I have 3 tabs that contain web resources. The web resources do not exist under the first tab. The web resources will only load if I click on the tab.

Is this standard with the UCI or is this a bug.

I did find this article stating that you have to click on the tab in order to load the web resource or move all you web resources under the first tab.

I hope this is a bug and MS is fixing the issue.

Yes, this is by design today. community.dynamics.com/.../xrm-page-getcontrol-webresource-getobject-contentwindow-document-error-in-unified-interface

Use something like this to skip the code execution.

var iframeObject = formContext.getControl('WebResource_Tags').getObject();

if (iframeObject == null)

return;

Hello,

Indeed, this is by design to optimize performances.

Have you referred to that article?

https://docs.microsoft.com/en-us/powerapps/maker/model-driven-apps/optimize-form-performance#form-scripts

Use collapsed tabs to defer loading web resources
When web resources or IFRAMES are included in sections inside a collapsed tab they will not be loaded if the tab is collapsed. They will be loaded when the tab is expanded. When the tab state changes the TabStateChange event occurs. Any code that is required to support web resources or IFRAMEs within collapsed tabs can use event handlers for the TabStateChange event and reduce code that might otherwise have to occur in the OnLoad event.
