Ok, i will try to expose one of my issues. <t:delegate t:to="activeMode"/>
<t:block id="processFormFields_1"> <----- Other fields----> <select t:id="subject" t:type="select" t:model="prop:subjectModel" t:value="prop:subject" t:mixins="ck/OnEvent" event="change" onCompleteCallback="updateSubsubjects"/> <----- Other fields----> </t:block> <t:block id="processFormFields_2"> <----- Other fields----> <select t:id="subject" t:type="select" t:model="prop:subjectModel" t:value="prop:subject" t:mixins="ck/OnEvent" event="change" onCompleteCallback="updateSubsubjects"/> <----- Other fields----> </t:block> The two blocks will never be displayed together, and i need the id of the component because i need to have component on the server side. I have solutionated my problem with a uggly solution. <t:delegate t:to="activeMode"/> <t:block id="processFormFields_1"> <----- Other fields----> <t:delegate t:to="subjectBlock"/> <----- Other fields----> </t:block> <t:block id="processFormFields_2"> <----- Other fields----> <t:delegate t:to="subjectBlock"/> <----- Other fields----> </t:block> <t:block id="subjectBlock"> <select t:id="subject" t:type="select" t:model="prop:subjectModel" t:value="prop:subject" t:mixins="ck/OnEvent" event="change" onCompleteCallback="updateSubsubjects"/> </t:block> This was one of the multiple times (and that i remember :D ) that i have faced this issue. I have worked with dynamic structure and liked that kind of behaviour but i know that dynamic structure my have some serious and dificult problems to solve. 2009/4/30 Christian Edward Gruber <christianedwardgru...@gmail.com> > I'm interested about this - can you elaborate what you mean by this?
