Governor limits when using 4 VF pages in one VF page.

A Question to the boarders:
If I am using apex:include to include 4 VF pages in another VF page, Will it take governor limits for each separately Or is it combined? And suppose that those 4 VF pages have their own controllers. I think the limits are separate for each page. Like to know what others think about this. Probably someone has a solid answer....

 

Thanks....

limits are page request based, so I would expect all pages loaded are seen as a single request, with a single set of limits.

Sdry is correct.

 

Each transaction will have a governor limit equal to the initial request (e.g. if it is a Visualforce page, the VF governor limits apply, even if DMLs that call triggers are in effect).

 

I created three pages that illusrate this effect:

 The source is as follows:

 

incl.page:

 

<apex:page >
    <apex:include pageName="{!$Page.inc1}" />
    <apex:include pageName="{!$Page.inc2}" />
</apex:page>

inc1.page:

 

<apex:page controller="inc1">
    {!name}
</apex:page>

inc2.page:

 

<apex:page controller="inc2">
    {!name}
</apex:page>

Inc1.class:

 

public with sharing class inc1 {

    public String getName() {
        return [select id,name from account limit 1].name;
    }

}

inc2.class:

 

public with sharing class inc2 {

    public String getname() {
        return [select id,name from contact limit 1].name;
    }
}

When you read the logs, you will see the cumulative usage is 2 statements, 2 rows returned. This empirically proves that the usage is cumulative across all pages.
