[jira] Updated: (TAPESTRY-1598) Tapestry should not require
explicit value encoders (via the encoder parameter) where it can
automatically coerce the value between string and the appropriate
server-side type
[ https://issues.apache.org/jira/browse/TAPESTRY-1598?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Howard M. Lewis Ship updated TAPESTRY-1598:
-------------------------------------------
Summary: Tapestry should not require explicit value encoders (via the encoder parameter) where it can automatically coerce the value between string and the appropriate server-side type (was: Trivial SelectModels (e.g. Lists of Integer objects) now require a ValueEncoder whereas before they "just worked".)

> Key: TAPESTRY-1598
> URL: https://issues.apache.org/jira/browse/TAPESTRY-1598
> Project: Tapestry
> Issue Type: Bug
> Components: tapestry-core
> Affects Versions: 5.0.5
> Reporter: Nick Westgate
> Assignee: Howard M. Lewis Ship
> Priority: Minor
>
> (This could be considered an enhancement except that it worked in a previous snapshot.)
> Summary says it all but here's a simple example:
> html:
> <select t:type="select" t:value="someIntegerProperty" t:model="selectModelList"></select>
> java:
> public List getSelectModelList() // note list is currently broken as per TAPESTRY-1597
> {
> List<Integer> model = new ArrayList<Integer>();
> model.add(new Integer(1));
> model.add(new Integer(2));
> return model;
> }
> Now results in the following exception:
> org.apache.tapestry.ioc.internal.util.TapestryException
> No adapter from type java.lang.Integer to type org.apache.tapestry.services.ValueEncoderFactory is available (registered types are java.lang.Enum, java.lang.String).
> Defining ValueEncoders for all the simple wrapper types used in domain objects defeats the purpose of all the smart type conversion Tapestry does elsewhere.
> Cheers,
> Nick.
