I'm trying to dynamically build a form by looping over a set of fields that
have a renderer attribute, which is used to tell what widget should be used to
renderer them.
The problem I'm facing is when the widget is a select element. In this case,
the nested f:selectItems load their data from a bean that, if I understand well
the documentation, cannot be specified at runtime. Thus, I have hardcoded the
bean that provides the data to the select boxes (dataProviderBean.selectItems
in my simplified example below). But when the form is rendering, I haven't
found any mean by which dataProviderBean can know which select element is being
populated.
What's the best approach for solving this problem ?
| <h:dataTable var="field" value="#{fieldSet}">
| <h:column>
| #{field.name}
| </h:column>
|
| <h:column>
| <h:inputText value="#{field.value}"
| rendered="#{field.renderer.isInputText}"/>
|
| <h:selectManyListbox value="#{field.value}"
| rendered="#{field.renderer.isManyListBox}">
| <f:selectItems value="#{dataProviderBean.selectItems}"/>
| </h:selectManyListbox>
|
| <h:selectManyCheckbox value="#{field.value}"
|
rendered="#{field.renderer.isManyselectManyCheckbox}">
| <f:selectItems value="#{dataProviderBean.selectItems}"/>
| </h:selectManyCheckbox>
| </h:column>
| </h:dataTable>
