Hmm. Maybe I misunderstood you. When you enter a value into a field in the page, tapestry will call to the getter for that variable when the page render, and the setter of the variable (with you entered value) when you submit the form of which the (I assume) TextField is a part, like;
<div jwcid="@TextField" value="ognl:myvalue"/> .. public abstract void setMyvalue(String v); public abstract String getMyvalue(); Then, the next time you enter something in the field and submit, the old value will be overwritten and tapestry will count on you to have saved it. Again, apologies if the problem is something else altogether. Cheers, PS On 5/29/06, Stephane Decleire <[EMAIL PROTECTED]> wrote:
