RE: Obtaining check box data from a form
Pretty much. There may be a way, but it is coded in the HTML. However, I don't think you need to do so. Or rather I don't think you should need the values that were displayed, they should be hard-coded text in an HTML form. Why do you need the text that is in the HTML? Name: Mark J.

RE: Obtaining check box data from a form
Peter,
Checkboxes are like any other field.
HTML:
Allowable SAML Bindings
Artifact
POST
Redirect
SOAP
JWC:
JAVA:
private boolean artifactBinding = true;
private boolean postBinding = true;
private boolean redirectBinding = true;
private boolean soapBinding = true;
public boolean isArtifactBinding()
{
return artifactBinding;
}
public void setArtifactBinding(boolean artifactBinding)
{
this.artifactBinding = artifactBinding;
}
public boolean isPostBinding()
{
return postBinding;
}
public void setPostBinding(boolean postBinding)
{
this.postBinding = postBinding;
}
public boolean isRedirectBinding()
{
return redirectBinding;
}
public void setRedirectBinding(boolean redirectBinding)
{
this.redirectBinding = redirectBinding;
}
public boolean isSoapBinding()
{
return soapBinding;
}
public void setSoapBinding(boolean soapBinding)
{
this.soapBinding = soapBinding;
}
All you have to do is put 1-n in an HTML template. I have mine declared in the
.jwc, but you could just put it in the HTML. Then link them to some method in
a java class somewhere. I have mine updating a visit object value
"currentState". "Current State" is the users "current state". Pick a java
object somewhere.
The values of the boolean values will be displayed as checked or unchecked just
as the data is in the java object. If the user checks or unchecks a checkbox
and submits it then the java method is called. The end result is that the java
boolean values are displayed and modifiable by your users. When submitted they
automatically populate your java values. No different than a Text Input Field.
hth,
Mark

Re: Re: Obtaining check box data from a form
The Tapestry Checkbox component doesn't offer a way to do what you
want but it is possible to do it. If you have multiple input fields
with the same name, the servlet spec says that you can call
request.getParameters("fieldName") and receive an array of strings.
So here's how I solved this:
Write some code that renders a plain rather than using Tapestry Checkbox
component. If you want to make it a component, one very similar to
existing Checkbox, then so much the better.
Now make another component called CheckboxGroup. Include a listener
method which will get executed whenever the CheckboxGroup is rewound.
Your custom Checkbox component can check if the current Container is a
CheckboxGroup. if it is, get the name from the CheckboxGroup. Then,
in your Group listener, call getWebRequest().getParameters("myName")
to retrieve a String[] of values. Now, if necessary, convert the
string to an actual object. Then assign the array to the appropriate
place. html would look something like this:
Although in our case, we skipped the CustomCheckbox component
entirely. We just pass a SelectionModel to the CheckboxGroup, and use
the label and value properties to render a checkbox from the render
method of the CheckboxGroup. We can fetch the values during the
rewind method of the same component. And some simple ognl
manipulations on the name parameter can allow you to assign the
resulting values to the named object/property.
Of course, I have no idea if any of this will work in Tap3, but in my
case, it was only a couple of hours in Tap4, mostly spent figuring out
what changes I needed to make to the contrib:MultiplePropertySelection
and contrib:CheckBoxMultiplePropertySelectionRenderer. The code was
easy enough to understand and modify to my own needs.

Re: Obtaining check box data from a form
Most of the time a checkbox - by definition - is more of a boolean operation
than value...But far be it from me to argue with semantics that do work..
If you want to just get past the problem and move on you can always call
IRequestCycle.getParameterValues("thenameyou gaveallofyourcheckboxes");

Re: Obtaining check box data from a form
ok i will try again. i have a bunch of options which the user can select from. they are all checkboxes (approx say 25). based on this user selection i display corresponding information on the next page. now first thing, 1. how should i group these checkboxes, individually, within a span or something else (multiplepropertyselection) 2. once the user selects their options and presses submit, i want to gather the data from all selected checkboxes. i hope this is better. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Obtaining check box data from a form
Hi Peter. Your explanation is rather vague, but if you want to treat the checkboxes as a group, you might want to look at the contrib MultiplePropertySelection: http://tapestry.apache.org/tapestry3/doc/api/org/apache/tapestry/contrib/form/MultiplePropertySelection.html Note that all the html docs are included in the Tapestry download. Cheers, Nick.
