Improve Converter finding if EL expression is semi-resolvable
-------------------------------------------------------------
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: Future_4.X
Environment: RichFaces 4 svn rev. 20933
Reporter: Martin Kočí
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).
