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
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
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
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.
