ID Known Issue
Controls and Indicators

Return
Radio Button Group does not resize when additional Radio Buttons are added

Workaround: N/A

Reported Version: 2.0    Resolved Version: N/A    Added: 01/23/2018
666287

Return
Warning when copying a Graph from a VI's Diagram to a Web VI's Diagram
When you copy a VI's Diagram contents and paste them on a Web VI's Diagram, a warning will appear if one of the items is a Graph indicator.

Workaround: Delete the graph terminal and create a new Graph in the Web VI

Reported Version: 2.0    Resolved Version: N/A    Added: 01/23/2018
666581

Return
Dragging multiple arrays into a tab control can cause visual issues

Workaround: Save the Web VI and reopen it, or drag a single element into the tab at a time

Reported Version: 2.0    Resolved Version: N/A    Added: 01/23/2018
736938

Return
Can't change value of control with duplicate terminals from the Panel
A control with a duplicate terminal on the Diagram can't have its value changed from the Panel.

Workaround: Right-click the duplicate terminal on the Diagram >> Change to read.

Reported Version: 3.1    Resolved Version: N/A    Added: 07/08/2019
External Code
673324

Return
Adding items to the FrontPanelCanvas
tags in the HTML panel always places the new items at the top of the section
Because the items that are added are always at the top of the section, the content that is added will always appear behind the content that LabVIEW NXG creates

Workaround: Set the z-index property for the item that is being added

Reported Version: 2.0    Resolved Version: N/A    Added: 01/23/2018
719781

Return
JSLI dependencies can't be located after changing their namespace in the project.

Workaround: 1. Reference the JS files relative to the component and not the JSLI doc (e.g. use "/javascript/Add.js", instead of "javascript/Add.js")
2. Close and reopen the project

Reported Version: 3.1    Resolved Version: N/A    Added: 07/08/2019
Functions, VIs, and Express VIs
664268

Return
VI snippets do not create controls on the Panel when placed in a Web VI

Workaround: N/A

Reported Version: 2.0    Resolved Version: N/A    Added: 01/23/2018
666182

Return
When attempting to create a sub VI from code on a Web VI, you can only create a sub Web VI

Workaround: N/A

Reported Version: 2.0    Resolved Version: N/A    Added: 01/23/2018
669020

Return
String to Number functions may return incorrect values when converting to I64 or U64 data types in Web VIs
When converting from strings to 64-bit numbers, the String to Number functions (Decimal String to Number, Hex String to Number, etc.) can return unexpected results

Workaround: N/A

Reported Version: 2.0    Resolved Version: N/A    Added: 01/23/2018
671454

Return
Providing a username and password when a cross-origin request results in a 401 has varying behavior between browsers. In the LabVIEW NXG editor this will result in a timeout.

Workaround: N/A

Reported Version: 2.0    Resolved Version: N/A    Added: 01/23/2018
659068

Return
Creating a Web VI in a project results in a broken run arrow on the Web VI

Workaround: When a Web VI is created, it is targeted to the "This Computer" target. Web VIs must exist in a Web Application (application targeted to a Web Server target) in order to run. Create a Web Server target in SystemDesigner, then create an application on the target and add your Web VI to the application.

Reported Version: 2.0    Resolved Version: N/A    Added: 03/21/2018
