Peter Klügl commented on UIMA-2463:
-----------------------------------
I committed the proposed changes that are probably not the best way to solve
the problem but should do the trick. Jörn, are the changes ok?
> Improve default annotation style assignment of CAS Editor
> ----------------------------------------------------------
>
> Key: UIMA-2463
> URL: https://issues.apache.org/jira/browse/UIMA-2463
> Project: UIMA
> Issue Type: Bug
> Components: CasEditor
> Affects Versions: 2.4.1SDK
> Reporter: Peter Klügl
> Assignee: Peter Klügl
> Priority: Minor
> Fix For: 2.4.1SDK
>
>
> DefaultColors.assignColors() assigns style background with somewhat random
> but different bright colors to all types. This method is called when is type
> system is not known yet.
> AnnotationStyle.getAnnotationStyleFromStore() tries to read to stored style.
> If there is no information, then the style is set underlined red.
> The situation in my use case is the following: I create a script with some
> type definitions resulting in a type system. I write some rules and test the
> result by taking a look at the xmi with the CAS Editor. Here, the first
> method is applied, because the type system is new. Then I write additional
> rules and add some other types. If I now review the result, the new types in
> the known types system are all set to red/underlined, because if the second
> method. Thus, it's harder to distinguish them.
> A solution is the assignment of a random bright background color as default
> in AnnotationStyle.getAnnotationStyleFromStore(). However, the colors should
> not change randomly if the type system changes. So after a style is assigned,
> this style should be stored inside the configuration, instead of repeating
> the process the next time the CAS is loaded. If the process is repeated and a
> change occurs to the type system, then the style assigning code might choose
> a different color.
