I wrote a custom component that extends HTMLInputDate and it works
wonderfuly... asides for when I navigate away from the page that it is on.
When I do that I get the following exception:
java.lang.NullPointerException

Line 326 of HTMLInputDate:
boolean isDateSubmitted = ! (StringUtils.isEmpty(getDay()) &&
getMonth().equals("-1") && StringUtils.isEmpty(getYear()));
My Renderer:
public class WikiDateRenderer extends HtmlDateRenderer {
@Override
public void encodeBegin(FacesContext context, UIComponent component)
throws
IOException {
WikiDate wikiComponent = (WikiDate) component;
WikiRenderer wikiRenderer =
WikiRenderer.getAppropriateInstance(context,
wikiComponent);
wikiRenderer.encodeBegin();
if (wikiComponent.isWikiEnabled()) {
super.encodeBegin(context, component);
}
}
@Override
public void encodeEnd(FacesContext context, UIComponent component)
throws
IOException {
WikiDate wikiComponent = (WikiDate) component;
WikiRenderer wikiRenderer =
WikiRenderer.getAppropriateInstance(context,
wikiComponent);
if (wikiComponent.isWikiEnabled()) {
super.encodeEnd(context, component);
}
wikiRenderer.encodeEnd((new SimpleDateFormat("MMM dd, yyyy"))
.format(wikiComponent.getValue()), true);
}
}
My Component:
public class WikiDate extends HtmlInputDate implements WikiComponent {
public static final String DEFAULT_RENDERER_TYPE =
"com.loomis.jsf.component.wiki.WikiDateRenderer";
public static final String COMPONENT_TYPE =
"com.loomis.jsf.component.wiki.WikiDate";
private Boolean wikiEnabled;
public WikiDate() {
setRendererType(DEFAULT_RENDERER_TYPE);
}
public Object saveState(FacesContext context) {
Object[] values = new Object[2];
values[0] = super.saveState(context);
values[1] = wikiEnabled;
return values;
}
@Override
public void restoreState(FacesContext context, Object state) {
Object values[] = (Object[])state;
super.restoreState(context, values[0]);
if (values[1] != null) setWikiEnabled((Boolean) values[1]);
}
public Boolean isWikiEnabled() {
Object objVal = LSComponentUtil.getValue(this,
getFacesContext(),
"wikiEnabled", Boolean.TRUE);
return wikiEnabled != null ? wikiEnabled : (Boolean)objVal;
}
public void setWikiEnabled(Boolean wikiEnabled) {
this.wikiEnabled = wikiEnabled;
}
}
Thank you! :-)
