html:select and html:options example?

[Stephan Niedermeier]

Hello,

who can give me an example, how to use the html:select in conjunction with
html:options? I had already defined an ActionForm and JSP like follows. The
listing of the option-Elements works fine but not the "reshowing" of the
selected elements of the list, because after I have clicked the submit
button I've got an IllegalArgumentException (BeanUtils.populate):

java.lang.IllegalArgumentException: argument type mismatch

at
org.apache.commons.beanutils.PropertyUtils.setProperty(PropertyUtils.java:17
13)
at org.apache.commons.beanutils.BeanUtils.setProperty(BeanUtils.java:1019)
{...}

My FormBean looks like this:
{...}
public final class RoleEditForm extends ActionForm {
{...}public void setAllUsers(ArrayList allUsers)
 this.allUsers = allUsers;}public ArrayList getAllUsers()
 return this.allUsers;}
{...}}
The allUsers list contains user objects. The user objects have the accessor
methods getId(), getName().
My JSP looks like this:





After clicking the submit button I've got the Exception. That's wrong?

Thank you very much!
Regards
Stephan

Check if you have month & day properties defined in your form bean.

Need help with html:select and html:options

[Scott Seong]

Hello,

I'm having trouble with html:select and html:options. Basically, I have
three select/options pairs in a JSP page, and the result is complaining
about "No getter method available for Property month for bean name under
org.apache...". Here is the code sample:

<%
Vector states = new Vector();

states.add(new LabelValueBean("Alabama", "AL"));

states.add(new LabelValueBean("Alaska", "AK"));

...

pageContext.setAttribute( "states", states);

Vector months = new Vector();

months.add(new LabelValueBean("Month", "00"));

months.add(new LabelValueBean("January", "01"));

...

pageContext.setAttribute( "months", months);



Vector days = new Vector();

days.add(new LabelValueBean("Day", "00"));

days.add(new LabelValueBean("1", "01"));

...

pageContext.setAttribute( "days", days);

%>


Then, I have html:select and html:options tags as shown below:




















The JSP chokes at the 2nd select/options, and I don't know why. If I remove
2nd and third pair, the JSP seems to work fine. Can someone help?

Thanks,
Scott

html:select and html:options tags

[Viet Kevin]

Hello all

My question is about the struts html:select and html:options tags

public class xxxForm extends ActionForm 
{
private Person choosed;
private Collection persons;


public get...
// accessors for this attributes are defined but I do not display
// them
}

When creating the form I set the choosed properties to firs instance in the persons 
list
xxxForm.setChoosed(xxxForm.getPersons.iterator.next());

Then I want to display that list in a html page for selecting a person in that list.
The html select must list all the persons AND the chooseen one must be displayed first 
(setting the html-attibute selected="selected" for the choosen one)

The other problem is that I want to use an index (an int that index the instances in 
the list) as the value
of the html option tag (not the name of the person)

so the html produced must be something like : 

 John  
 Henri 
 Max 


I play a lot of time trying to obtain this result with the struts tags 
but never figured out how to do it

Please tell me if it is possible to do or propose me an other solution
but I must have an index in my list so the value in the option tag must 
be an int


And the last question is I can't see what the attribute named tabindex in the 
html:select
tag is used for?

Thx in advance

There are two possible scenarios, depending on how big the various lists
of options for the second select box is.

* You can use Javascript to detect changes in the first select box,
  and dynamically change the contents of the second box.  This requires
  that the various choices for the second box are small enough to have
  been included in the page -- perhaps as Javascript arrays of strings.

* You can use Javascript to detect changes in the first select box,
  and then submit the form for you.  You'll need to tell the Action that
  receives the form that this is *only* being submitted to repopulate
  the second select box -- perhaps by setting the value of a particular
  hidden variable in the form -- so that it will just redisplay the form
  with the updated values.

None of this is really particular to Struts -- we're stuck with the
capabilities of HTTP and HTML that we are running on top of.

RE: accessing user-defined classes from html:select and html:options tags

[Philip Tucker]

I added the import statement, but still get the same error.  It's in a
Struts method called "BeanUtils.populate".  I have the imported class in my
.WAR file, and I even tried placing it directly in the server class path,
but still the same error.  Any ideas?

Below is the full error text.

accessing user-defined classes from html:select and html:options tags

[Philip Tucker]

I'm using Struts 1.0 with Tomcat 3.2.2 and JBoss 2.2.2.  I'm using an
 containing an  tag in a JSP, with the property
attributes referring to form and bean fields.  It works fine when the Java
class of the 2 bean properties is String, but when I try to use class I
created I get an error.  I've verified my .class file is in the deployment
WAR file.

Do I have to do something special to use my own class?  Do I need an import
statement in the JSP?

Thanks,
Philip

RE: how to set the default selected value using html:select and html:options

Doh, found my problem... my form bean name was capitalised in my

yes, it does what you'd expect it to. selects the label that
corresponds to the value of the property in the form bean.

i'd recommend checking out the exercise-taglib examples. there are
samples of how to drive most of the html tags.

Title: forms and javascript



Hi 
guys, just wondering if I've misunderstood the workings of the html:select and 
html:options tag. Is it true that html:options tag will automatically set 
the default selected value to that of the property declared in html:select? or 
is there a need to set the value explictly using the "value" 
attribute?
 
I'm 
assuming the former but it sure as hell isn't showing on my form. Any 
advice?
 
Cheers
Sidney
