Lookup relationship field in Ideas Object behaves differently
|Knowledge Article Number||000198649|
|Description||When a look up field is added in Idea Page (example - a look up field for account), then when an idea is created from the account, it redirects the user to Idea zone and after that the account cannot be seen added to the Idea. It needs to be re-added even though it is being added from the Account related list.
|Resolution||This is working as designed.
Ideas are built on top of Visualforce. This is different from rest of the entities that use a standard entity UI framework which is capable of handling redirects from related lists. The Ideas page doesn't handle those redirects because, it doesn't know in advance, the various parameters that may be received and hence the system would not know how to link it up with the custom fields.
