In developer mode, I've accidently set a condition on show hide object which is incorrect.
I can't get the object to show since I can't remember the erroneous condition.
How can I make all objects on a sheet appear (disregard the conditional show).
Just to complete the answer
if your document has data reduction, the option 'Document Objects' will appear only if you are a ADMIN if you are a USER at the Section Access this option won't be avaliable for you : )
Thanks Daniel for asking this question. Same problem arised with me. Object viewer is pretty good.
As all answered, it fixed my problem as well. Now I am able to update the settings from settings>sheet properties> object tab and select the object and update the properties.
Nice and easy explanation. Thanks all.
