A MetaAttribute has been created In MEGA Tool with a propertypage (so it shows in the instance under properties as a tab), but it does not show up in the properties tab via Advisor.
Where does MEGA handle the items that are populated in the Advisor Advance Search Tool under Properties tab?
The Advisor website contains built-in macros that retrieve the property pages of the objects. So, normally it should work.
have you tried to clear the cache + kill all the MEGA / Advisor processes?
if not, proceed with this way and you will get normally your customized MetaAttribute displayed on Advisor.
Unfortunately, this does not resolved the issue. The metaattribute (MA) was created a while ago. Cache is deleted once a week, and the new MA does not show up. You mentioned that mega has macros that handle this, could you point me towards those macros?
