Hello Thiago H de Paula Figueiredo-2 and All Tapestry Developers, If you remember you helped me in the problem of persisting the value of select component in action request, it is working correctly now.
I have some thing different now. When I save new value in database which is actually shown in this select component, after saving and rendering the page the select component shows the new value. But when I select this new value to perform action it doesn't persist in action request it is received as null while other previous values of this select component never received null on action after saving new value. Only new value received null in action so it does not persists on page after action request. Can anyone tell why this happening? Am I wrong somewhere? Any help is appreciated... Thanks in advance...
