Struts: HTTP Request Parameter overwrites ActionForm Field ?

[michel777]

Dear developers,

I need help to the following problem. Scenario:

User edits the Field "comment" on the HTML page (.e.g. "hello"). This field corresponds with ActionForm property comment. I set the the ActionForm.comment null in the Action class(the HTTPServletRequest Parameter comment remains "hello" there is no methode to change it). After that will the page displayed again, but the field comment is no more visible for the user (with javascript is disabled). User sends the
page and in the (same) ActionForm is the comment property nit null, but
"hello".

Could anybody advise me ?

Warm regards,

Laszlo
