Hi Heath
Thanks for the solution... it does sound complicated, but I am trying it.
I am using version 1.0.7 of my-faces.
I have changed the onclick event of the checkbox to call the click event of
the command button, nothing happened. Here is part my page....
<h:panelGrid id="remarriedOption" columns="2" >
<seniorfaces:outputLabel for="remarried"
value="some text here ?" />
<h:selectBooleanCheckbox id="remarried"
immediate="true"
onclick="document.getElementById('hiddenBtn').click();"
value="#{manageProfileFace.spouseHelper.remarried}" />
<h:commandButton id="hiddenBtn"
style="display:none;"
action="#{manageProfileFace.spouseHelper.flagRemarried}" />
</h:panelGrid>
<h:panelGrid id="remarriageInfo" columns="2"
rendered="#{manageProfileFace.spouseHelper.remarried}"
styleClass="dataTableBorderAlt"
rowClasses="dataCellEven,dataCellOdd"
columnClasses="cellAlignLeftFullWidth,cellAlignLeftFullWidth"
cellpadding="0"
cellspacing="1">
<seniorfaces:outputLabel for="firstName"
value="First Name" />
<h:inputText id="firstName"
required="#{manageProfileFace.spouseHelper.remarried}"
value="#{manageProfileFace.spouseHelper.newSpouse.firstName}">
<f:validateLength maximum="20"/>
</h:inputText>
<seniorfaces:outputLabel for="middleName"
value="Middle Name" />
<h:inputText id="middleName"
value="#{manageProfileFace.spouseHelper.newSpouse.middleName}">
<f:validateLength maximum="20"/>
</h:inputText>
<seniorfaces:outputLabel for="Last Name"
value="Last Name" />
<h:inputText id="Last Name"
required="#{manageProfileFace.spouseHelper.remarried}"
value="#{manageProfileFace.spouseHelper.newSpouse.lastName}">
<f:validateLength maximum="30"/>
</h:inputText>
....
....
</h:panelGrid>
the method "flagRemarried" will toggle the flag in the backing bean. Will the
getElementById work with version 1.0.7 ? What am I missing here ? When the
checkbox is clicked nothing is happening.
Please reply at your convenience. I am off for the day.
Thanks
Srikanth

Subject: Re: handling the required attributes
Just to preface, this solution is a bit complicated.
First, you shouldn't do a form submit when the user clicks the
checkbox. You should create an immediate commandButton and set its
style to "display: none;". This will hide it from the user, but still
allow you to use it to generate ActionEvents.
When the user clicks the checkbox, you do a
"document.getElementById('myCommandButton').click();", which will
submit the form using your commandButton.
This will allow the user to uncheck the checkbox without having validation run.
However, now you will have other problems:
All UIInputs on the form will not be validated, so none of their
values will get push to the models. You can solve this problem by
making the UIInputs you want to go through to the models (probably
just your checkbox) immediate as well. This will get them through
their process validators phase. Additionally, you have to register a
ValueChangeListener on those UIInputs that will call the UIInput's
updateModelValues() method.
Finally, you have to traverse the JSF tree and clean all the
submittedValues/values from all UIInputs, or else they will not
properly pull from their models on the fresh request.
I said it would be complicated :-)
