RE: [Springframework-developer] Using PropertyEditors in JSPs

<quote>That sounds interesting, and it should be pretty easy to
integrate. But for the sake of getting 0.9.1 out ASAP, I suggest to hold
it back for after the release, just like the Tiles integration. I guess
we will release a 0.9.2 follow-up at end of August anyway, all that
stuff should fit in there in polished and tested versions.</quote>

Totally agree, I'll maintain in my local tree and test it a bit
further...

<quote>BTW, I really like the extensive Javadoc that you added to some
of the web controller classes, especially the explanations of the
workflows! Very, very welcome :-)</quote>

No problem, probably I'll have a chance to do some more tomorrow. After
tomorrow I'm on a holiday until the 13th by the way...

Subject: [Springframework-developer] Using PropertyEditors in JSPs


Everyone,=20
I've made an addition to the BindStatus and BindTag and added a
TransformTag (the name is still open for discussion) I wanted to discuss
with you before adding it.
When using <spring:bind>, a BindStatus object is instantiated for the
path (on the command class) I'm setting in the tag. Also, any
PropertyEditors that are associated to that field or type of property
are consulted to get the appropriate String representation for the
property. However, right now it's not possible to also retrieve String
representations for any referenceData I've bound in the requestContext.
Consider the following:=20
I want to add a user and the user has a property called language
(preferred language, with associated getLocale() and setLocale()
methods)=20
Using a formcontroller I've returned the formBackingObject as well as
some referenceData (in this case, a list of Locale objects from which
the user wants to choose)=20
To be able to let the user choose one of the locale objects and let the
framework set the right locale using the associated LocaleEditor, I need
to be able to make consult the LocaleEditor for the locales in the list
as well=20

I thought of the following to make this work. Everything enclosed by
<spring:bind>-tags applies to a certain path of the command object and
therefore (if applicable) an associated PropertyEditor. So anything
enclosed by those tags could be rendered using that specific
PropertyEditor as well.
The attached example shows the final JSP used to implement the above
usecase.=20
Modification that need to be made to add this functionality are the
following:=20
getCustomerEditor()-method to BindTag and Errors interface (and
corresponding implementations in BindException and EscapedErrors
(returning the appropriate editor or null if not applicable or not
found)=20
Addition of transform-tag to be used inside bindtag=20

The only thing I'm not sure about is the first modification=85=20
Any comments, objections or remarks about the implementation?=20
