I've seen threads on this issue and haven't found a good easy solution. Somewhere along the line "Transparent" becomes invalid. I click background color... it shows options and I select "No Color" which types "Transparent". And then I get the warning when the report renders in preview. I saw in another thread to try using the word "Nothing" - which I get an immediate invalid color error.
It all works fine in production... this is more of an irritation with all the warnings.
I'm not doing an expression... just want that text box with no color.
I'm sure there's something easy I'm missing. Then again - with the other bugs I've run across - the worst offender being subreports won't render in preview - you have to deploy them! Maybe it's not so easy. Thank you!
