General OMI web client limitations

The following list summarizes the major general limitations in the current release of the OMI web client.

• Multi-Galaxy configurations are not supported with this version of the web client.

• Secured and verified writes are not supported in this version of the web client.

• You cannot customize the web client URL used to call a specific ViewApp directly.

• You cannot customize the graphics used to indicate ViewApps on the initial OMI web client page.

• Embedded .NET controls will not render correctly on non-Windows devices. Only Windows devices support rendering of .NET controls.

• Security certificates with Public Domain Names are currently not supported by the OMI web client.

• History playback is not supported in this version of the web client.

• The web client cannot show multiple screens at once. If a ViewApp uses multiple screens, you can switch between screens in the web client window. See ViewApp behavior in the web client for instructions.

• You cannot preview an OMI ViewApp based on how it will look in the web client. The Preview button on the ViewApp editor shows a desktop client preview only.

• You cannot generate a URL for a page displayed in the web client and then embed that URL in another product to access the content. This is possible in the InTouch web client, but not in the OMI web client.

• By default, you cannot place the web client window in an iFrame, as doing so could make the web client vulnerable to a "clickjacking" attack. If you need to put the web client in an iFrame, see Placing the Web Client in an iFrame.

• In very complex graphics with a large number (thousands) of references, some references may take a very long time to resolve when compared to the OMI desktop client.

• If a user increases the size of a layout during runtime to exceed the defined size of the panes in the layout, the panes will expand to fill the layout, even if they are set to fixed size.

• If you have upgraded the GR node from SP 2020 R2 SP1 to SP 2023 R2 SP1, but have not yet upgraded remote run-time nodes, communication between the GR node and run-time nodes will be lost until the remote nodes are upgraded. Therefore, ViewApp run-time data will not be updated on non-upgraded remote nodes until the remote nodes are upgraded to SP 2023 R2 SP1.

• This version of the OMI web client does not support InTouch-specific references. As a result, the web client will not display run-time data from InTouch applications.

  Important! Several graphics in the Visualization folder incorporate elements or settings that are not supported by the OMI web client. Before using a system graphic in a ViewApp that will be used with the web client, make sure that it will display properly on all devices where it may be accessed.

When loading a graphic in the web client, unsupported features are logged as warnings in the Logger. A generated report will include the warning path.
