If subform is not default, then it will not be processed after applyRequestValues phase. However, it is how I understand it's behavior. I too find subform description a little unclear.
As for you example: 1. if you click "-->" then event's source subform will be processed (selectOneChoice is validated) and all parent's form input components (if any). "project name" subform is ignored. In general - all other subforms (weather they are default or not) will be ignored. 2. if you click "Save" button, then all form's components will be processed, and all it's default subforms (both inputs will be validated for "required" constraint). Strange, that it don't work for you. I tested it on Trinidad 1.0.2/MyFaces 1.1.5 and everything was working as you asked. > Anybody? > Help? > Please? > > > > > > Hi. > You can try something like that (removed all EL's to test it locally): > > <tr:form defaultCommand="saveButton"> > <tr:panelFormLayout> > > <tr:subform default="true"> > <tr:panelLabelAndMessage for="projectLeadSelect" > styleClass="inputLabel_10" label="Project Lead" > showRequired="true" > > <tr:panelHorizontalLayout> > <tr:selectOneChoice id="projectLeadSelect" > simple="true" > required="true" > unselectedLabel="" > > </tr:selectOneChoice> > <tr:commandLink action="employee" text="-->" /> > </tr:panelHorizontalLayout> > </tr:panelLabelAndMessage> > </tr:subform> > <tr:subform default="true"> > <tr:inputText label="Project Name " required="true" /> > </tr:subform> > > <tr:commandButton id="saveButton" text="Save" > action="saved" /> > </tr:panelFormLayout> > </tr:form> > > Note, that if selectOne's unselectedLabel will be other than empty > string and it will be the only option in select element, then > selectOneChoice will be validated only on server side. > Assume both inputs are empty.
