<p:selectOneMenu id="tasktypeval" value="#{buildConfigureBB.taskType}">
<p:ajax listener="#{buildConfigureBB.on_projectIdchange}" update="Projecttasklable,CmdTypebuild,CmdTypeconfig,comment2val" process="@this"/>
<!-- <f:selectItem itemLabel="Baseline" itemValue="Baseline" /> -->
<f:selectItem itemLabel="Build" itemValue="Build" />
