Given the following codeHere I am working with two windows - "nht" and "ac"nht exists and is visibleac exists and is NOT visible (It's completely hidden, not just behind another window)The problem is that line 146 (Check if ac exists) waits for the default timeout, even though it already exists!!To me, at least line 146 seems to be a bug.If the window does not exist and I execute the following codeThen it does not waitSo it's inconsistent.obj.Exists will NOT wait if the object does not existobj.Exists will NOT wait if the object exists and is visibleobj.Exists WILL wait if the object exists but is not visibleI'm not asking if it's invisible, I'm asking if it exists. Why should it alter it's behaviour based on a property I am not asking about?Whatever, what I want is to be able to perform both checks without waiting.I do not want to alter the default timeout, I want to be able to make just these specific checks without waiting.

I'm not sure what version of TC you are using. Since WaitTime is 0, WaitAliasChild will return immediately. Assuming the child alias object exists, then the property Visible will return a value immediately too. However, if the child alias object does not exist, WaitAliasChild will return a stub object immediately. Property Exists will return immediately, but Visible will return an error after a number of seconds - depending on the project auto-wait timeout. Ideally, you should enclose your Visible property within an If statement let ac = Aliases.ICS.WaitAliasChild("AddChannelWindwo", 0); if (ac.Exists) { let ac_vis = ac.Visible; }

WaitAliasChild does indeed always return immediately.Your statement "Property Exists will return immediately" is, however, incorrect (At least in my case)It will ONLY return immediately if the element is visible.If it's invisible, it will wait for the default timeoutWRT the enclosing of an if statement - yeah, in production code, I would indeed do that. For the sample code, however, I KNEW whether it would return true or false, I just did it that way to keep the sample code shorter

Using TC v15.55.53.7, here's a small example based on the website https://www.w3schools.com/jsref/tryit.asp?filename=tryjsref_style_visibility It returns immediately

RefreshMappingInfo() makes it worse. It causes the waitAliasChild() to wait as well.Here is proof that the issue is nothing to do with a quirk of the AUT.Example Java App:package com.example; import java.awt.*; import java.awt.event.*; import javax.swing.*; public class App extends JPanel implements ActionListener { private static JFrame childFrame; private static boolean secondFrameVisible = false; public App() { childFrame = new JFrame("Child Window"); childFrame.setName("Child Frame"); JLabel childLabel = new JLabel("This is a child frame"); childLabel.setPreferredSize(new Dimension(400, 400)); childFrame.getContentPane().add(childLabel); childFrame.pack(); toggleSecondFrameVisibility(); JButton toggleButton = new JButton("Toggle visibility"); toggleButton.setActionCommand("vis"); toggleButton.addActionListener(this); add(toggleButton); } private static void createAndShowGUI() { JFrame frame = new JFrame("FrameDemo"); frame.setName("Main Frame"); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setContentPane(new App()); frame.pack(); frame.setVisible(true); } @Override public void actionPerformed(ActionEvent e) { toggleSecondFrameVisibility(); } private static void toggleSecondFrameVisibility(){ secondFrameVisible = !secondFrameVisible; childFrame.setVisible(secondFrameVisible); } public static void main(String[] args) { javax.swing.SwingUtilities.invokeLater(new Runnable() { public void run() { createAndShowGUI(); } }); } }It looks like this - a main window ("FrameDemo") with a child window ("Child Window").When you click the "Toggle Visibility" button in the main window, the Child Window is set to invisible. Then create a Javascript project in TestComplete, add the following code to script Unit1:function debugme(){ Aliases.javaw.WaitAliasChild("Child_Frame").Exists; // <-- set breakpoint here Aliases.javaw.WaitAliasChild("Child_Frame").Exists; // <-- set breakpoint here Aliases.javaw.WaitAliasChild("Child_Frame").Exists; // <-- set breakpoint here Aliases.javaw.WaitAliasChild("Child_Frame").Exists; // <-- set breakpoint here }Run the sample Java appPut a breakpoint on line 2 in the TestComplete IDE (The .Exists line)Right click the function -> run this routineF10 to step - no waitClick the "Toggle Visibility" button in the sample app to hide the child frameF10 to step - WAITS!!Click the "Toggle Visibility" button in the sample app to show the child frameF10 to step - no wait

  It will ONLY return immediately if the element is visible.
  If it's invisible, it will wait for the default timeout
  
  WRT the enclosing of an if statement - yeah, in production code, I would indeed do that. For the sample code, however, I KNEW whether it would return true or false, I just did it that way to keep the sample code shorter

  I have managed to submit my zip to support via email (Case #00664059)
  Thanks for all your help so far!
  Oh, and PS, I am off work tomorrow, so unlikely to reply
