[Grok-dev] Indexes not updated on object modification

[Sebastian Ware]

You have to call 

  grok.notify(grok.ObjectModifiedEvent(the_modified_object))

for indexes to be updated if you update properties manually. This is done automatically in when you do

  self.applyData(self.context, **data)

in forms. This is easy to forget and I do all the time... but it gives nice control over when the reindexing of the object is performed. It also exposes a useful event to listen to if you have other objects that need to be updated on modifications (you would need to fire grok.ObjectModifiedEvent events in those event listeners too if the change affects the indexing of those objects).
