I tried with this peace of code, whenever i change value alert appears but even reloading the page alert appears which shouldn't. How to skip alert on reloading the page.

<apex:page standardController="Case" rendered="{!Case.Stage__c = 'Pending'}">
<script type="text/javascript">
window.alert("Static Content");
</script>
</apex:page>

Also i tried in putting stage condition in action attribute but it is throwing Content cannot be displayed: SObject row was retrieved via SOQL without querying the requested field: Case.Stage__c [No Apex class associated to this page]
<apex:page standardController="Case" Action="{!Case.Stage__c = 'Pending'}">
<script type="text/javascript">
window.alert("Static Content");
</script>
</apex:page>


 

I have below JSON ,How can I send in my request using apex:

"objects":[
{
"fieldsToNull":["DefaultPaymentMethodId"],
"AccountNumber":"A00000036",
"Id":"2c92c0f95a4085a8015a41f4012d183e"
}
]
, "type":"Account"

Does salesforce lock Account Record when user try to update/create following child objects -

    AccountTeamMember

    Opportunity Line Item (Does sfdc lock opportunity here as well?)

    Task

    Contact

    OpportunityTeamMember (Does sfdc lock opportunity here as well?)

Is this applicable to only Master Detail relationships ? (Not Lookups)
