                                                       throws java.io.IOException
Render the javascript function that is called on a click on a commandLink to clear the hidden inputs. This is necessary because on a browser back, each hidden input still has it's old value (browser cache!) and therefore a new submit would cause the according action once more!

Parameters:
writer -
formName -
dummyFormParams -
formTarget -
Throws:
java.io.IOException

getClearHiddenCommandFormParamsFunctionName

public static java.lang.String getClearHiddenCommandFormParamsFunctionName(java.lang.String formName)
Prefixes the given String with "clear_" and removes special characters

Parameters:
formName -
Returns:
String

getFormName

public static java.lang.String getFormName(javax.faces.component.UIComponent component,
                                           javax.faces.context.FacesContext context)
Return the clientId of the form associated with the specified component.

If the component is nested within a UIForm, that component's id is returned.

Otherwise the component of the "dummy form" is returned. At most one dummy form is output into each page; all components which can cause page submission but are not nested within a real form will cause the dummy form to be submitted instead.

getHiddenCommandLinkFieldName

public static java.lang.String getHiddenCommandLinkFieldName(java.lang.String formName)
Get the name of the request parameter that holds the id of the link-type component that caused the form to be submitted.

Within each page there may be multiple "link" type components that cause page submission. On the server it is necessary to know which of these actually caused the submit, in order to invoke the correct listeners. Such components therefore store their id into the "hidden command link field" in their associated form before submitting it.

The field is always a direct child of each form, and has the same name in each form. The id of the form component is therefore both necessary and sufficient to determine the full name of the field.

getSupportedContentTypes

public static java.lang.String[] getSupportedContentTypes()

isXHTMLContentType
