about update file form!

[laiqinyi]

 well, I wanne insert a data-item with some files to update, and record the 
filePath in the data-item.
the form is like that:
 
(following is a form)
field1: title
field2: content
field3: update files path --  update button --(here wanne a update form)
 
submit button
 
 
 well I find wicket not support 'two' forms in one page. It throws some Rending 
Exception.
How to deal this problem?
 
Maybe, use two page, one update form, one data-item form, and after update 
files, save the file path in the session. it's that OK?

how to create the component dynamic?

[laiqinyi]

 Well, I wanne build a Survey-System!
Now there're some Questions in the Survey-System, and will default some 
answer-item for user to choice!
following is the example of Question
1,It's the weather good today?(A.B.C. would be radio)
  A.yes, Sunny
  B.no, Rainy
  C.so so
I think all the component shall be created at run time! but some question has 5 
items some has 3 items,
some is a TextField which filled by user, some is CheckBox or Radio.
How to do with this?

when the value is null, wanne judge "null" adn translate the type to string

[laiqinyi]

Hi,
I have a entity POJO contain some property, the Type is Data, Character, 
Interger,String
I wanne to display then in  Tag,


When the String Type is null, the wicket is display ok.
but the Date Type, Character Type is null, it cause some NullPoint Error in the 
browser.

so that, I write a Translate Class like this:
public class TransUtil {   
public static String char2String(Character c) {
if(c==null){
return "Yes";
}
if (c.equals('1')) {
return "Yes";
} else {
return "No";
}
}
public static String int2String(Integer i){
if(i==null){
return "defaultMsgID_UnDefault";
}

return i.toString();
}

public static String date2String(Date date){
if(date==null){
return "defaultMsgID_UnDefault";
}

return date.toString();
}
}

I don't think is a pretty solution, and I wanne know others how to solve this 
problem?

It is there any Component not translate the HTML tag, and display the right format

[laiqinyi]

Hi  All,
 
now, I have integrated a wyswyg Editor with Wicket,and I save a lot of HTML tag 
into DataBase.
The problem is, HTML tag could not show correct form, but display the 
ESC(transferred) tag
for example:

in the database there is :
rr

in the html source code there is:
rr

and It can see rr in the browser,lost format

So, It is there any Component not translate the HTML tag, and display the right 
format

BestRegards,
