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

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
681183

Return
In some cases code placed outside of a loop with no data dependencies on the loop will not run until the loop has stopped

Reported Version: 2.0    Resolved Version: N/A    Added: 03/21/2018
691224

Return
Case structures are unable to recognize " as a selector
When a string selector is used, creating a case for the " character results in the default case running rather than the " case

Workaround: Use an Equals primitive to check for the quote character instead of or in addition to the case structure

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