&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Exit Do&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; End If&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; aqUtils.Delay(1000)&nbsp;&nbsp;&nbsp; End If&nbsp; Loop

Hi Ted,I think that the problem is caused by the fact that VBScript does not support short-circuit evaluation of the logical expressions and always evaluates all conditions even if it is not necessary.So it is possible that&nbsp;frame.contentDocument may exist but its readyState property is not accessible yet.I would suggest to modify your code like this:instead of:&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; If frame.Exists And frame.contentDocument.readyState &lt;&gt; "complete" Then&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; waitFrame = true&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Exit For&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; End Iftry this (not tested):&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; If frame.Exists&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Do While Not aqObject.IsSupported(frame.ContentDocument, "readyState")&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; aqUtils.Delay(100)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; Loop&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Do While&nbsp;"complete" &lt;&gt; frame.ContentDocument.readyState&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; aqUtils.Delay(100)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; Loop&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; waitFrame = true&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Exit For&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; End If
