Frederic Daoud commented on STS-300:
------------------------------------
Agree with Kai - this would add too much complexity to the tag.
Anyone else care to comment on this issue so that we can decide whether to A)
look into implementing this feature, or B) close the issue as won't implement?
> Filtering for options-enumeration/options-collection
> ----------------------------------------------------
>
> Key: STS-300
> URL: http://www.stripesframework.org/jira/browse/STS-300
> Project: Stripes
> Issue Type: New Feature
> Components: Tag Library
> Affects Versions: Release 1.4.1
> Reporter: Andy
>
> Currently the options-enumeration and options-collection tags render all
> values in the enum or collection.
> They will be more useful if filtering criteria can be specified when not all
> values should be rendered.
> package xxx.enums;
> public enum MyNumber { ONE, TWO, THREE, FOUR, FIVE, SIX, SEVEN;
> public boolean getIsPrime() { return this==TWO || this==THREE || this==FIVE
> || this==SEVEN; }
> public boolean getIsEven() { return (ordinal() % 2) == 1; }
> }
> <stripes:options-enumeration enum="xxx.enums.MyNumber"/>
> (renders all seven options)
> <stripes:options-enumeration enum="xxx.enums.MyNumber" where="isPrime"/>
> (renders only TWO, THREE, FIVE, SEVEN)
> <stripes:options-enumeration enum="xxx.enums.MyNumber" where="isEven"/>
> (renders only TWO, FOUR, SIX)
> If the proposed where= attribute supports some kind of expression language
> (EL?), it will be much more flexible:
> <stripes:options-enumeration enum="xxx.enums.MyNumber" where="isPrime &&
> !isEven"/>
> (renders only THREE, FIVE, SEVEN)
> For symmetry, the options-collection tag should likewise take a where=
> attribute.
> A typical use would be, where="theCurrentUserCanSeeThisOption" :)
