RE: html:checkbox tag not setting its property value in Formbean

2002-03-12 Thread Krishnan 

Hi Larry,

Thanks for your suggestion.  I downloaded the nightly
build for struts (dated 3/11/02) and installed it in
my Tomcat 4.0.1 environment.  In My Jsp I have the
following logic:iterate tag

logic:iterate id=segmentElementRow
type=com.xxx.ui.action.SegmentElementSelectRow
name=addSegElementsToMethodForm
property=segElementSelections 
 tr
   td align=center
html:checkbox indexed=true 
name=segmentElementRow property=selected
value=true  /
/td
td align=center
bean:write name=segmentElementRow
property=elementNbr /
/td
td align=center
bean:write name=segmentElementRow
property=elementName /
/td
td align=center
bean:write name=segmentElementRow
property=baseTable /
/td
/tr
/logic:iterate

At loading the jsp compiler is complaining about no
getter method available for property indexed!.  Also,
the struts documentation for html:checkbox tag does
not talk about an attribute indexed for html:checkbox.
 Is this the right syntax ?.

 In you form bean:

   return fruits;
 }
 
 public void setFruits(ArrayList _frutis) {
   fruits = _fruits;
 }

 public void setFruits(int index, Fruit fruit) {
   fruits.set(index,fruit);
 }
 
 public void reset(ActionMapping mapping,

 javax.servlet.http.HttpServletRequest request){
   Fruit f = null;
   Iterator it = fruits.iterator();
   while it.hasNext() {
 f = (Fruit) it.next();
 f.setChecked(false);
   }
 }
 
 In your action class you would then create an array
 list of
 fruits and set them in your form bean.  After the
 form was
 submitted you would get the list back out and see
 which
 fruits were checked.
 
 The trick to make this work is that the id used with
 the iterate
 tag can not be random, it must exactly match the
 property in
 your form bean that you want to get set.
 
 I hope this helps.

  Hi
 
   In my Jsp form,  I have a check box that is part
 of a
  collection object.  This collection object is
 rendered
  through a bean. The collection (arrayList) itself
 has
  getter/setter in the form bean. When I select the
  checkbox on the form, the corresponding property
 value
  is not updated to true.  However, I saw that the
  request parameters had the property name for the
  checkbox with the value 'true'.  Are there other

  of getting the checkbox to set the property?.  Any
  examples would be appreciated.

Hi Krishnan,

See: http://jakarta.apache.org/struts/struts-html.html#checkbox

It has the indexed attribute:
indexed Valid only inside of logic:iterate tag. If yes then name 
of the html tag will be rendered as id[34].propertyName. Number 
in brackets will be generated for every iteration and taken from 
ancestor logic:iterate tag. [RT Expr]  

so I'm not sure why you would be getting an error message.  Also,
I just added it to a checkbox in one of my jsps and it compiled
okay for me.

I would like to see all of your error output.

Hi Krishnan,

So it's not a compile error.  Hmmm!  I haven't tried
my solution, so perhaps its still legal syntax, but
no longer supported.  Any comments from the news
group on this?

I know there is a multibox tag, but it doesn't have
an indexed attribute, so I'm not sure how one would
go about using it.  For grins, would you try replacing:

html:checkbox indexed=true 
name=segmentElementRow property=selected value=true
/

with
html:multibox name=segmentElementRow property=selected value=true /

and see if it works?  If so, please let me know.

RE: html:checkbox tag not setting its property value in Formbean

2002-03-11 Thread Maturo, Larry 

Hi Krishnan,

If you are using a nightly build you can probably use
the indexed attribute.  This would look something
like this:

In your jsp:
logic:iterate id=fruits name=nameOfYourFormBean property=fruits
html:checkbox indexed=true name=fruits property=checked/
bean:write name=fruits property=fruitName /
/logic:iterate

in class Fruit
public class Fruit {
private String fruitName = ;
private boolean checked = false;

public Fruit() {
super();
}

public String getFruitName() {
return fruitName;
}

public void setFruitName(String _fruitName) {
fruitName = _fruitName;
}

public boolean getChecked() {
return checked;
}

public void setChecked(boolean _checked){
checked = _checked;
}
}

In you form bean:

private ArrayList frutis = null;

public ArrayList getFruits() {
return fruits;
}

public void setFruits(ArrayList _frutis) {
fruits = _fruits;
}

public Fruit getFruits(int index) {
return (Fruit) fruits.get(index);
}

public void setFruits(int index, Fruit fruit) {
fruits.set(index,fruit);
}

public void reset(ActionMapping mapping,
javax.servlet.http.HttpServletRequest request){
Fruit f = null;
Iterator it = fruits.iterator();
while it.hasNext() {
  f = (Fruit) it.next();
  f.setChecked(false);
}
}

In your action class you would then create an array list of
fruits and set them in your form bean.  After the form was
submitted you would get the list back out and see which
fruits were checked.

The trick to make this work is that the id used with the iterate
tag can not be random, it must exactly match the property in
your form bean that you want to get set.

I hope this helps.

Hi Larry

Each element in the array list is a bean and the bean has a boolean property
for the checkbox.

 Hi Krishnan,

 Could you post more details.  Is the arraylist an
 arraylist of boolean, or an arraylist of some
 bean, which itself has a boolean property, or
 perhaps each entry in the arraylist is of a
 different type?

 Subject: html:checkbox tag not setting its property value in Formbean


 Hi

  In my Jsp form,  I have a check box that is part of a
 collection object.  This collection object is rendered
 through a bean. The collection (arrayList) itself has
 getter/setter in the form bean. When I select the
 checkbox on the form, the corresponding property value
 is not updated to true.  However, I saw that the
 request parameters had the property name for the
 checkbox with the value 'true'.  Are there other ways
 of getting the checkbox to set the property?.  Any
 examples would be appreciated.

 Thanks

 Krishnan
