I have come to a conclusion that either there has to
be way to submit an VXML page with field names like
"cocoon-xmlform-view" (Is there any way? I could not
find one) like this
<submit method="get" next="wizard?"
namelist="cocoon-xmlform-view city propertyType rent
cocoon-action-next"/>
(As I mention earlier VXML browser throws and
ECMAScript exception cuz of "-" in the variable name)
or we need to make changes in XMLForm so that it is
in true practical sense "Device Independent Form".
By looking around the src I found out that Form.java
of XMLForm uses some constants from Constants.java
The following is the snippet of same:
from Form.java
snip--
public static String FORM_VIEW_PARAM =
"cocoon-xmlform-view";
snip--
/**
* filters custom request parameter
* not refering to the model
*
* @todo implement default filtering
* for standard Cocoon parameters
* like cocoon-action[-suffix]
*
*/
protected boolean filterRequestParameter( String
name )
{
// filter standard cocoon-* parameters
if ( filterDefaultRequestParameter( name ) )
return true;
// then consult with FormListeners
Set ls = new HashSet();
ls.addAll( Collections.synchronizedSet (
formListeners_ ) );
Iterator iter = ls.iterator ();
while (iter.hasNext())
{
FormListener fl = (FormListener) iter.next();
// if any of the listeners wants this parameter
filtered
// then filter it (return true)
if ( fl.filterRequestParameter( this, name ) )
return true;
}
// if none of the listeners wants this parameter
filtered
// then don't filter it
return false;
}
/**
* Filters the standard cocoon request parameters.
* If default filtering needs to be different,
* subclasses can override this method.
* It is invoked before all listeners are asked to
filter the parameter
*/
protected boolean filterDefaultRequestParameter(
String paramName )
{
if ( paramName.startsWith (
Constants.ACTION_PARAM_PREFIX )
|| paramName.startsWith ( Constants.VIEW_PARAM
)
)
return true;
if ( paramName.equals ( FORM_VIEW_PARAM ) )
return true;
else return false;
}
/**
* Try to extract from the request
* and return the current form view
*/
public String getFormView( Map objectModel )
{
Request request =getRequest( objectModel );
return (String) getRequest( objectModel
).getParameter ( Form.FORM_VIEW_PARAM );
}
*******************************************************
from Constants.java
snip--
/**
* The request parameter name to request a
specific view of a resource.
*
* FIXME(GP): Isn't this Servlet specific?
*/
String VIEW_PARAM = "cocoon-view";
/**
* The request parameter name to trigger a
specific action.
*
* FIXME(GP): Isn't this Servlet specific?
*/
String ACTION_PARAM = "cocoon-action";
/**
* The request parameter prefix to trigger a
specific action.
*
* FIXME(GP): Isn't this Servlet specific?
*/
String ACTION_PARAM_PREFIX = "cocoon-action-";
*****************************************************
So I am not sure if we need to fix this, if we need to
do v have to change the constants??
Or is there any other solution to this?
