Michael Allman commented on PIVOT-573:
--------------------------------------
Hmmm... this is really about adding support for evaluating script expressions,
not adding support for static factory methods. The latter is just a tiny
special case for this and was the motivation for the addition of this feature.
You might have an expression that manipulates a string, for example. Or
computes some arithmetic.
Anyway, I still don't see what the big deal is. This adds a lot of power at a
small price. Ah well.
> Execute script expressions in WTKX component attributes

> Key: PIVOT-573
> URL: https://issues.apache.org/jira/browse/PIVOT-573
> Project: Pivot
> Issue Type: New Feature
> Components: wtk-wtkx
> Affects Versions: 1.5
> Environment: Using patched Pivot 1.5
> Reporter: Michael Allman
> Attachments: script_expressions_in_attributes.patch
>
>
> The attached patch allows users to put arbitrary script expressions in wtkx
> component attributes. This provides a superset of existing functionality,
> which allows the user to reference an object by its wtkx:id.
> For example, I have a Java class ms.allman.pivot.Validators with a static
> method getZipCodeValidator() that returns a Validator. Then the following
> WTKX fragment sets a zip code validator on the given TextInput:
> <TextInput
> validator="$Packages.ms.allman.pivot.Validators.getZipCodeValidator()"/>
> (This example assumes the use of the JavaScript engine for scripting.)
