Lumira Extension Thumbnail Error

[Former Member]

Anyone run into this particular error? Noticed when we add our extension into Lumira and start adding data it throws this error.

Hi Ryan - I for sure am not a developer, but I did find something in the release restrictions for 1.25 Lumira - see http://help.sap.com/businessobject/product_guides/vi01/en/lum_125_vp_en.pdf

Page 7:

"Thumbnail view may not correctly show an extension if it uses DIV as root container This is a known limitation in SAP Lumira that will be fixed in a future release.

Thumbnail view may not correctly show an extension if it uses external CSS files This is a known limitation in SAP Lumira that will be fixed in a future release"

Could this be related to your issue?

Thanks Tammy,

Not loading any external CSS files since it is 100% JS driven, but we are loading into a DIV container, so that looks like the problem. Digging deeper if this is a root cause for some other issues I am experiencing if it is a simple isolated known issue.

Will share my findings on this thread. Cheers!

To close the loop on this one.. The thumbnail error was un-related to other issues I was experiencing. It was in there plain as day in known issues but not communicated back to me. All issues resolved and component is all done . Will share the experiences and lessons learned on blog post shortly.
