This is not the expected result. When changing a product, you get a second page that allows you to change the component, version, milestone, release, and (if applicable) group privileges.

Bugzilla is designed to work without Javascript on, so having a separate page is required. Additionally, this enforces users who change the product a bug is assigned against to actively think about these values.

Comment 2 Michal Privoznik 2012-05-23 07:10:27 UTC

Well, if this is the case, and I change the product in the first place, then why the component list gets read from the new product I've chosen and not the old one?

Comment 3 Michal Privoznik 2012-05-23 08:27:11 UTC

Moreover, if have this separate page anyway, why not keep those two fields (product + component) in sync? Usage scenario is this: I've had a bug for libvirt (P: Virtualization tools, C: libvirt) but it turned out to be a libvirt-glib bug. However, there's no such component under Virtualization tools product. So I had to search for product containing the libvirt-glib component.

If I've changed the Product firstly then component list got refrest with respect to product I've chosen; which is cool. So I've chosen a product A and found out libvirt-glib is not there. So I've chosen the product B, C, ..

Even though there is a separate page for confirmation and make users stop & think, I still think this is a reasonable request.

Technically, that is a bug (the AJAXy part of the page is a Red Hat customisation).

Getting a list of components for the Fedora product via AJAX is very client side CPU intensive (see bug 823309 for an example), so having it on a separate page is the correct thing (IMO).

Comment 5 Michal Privoznik 2012-05-23 13:16:04 UTC

I think we both agree that separate page is the right thing.

What I am reporting is however something different. From my understanding the bug 823309 you are referring to is fixed now. And yeah, I can confirm it is eating some CPU but not so much (it takes ~5 secs to get list of Fedora components). What am I asking for is a way for matching component against Product. I'd like to switch bug to another component which however is under different product. But I don't know which one. Or do you suggest any other way of finding that out? Of course, I still would be redirected to the separate page.

Moreover, the feature I am requesting we already have: when you're doing 'Advanced search'. Selecting any item in a list will refresh subsequent list.

https://bugzilla.redhat.com/describecomponents.cgi?product=Bugzilla (for example) is the correct place to get this information. You can get this page by clicking on the Browse link, selecting a component, and then click on the 'Show full component descriptions for this product' link.
