>
> Key: RF-10170
> URL: https://issues.jboss.org/browse/RF-10170
> Project: RichFaces
> Issue Type: Enhancement
> Security Level: Public(Everyone can see)
> Components: compatibility
> Affects Versions: 4.Future
> Environment: RichFaces 4 svn rev. 20933
> Reporter: Martin Kočí
> Assignee: Nick Belaevski
> Fix For: 4.0.0.CR1

>
> example (#{bean.propertyNull} resolves to null):
> <h:inputText value="#{bean.propertyNull.zeitangabe}" /> outputs a input field
> <r:calendar value="#{bean.propertyNull.zeitangabe}" /> throws
> value="#{bean.propertyNull.zeitangabe}": Target Unreachable, 'propertyNull'
> returned null
> Problem is in org.richfaces.component.util.SelectUtils.findConverter: method
> tries to locate a Converter even if informations for this are "uknown".
> Simple solution can be: find converter only for ValueExpression which leads
> to not null value, because if no value for "value" ValueExpression :), then
> no conversion getAsString is necessary (at least is is true if spec does not
> mandates conversion for null value).
