Parameters:

markupStream - The markup stream

openTag - The open tag for the body

protected boolean localizeDisplayValues()

Should display values be localized.

renderHead

public void renderHead(IHeaderResponse response)

Specified by:

renderHead in interface IHeaderContributor

Overrides:

renderHead in class Component

public void updateModel()

Overrides:

updateModel in class FormComponent<T>

getModelValue

protected String getModelValue()

Overrides:

getModelValue in class FormComponent<T>

Returns:

Value to return when model value is needed
