----------------------------------------
From IRC:
(09:51:34 PM) stuartdouglas: really EntityConverter can be replaced with a generic
conversation scoped convertre
(09:52:13 PM) stuartdouglas: basically you have a conversation scoped components with a
map<String, Object>
(09:52:29 PM) stuartdouglas: when you convert to a String you generate a arbitrary string
id and store it
(09:52:39 PM) stuartdouglas: to convert back you just do a map lookup
(09:52:52 PM) stuartdouglas: so you can convert anything as long as you have a
conversation active
(09:57:40 PM) bleathem: one could use the view scope, no?
(09:57:48 PM) bleathem: you always post back to the same page
(09:57:49 PM) stuartdouglas: yes, any long lived scope would work
ObjectConverter and EntityConverter
-----------------------------------
Key: SEAMFACES-28
URL: https://issues.jboss.org/browse/SEAMFACES-28
Project: Seam Faces
Issue Type: Feature Request
Components: Transactions & Persistence, Validation & Conversion
Reporter: Pete Muir
Assignee: Jason Porter
Priority: Critical
Fix For: 3.1.0.Tracking
Given
class Foo {
Bar bar;
// Getters and setters
List<Bar> bars;
// Getters and setters
}
<h:selectOneMenu value="#{foo.bar}" >
<f:selectItems value="#{foo.bars}" var="bar"
itemLabel="#{bar.label}" itemValue="#{bar}" />
<s:convertEntity /> || <s:convertObject />
</h:selectOneMenu>
I want to be able to have my setter/getter reference an object and not write the
boilerplate for converting to/from a string.
I also want to reference a managed entity, and have that managed entity set back into the
setter so I can see the changes updated in the database with no boilerplate, and avoid
LIEs.
