Hi!
I have two questions regarding forms. I think they are quite simply - for you,
not for me ;-)
1) Leaving a page without validation.
I have a form (see 2) with input field that are validates, e.g. a
required="true". The validation should be checked if the OK submit button is
hit. This works fine. But when the Cancel button is hit, the validation should
not be checked.
So how can I enable/disable the validation depending on the button clicked?
2) One button missing in the rendered page.
See the jsp page snippet below (*1). The button "Cancel" is not rendered in the
resulting html page. When I put the form tag around the two buttons in the
footer facet (see *2) , both buttons are rended. Why?
Thank you for your help in advance
================== (*1) Button missing ===============
<h:form>
<h:panelGrid columns="3" styleClass="standardDialog"
headerClass="standardDialogHeader"
footerClass="standardDialogFooter">
<f:facet name="header">
<h:outputText value="Einstellungen" />
</f:facet>
<h:outputText value="Max. Anzahl der angezeigten Objekte:" />
<h:inputText id="maxobj" value="#{prefs.maxObjectCount}"
maxlength="5"
size="10" required="true" />
<h:message for="maxobj" styleClass="error" />
<h:outputText value="Teilmengen von Objekten anzeigen" />
<h:selectBooleanCheckbox id="showSubsets"
value="#{prefs.showObjectsInSubset}" />
<h:message for="showSubsets" styleClass="error" />
<f:facet name="footer">
<h:commandButton value="OK"
action="#{prefs.outOk}" />
<h:commandButton value="Cancel"
action="#{prefs.outCancel}" />
</f:facet>
</h:panelGrid>
</h:form>
