BeanValidator validation groups are overwritten with PSS
--------------------------------------------------------
Key: MYFACES-2528
URL: https://issues.apache.org/jira/browse/MYFACES-2528
Project: MyFaces Core
Issue Type: Bug
Components: JSR-314
Affects Versions: 2.0.0-beta
Reporter: Michael Kurz
Setting the validation groups of a bean validator like <f:validateBean
validationGroups="#{bean.groups}"/> is not always working correctly with PSS.
Property bean.groups returns null or the class name of a validation group in my
example based on the value of a boolean checkbox:
<h:selectBooleanCheckbox value="#{bean.prop1}"
valueChangeListener="#{bean.prop1Changed}"
immediate="true" onclick="this.form.submit()"/>
<h:inputText value="#{bean.prop2}" rendered="#{bean.prop1}">
<f:validateBean validationGroups="#{bean.groups}"/>
</h:inputText>
If I check the boolean checkbox the form is submitted and rendered again with
the additional input field. The problem now is that the validation groups are
set correctly on building the view during the second traversal of the lifecycle
before restoring the state. But on restoring the validator this value is
overwritten with the old value from the state and my validation group is gone
again.
As the BeanValidator is a PartialStateHolder this can be avoided by only saving
and restoring the state if the initial state was not marked.
