Summary	0012814: EVENT_BUG_CHANGE_STATUS_FORM and EVENT_UPDATE_BUG_DATA events undefined
Description	Hello, I am planning to implement a plug-in to MantisBT to do some modifications while changing bug status. Unfortunately I have problems right at the beginning. I found a documentation to develop a plug-in with information about events (http://docs.mantisbt.org/master/en/developers.pdf). I found event EVENT_BUG_CHANGE_STATUS_FORM and EVENT_UPDATE_BUG_DATA in the documentation which seem to fit my need. Unfortunately, when I try to hook them in my plug-in, it is said these events "have not yet been declared". I made some research of the source code and there is really no event signalization for such events. I want to ask, why are these events mentioned in the documentation but not signaled in the real application code. How can I hook my plug-in to modify bug data while updating? Should I update the core code to include custom event signalization? What about later updates of mantis core - I would lose my changes. Thanks for your answer and advice.

I looked for an event which can compare old and new bug data, but I used EVENT_UPDATE_BUG now and called bug_get() method to get the old bug data to compare with.

zrybola 2011-03-01 10:04 reporter ~0028331	Now I came across another situation. I need to add an input for a custom field to the form when changing status of a bug from specific status to another. I cannot set the custom field required on update, as it is required only for this specific status update. However, I don't want to "edit" the bug first to be able to change the status. I searched the source code of page bug_change_status_page.php for signaled events but there is only EVENT_BUGNOTE_ADD_FORM event signaled which is definitely not the one I need. I have another function hooked to EVENT_UPDATE_BUG to process the status change but this needs the custom field filled in. What should I do? How can I add an input for a custom field in the change status form? Do I need to edit the core code and add a new signal there? How can I upgrade Mantis to higher version with such changes made in core code? Thanks a lot for your suggestions.

cas 2011-03-01 10:19 reporter ~0028332	If you need an event, you can add one in the core code, make sure also to update events_inc.php (for defining the event) . Be aware that updates will take away these changes. If you use a plugin, you can define new events in the plugin but still need to adjust the core code to have the trigger placed.

zrybola 2011-03-01 10:21 reporter ~0028333	I was afraid of this. I will have to add an event and make some reminder to add the event again after any Mantis core update. Thanks.

zrybola 2013-08-06 04:35 reporter ~0037624	The problem has been solved by editing the core code and adding several new events hooked in a plugin. I suggest closing this ticket. Thank you, cas, for your advice.

dregad 2013-08-06 16:44 developer ~0037639	Assuming you eventually want your plugin to become public (mantisbt-plugins github repo), I suggest you post a git patch of core changes you made, so we can evaluate whether it can be included in a future release
