Hello Volker, thanks for the response. Yes I target the panel. I use now
actionListener and return null as return value. I also preset the value
of string1 so that the value is always already initialized. But
nervertheless the string2 is set to the new value (I debug that) but
after rendering the tx:in box is still empty. Maybe you can take a look
to the latest version of my test page and controller.
Best regards Michael

Hi Michael,
for actions used in partial rendering you should always return null!
I the action returns a string than a full reload is made!
I suggest using actionListener for partial actions.
When rendering partially only the requested subview (plus the action
component if outside) is processed on the server.
In your example you request reload of box2, which means the content of
box2 is processed and stored in the model.
In the action string2 is set to string1 but string1 was not processed
so it is still null here.
Have you in helmuts example really changed the value of
renderedPartially to the suggested panel arround both boxes?

2010/4/12 <[email protected]>:
Hello,
I'm trying to execute an action and partial rendering the result in an
<tx:in> field. The tx:button which calls the action and the tx:in elements
are in different forms. For some reasons after the new value is set to the
underlaying value of the tx:in field the setter of this value is called
from somewhere and overwrites the new value with an empty string. But I
want to have the value I set with my action1 method in the field instead
an empty string. Can some one tell me what I'm doing wrong?
Thanks a lot Michael
