Ok, I followed your lead and tried both 1. repaired spelling of integer. Still
failed 2. Tried Jesse's version. That failed too
@Persist
@InitialValue('ognl:2')
public abstract int getTableSize();
public abstract void setTableSize(int tableSize); The select comes up with
initial selected '1' highlighted blue I navigate and select '4' Post occurs
select comes up with initial selected '1' Then it highlights to blue Cannot
get this binding to stick. I attached the sources if that helps... might it be
this configuration of RenderBlock and Block...
Hoping to resume.. thanks for your time.Best regards
Ken in nashua
