I tried the following but could not get it to work:
<h:selectOneMenu id="areaCode" value="#{areaCodeBean.areaCode}">
<f:selectItems value="#{areaCodeBean.selectList}"/>
<f:param name="codeType" value="US.AREA_CODES" />
</h:selectOneMenu>
And in the BB to retrieve the codeType I have the following method that is
called:
private String getCodeType()
{
String codeType = (String)FacesContext.getCurrentInstance()
.getExternalContext().getRequestParameterMap().get("codeType");
return codeType;
}
---
When I look at the value for "codeType" it is always null. getCodeType is
called by
public List<SelectItem> getSelectList() {
// query from types table here and pass codeType (call to getCodeType()
which uses faces context
// to get a param set in the XHTML.
}
