Hello,
In my case there is a course, and several documents related to course which I want to attach. The document have name, date and keywords. After I write them, I use rich:upload to temporaliy keep tthe document to be attached. When I finish uploading it, I want a blank interface to enter data for the next document. I use <a4j:support event="onuploadcomplete" reRender="panel, panel1" /><a4j:support event="onuploadcomplete" reRender="panel, panel1" /> to get a blank text and date box. this helps me to clear the data table which I keep the key words. but h:inputText and rich:calendar areas are always there with previous values. Whatever I do they are always there. I even tried ajax commandButton to rerender those fields. But they are never blank.
The other problem is I want date in dd.MM.yyyy format. When I save them there is hour and minutes. I do not want to see them, why they are there? The worse, in the data table I see temporaliy kept document, date is in a very different format (sometimes long date sometimes it is like 09 jun 2009). Why I can not see in my datatable in the way I want it? My code is below. I'd appreciate a lot If you help me. Thanks... (I use RF 3.3.1 with spring and hibernate. Sorry for the code junk:( )
