This is because Tableau cannot render the contents inside these web page objects. It is essentially just a container and Tableau has no knowledge of what is inside it. Hope this helps!
It leads me to the next obvious question...
I have an action that brings up an image (jpg) of a feature when hovering over a mark on plan which is a background image. I then need to print the dashboard with plan and the photo of the feature.
Does anyone have an idea how I can print the dashboard and image?
Any new insights on this matter ?
perhaps with tableau 8
i have the same issue and would like to print/export te result
my dashboard contains graphs/tabels and some external images (weather related) which i would like to save
i could perhaps use a external screencapture program but thats not the optimal solution i am hoping to get.
