display different fields depending on issue type

[Nariman Riahi]

I need to display create issue screen with different fields depending on the selected issue type.

For example for Bug I need to show a certain field.

For Task display a different field.

I have started reading about it and it seems just so complicated and I want to make sure I don's mess it up. I would appreciate any help I can get.

It looks like there are several ways to do this also. Anyone has done this?

Thanks

You need to define an issue type screen schem. This lets you define one screen Scheme per issue type. The issue type screen scheme is assgned to yourvproject. A screen scheme in turn lets you define one screen per create/view/edit mode. Here is the procedure ( bottom up) If you have 3 issue types, create one screen scheme for each issue type. I recommend to use something like issuetype.screenscheme as the name. Also create 3 screens for the different issue types. In the screen scheme map the create view to the create screen you have created. After you have done this you create an issue type screen scheme and map the issue types to the screen schemes. Then assign the issue type screen schemevto thevproject

Thanks Dieter. I did everything as you said. One issue remains.

I have now 3 screens that are empty (since I did not configure the fields yet). But when I try to create an issue with either of these issue types I get the default screen (not the empty screen that I was expecting)

Check if each of the three screens belongs to a screen scheme which in turn belongs to an issue type screen scheme which in turn must be assigned to the project.

Dieter, thank you do much for your help. After reading up more and more about this. Do I really need seperate screens for each of these issue types? Can I not achieve this sung the default screen?

[Dieter]

yes, there is a way using one screen only. In this case you would have to define a field configuration scheme with one field configuration peer issue type. Each field configuration would disable the fields that you do not need.

This was posted by Matt Doar and is the only thing that clarified this question for me! 

The key part is that you want to create one ITSS and then configure each project to use that same ITSS. 

In that ITSS you have a mapping from the issue type X to a screen scheme usually named "X Screen Scheme". That screen scheme then has a mapping to one, two or three screens for creating, editing and viewing issues of type X.

There are not many ways to do it. May be two ways.

1. Adjust the settings in "Issue Type Screen Scheme"

2. Or use the same screen scheme, but customize the context of the custom fields to indicate to which issue-types they are valid.

Let me add more detail to my request.

I need to create 3 new issue types. DONE

For each of the new issue types I need a few custom fields added to the create issue screen.(not sure what the best way is)
