submitting and reading data 'from request'

gajos Sep 26, 2008 1:28 AM

Hi,

I'm using Seam framework and have the following problem:
how to submit and read the values 'from the request' of a dynamically built form ?

I do not have a 'static' entity with attributes (defined classes), my entities are defined on the fly
and being displayed in the following way:
I built a form by modifying component tree :

Application application = FacesContext.getCurrentInstance().getApplication();
List<UIComponent> childern = panel.getChildren();
childern.clear();

and adding to children list the attributes (javax.faces.component.html.HtmlInputText objects).
Panel object is within h:form and /h:form tags. Then I would like to submit this form
and read somehow the values.

Does anyone have an idea ? Maybe there is any other way to handle this problem ?

Thanks in advance,
Michal

I have built dinamic forms, and what I do is that I bind the form controls to keys in a java.util.Map.

Thanks a lot, one more thing - how to submit this form ? If I put a button into the form e.g.

<s:button action='#{controller.update}' value='Update'/>

all fields that I will modify on the page will be updated in the Map ?

<a:repeat value="#{controller.fieldList}" var="field"> <h:outputText value="#{field.name}"/> <h:inputText #{controller.valueMap[field]}/> </s:decorate> </a:repeat>

Yes, they will be updated into the java.util.Map.

no, they are not updated with:

<s:button action='#{controller.update}' value='Update'/>

but only if I use:

<h:commandButton action="#{controller.update}" value="Update"/>

many thanks Francisco, you helped me :)

Yes, sorry, you are right, you have to use <h:commandButton not <s:button, because it does not submit the form.
