> The expression #{tableColumnForm.inputType.visualDefinition} should be evaluated \
> only if inputType is of type "label" (then #{tableColumnForm.inputTypeName == \
> 'label'}). AliasBean tries to save state of all its children without regard if they \
> are (was) rendered or not. In my case, if #{tableColumnForm.inputTypeName == \
> 'label'} is false, then #{tableColumnForm.inputType} doesn't contain \
> "visualDefinition" property (because it contains reference to another object in \
> that moment) and that causes an exception. If I replace x:aliasBean tag to eg. \
> <h:outputText value="#{tableColumnForm.inputType.visualDefinition.fontFace}" /> \
> then it doesn't throw the exception although #{tableColumnForm.inputType} doesn't \
> contain "visualDefinition" property. So, in short: aliasBean should not save state \
> of its children when its parent is not rednered (because its children could contain \
> references to for example not existing properties). I hope my explanation is enough \
> clear. If not, please notify me (in the comment). Thanks in advance for your effort
