In a view scoped managed bean, I'm using <p:resetInput> to clear the values held by the properties in the corresponding manged bean like,
<p:commandButton value="Reset" update="panel" process="@this">
<p:resetInput target="panel" />
</p:commandButton>
This works fine.
I have a submit button <p:commandButton> which when pressed causes the submitted values to be inserted into the database, if validation succeeds.
<p:remoteCommand name="updateTable" update="dataTable"/>
<p:panel id="panel" header="New">
<p:outputLabel for="property1" value="property1"/>
<p:inputText id="property1" value="#{bean.property1}" required="true">
<f:validateLength minimum="2" maximum="100"/>
</p:inputText>
<p:message for="property1" showSummary="false"/>
<p:commandButton id="btnSubmit"
update="panel messages"
oncomplete="if(!args.validationFailed) {updateTable();}"
actionListener="#{bean.insert}"
value="Save"/>
<p:commandButton value="Reset" update="panel" process="@this">
<p:resetInput target="panel" />
</p:commandButton>
</p:panel>
The command button invokes the insert() method in the managed bean which is defined as follows.
public void insert() {
if (service.insert(property1)) {
//...Popup a success message.
reset(); //Invoke the following private method.
} else {
//...Show the cause of the failure.
}
}
private void reset() {
property1 = null; //Set this property of type String to null.
}
If this reset() method is omitted, then <p:inputText> will not be cleared as obvious but then if I press the reset button as shown in XHTML, <p:inputText> should be cleared but it doesn't.
The showcase example demonstrates exactly the same thing. Therefore, this behaviour appears to be documented but I don't understand why doesn't <p:resetInut> clear the value of property1, if the reset() method is omitted, in this case?
