------------------------------------------
Summary: Select component fails validation due to type mismatch
when using model generated from String
Key: TAP5-2184
URL: https://issues.apache.org/jira/browse/TAP5-2184
Project: Tapestry 5
Issue Type: Bug
Components: tapestry-core
Affects Versions: 5.4
Reporter: Howard M. Lewis Ship
A recent change to the Select component enables, by default, the validation of
a submitted value to a Select against its SelectModel.
This works fine in most cases ... however, when the SelectModel is created from
a String, the values are also Strings even if the property edited by the Select
is a non-String type (relying, again, on TypeCoercer to convert). This causes
a failure in the typical case where the string is a list of number, say
"1,5,10"; the provided SelectModel provides the values as strings, e.g., "10",
which does match against even a valid submitted value, since the ValueEncoder
will have converted the value to a number before the search.
