How to re-create the Task page in VF with whoid and whatid filled in??? Help please

Hi:

I want to re-create the Task Page in Visualforce and have the Whoid and what id filled in. Now, I can get this to work if I dont use the VF task page and use the standard task page. But I can not get it to work on the VF Page??/

Basically a user will click new task and it will open up this VF task page and have the whoid and whatid filled in automatically through URL. Do not know how to:

public PageReference Monitor(){

    moni = new List<History__c>(
            [SELECT  id,
            Student__c
            FROM History__c 
            where Student__c=:ApexPages.currentPage().getParameters().get('oppIdd')
            AND id=:ApexPages.currentPage().getParameters().get('oppIddc')
            ]);
 
    
   //PageReference newpage = new PageReference('/00T/e?who_id=' + monitorstudent[0].Student__c+ '&what_id=' + monitorstudent[0].Id + '&retURL=%2Fhome%2Fhome.jsp');
    PageReference newpage = new PageReference('/apex/Task?who_id=' + monitorstudent[0].Student__c+ '&what_id=' + monitorstudent[0].Id );

        newpage.setRedirect(true);
        return newpage; 
} 
<apex:page standardController="Task" sidebar="false">

    <apex:form >
        <apex:pageBlock title="Edit Task" id="thePageBlock" mode="edit">
            <apex:pageMessages />
            <apex:pageBlockButtons >
                <apex:commandButton value="Save" action="{!save}"/>
                <apex:commandButton value="Cancel" action="{!cancel}"/>                
            </apex:pageBlockButtons>
            <apex:actionRegion >
                <apex:pageBlockSection title="Basic Information" columns="1">
                <apex:inputField value="{!Task.Ownerid}"/>
                    <apex:pageBlockSectionItem >
                        <apex:outputLabel value="Subject"/>
                            <apex:inputField value="{!Task.Subject}"/>
                    </apex:pageBlockSectionItem>
                    <apex:inputField value="{!Task.whoid}"/>
                    <apex:inputField value="{!Task.whatid}"/>
                </apex:pageBlockSection>
            </apex:actionRegion>

        </apex:pageBlock>
    </apex:form>

</apex:page>

Please help me figure this out. Thanks

Here it goes....

<apex:page standardController="Task" sidebar="false" extensions="extensionsEx">

    <apex:form >
        <apex:pageBlock title="Edit Task" id="thePageBlock" mode="edit">
            <apex:pageMessages />
            <apex:pageBlockButtons >
                <apex:commandButton value="Save" action="{!save}"/>
                <apex:commandButton value="Cancel" action="{!cancel}"/>
            </apex:pageBlockButtons>
            <apex:actionRegion >
                <apex:pageBlockSection title="Basic Information" columns="1">
                <apex:inputField value="{!Task.Ownerid}"/>
                    <apex:pageBlockSectionItem >
                        <apex:outputLabel value="Subject"/>
                            <apex:inputField value="{!Task.Subject}"/>
                    </apex:pageBlockSectionItem>
                    <apex:inputField value="{!Task.whoid}"/>
                    <apex:inputField value="{!Task.whatid}"/>
                </apex:pageBlockSection>
            </apex:actionRegion>

        </apex:pageBlock>
    </apex:form>

</apex:page>

class:

public with sharing class extensionEx{

    Task task = new Task();

    public extensionEx(ApexPages.StandardController controller) {
      this.task = (Task)controller.getRecord();
      string strWhatId = System.currentPage().getParameters().get('oppIdd');
      string strOwnerId = System.currentPage().getParameters().get('ownerId');
      Task.WhatId = strWhatId ;
      Task.OwnerId = strOwnerId ;

    }

}

Cheers :)

Hi srinivas,

For some reason your code does not compile in my org.

What its saying is in the constructor of the controller extension,

Error: Compile Error: Method does not exist or incorrect signature: System.CurrentPage() at line 7 column 26.

I replaced the System.Currentpage() with ApexPages.Currentpage() and it got compiled and saved.

But when i execute the Vf by passing an Id (Task ID) it raises run time exception and does not populate it with owner id.

Am i doing anything wrong. I am trying to learn, but got stuck out here.

Any help/idea on this is highly appreciated.

Thanks,

Sales4ce

Hi Srinivas,

Thanks for your help!.

Here is the code:

public with sharing class taskExtension
{
    Task tsk=new Task();
    public taskExtension(ApexPages.StandardController controller)
    {
        this.tsk=(Task)controller.getRecord();
        String strWhatId=ApexPages.CurrentPage().getParameters().get('id'); // Here if i give System.CurrentPage().getParameters().get('id') gives me compilation error.
        String strOwnerId=ApexPages.CurrentPage().getParameters().get('OwnerId');
        tsk.WhatId=strWhatId;
        tsk.OwnerId=strOwnerId;
    }

}

Here is the VF Page:

<apex:page standardController="Task" sidebar="true" extensions="taskExtension" >
<apex:form >
<apex:pageblock title="Edit Task" id="taskId" mode="Edit">
<apex:pageMessages />
<apex:pageBlockButtons >
<apex:commandButton value="Save" action="{!Save}"/>
<apex:commandButton value="Cancel" action="{!Cancel}"/>
</apex:pageBlockButtons>

<apex:pageBlockSection title="Basic Information" columns="2">
<apex:InputField value="{!Task.OwnerId}"/>
<apex:InputField value="{!Task.Subject}"/>
<apex:InputField value="{!Task.WhoId}"/>
<apex:InputField value="{!Task.WhatId}"/>
</apex:pageBlockSection>

</apex:pageblock>
</apex:form>

</apex:page>

Thanks,

Sales4ce

public with sharing class taskExtension
{
    Task tsk=new Task();
    public taskExtension(ApexPages.StandardController controller)
    {
        this.tsk=(Task)controller.getRecord();
        String strWhatId=ApexPages.CurrentPage().getParameters().get('id');
        String strOwnerId=ApexPages.CurrentPage().getParameters().get('OwnerId');
        tsk.WhatId=strWhatId;
        tsk.OwnerId=strOwnerId;
    }

}

Did anyone ever find the solution to the compile error. I, too, get "Method does not exist or incorrect signature: System.currentPage()"

@megmooPDX you need to use ApexPages instead of System.currentPage()

@Sales4ce has a good example above

ApexPages.CurrentPage().getParameters().get('id')
