I believe you have the setHardwareType method, which will be called after the valueChangeListener method causes values to be overwritten to null or previous values. This sequence is part of jsf life cycle. You can put a break point/println's in the hardwareTypeChanged and setHardwareType you will know the sequence. One way to avoid this overwritting is have empty setHardwareType method ( do nothing in that) , have getHardwareType to read the values and use valueChangeListener method (hardwareTypeChanged) to update the HardwareType. You do not need immediate="true" / facesContext.renderResponse().
hope that helps. -Sreeni. -----Original Message----- From: Bruno Aranda [mailto:[EMAIL PROTECTED] Sent: Tuesday, June 13, 2006 1:37 PM To: MyFaces Discussion Subject: Re: Conditionally rendered fields not retaing values Does it work if you remove the immediate="true" attribute from the selectOneRadio (see this docs to see if you really need it [1]), and remove the facesContext.renderResponse() line (not needed).
