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. In that case on form submit
via button
only inputText will be marked as invalid, and only when it
will pass
validation - selectOneChoice will be processed
(server-side).
As for "required" mark placement, I guess one of
the options is to
implement your own renderer for panelFormLayout.
Hope it helps.

(Well, actually required
