autoComplete value not set to null

[vlkn]

Hi!

I have a problem with autoComplete component. It's value is set to be bound to object, it has implemented and registered converter with the following snippet:

Code: Select all

<p:autoComplete id="catalogue"
	value="#{taskBean.catalogue}" var="catalog"
	itemValue="#{catalog}" itemLabel="#{catalog.label}"
	completeMethod="#{catalogueListBean.completeByQuery}"
	minQueryLength="2" maxResults="14">
	<f:converter converterId="catalogueConverter" />
</p:autoComplete>

It's working properly when value is set. But, if backing bean property is set, I just don't know how to set it's value back to null. If I delete contents from autoComplete field, it keeps previous value, it doesn't reset it to null. By logging in converter, I notice that component sends old value.

How can I set value back to null?

Thanks in advance.

I know it must be something trivial, but I just can't find the answer. Anyone?

How can autoComplete set backing bean property value back to null?

You submit the form after clearing the input right? Also can you post the code of your converter?

Thank you for your reply.

Yes, I clear the input and it is empty and it stays empty until submit. After, due to value binding, it gets same value as before clearing input.

My converter's methods are:

Code: Select all

public Object getAsObject(FacesContext arg0, UIComponent component, String arg2) throws ConverterException {
	if (arg2 == null || arg2.length() == 0) {
		if (component instanceof EditableValueHolder) {
			((EditableValueHolder) component).setSubmittedValue(null);
		}
		return null;
	}
	String[] parsed = arg2.split(";");
	Catalogue catalogue = new Catalogue();
	catalogue.setId(Integer.parseInt(parsed[0]));
	catalogue.setLabel(parsed[1]);
	return catalogue;
}

public String getAsString(FacesContext arg0, UIComponent arg1, Object arg2) throws ConverterException {
	if (arg2 == null || !(arg2 instanceof Catalogue)) {
		return "";
	}
	return String.format("%s;%s", Integer.toString(((Catalogue)arg2).getId()), ((Catalogue)arg2).getLabel());
}

Can you replicate this case with showcase?

Well, after trying to submit values on ShowCase, I noticed that there value is also remembered. If, for example, I enter there Messi and click on Submit button, message "Selected: Messi" is displayed. If I clear input and click on Submit once again, same message is displayed.
