Consider:
public void actionListener(ActionEvent event) {
FacesContext context = FacesContext.getCurrentInstance();
Map params = context.getExternalContext
().getRequestParameterMap();
params.put("myparam", "value");
One minor problem ... this (or the solutions below) will not work, because
the map returned by getRequestParameterMap() is immutable -- it cannot be
changed. In turn, this restriction comes from the fact that request
parameters are read only at the servlet API level ... you cannot change
them.
If you want to pass dynamically calculated information for this request to
some other part of the application, use request *attributes* instead.
Craig
// or
ValueBinding vb = context.getApplication().createValueBinding("#{
param.myparam}");
vb.setValue(context, "value");
// or
params = (Map)
context.getApplication().getVariableResolver().resolveVariable(context,
"param");
& nbsp;& nbsp; params.put("myparam", "value");
}
