Filling values into standard fields in PE

Long long ago I posted a blog about updating other object's status automatically. I have been planning for the next blog ever since. Finally took a break and posting one of the trick which I used in one of the project or implementation.

You all might know that in PE (Professional Edition) you can't write apex codes. That cuts off building much complex functionality from the instance. But sometimes clients are so adamant that they don't understand (or try so) developer's pain of inability of building the process that requires coding. Why? Because they have paid money!!

One of such situation which I recently came across: To re-use the Opportunity as Tender, but Stages should be different!! Here Opportunity Name cannot be used, as Tender Number (auto number) needs to be copied to the name. I could have used Tender as a custom object, but if I

did I had to re-do the standard functionality of adding products, quotes. Adding Products can be done with a junction object, but what about Quote, syncing etc?? Remember, it is PE. Hence had to reuse the Opportunity object.

Now the problem of overriding Opportunity Stage values with Tender Stage and copying the Tender Number to name to be solved. Obvious solution for different stages would be merging both Opportunity stages and Tender Stages into Stage field OR overriding with a VF

page and hiding the Stage. The first one is gonna piss-off the client (obviously design is not good), the latter looks promising but the Stage field is mandatory and it cannot be updated

through workflow because validation is executed before workflow. Did workflow field update (yes, this client had purchased workflow along with PE) come to your mind for copying the value? It doesn't work as (again) validation rule are executed before workflow field updates, hence it shows error on Name field.

Enough of dragging the problem, coming to the solution: Create 2 VF pages - one for Opportunity and other for Tender. Create 2 list buttons - New Opportunity and New Tender, these will be shown under Account, in Opportunity related list. We won’t have any problem with Opportunity VF as we are gonna use all standard fields. Problem would be with

Tender VF. Solution for this is to fill the mandatory field values through JavaScript. Hide the Stage, CloseDate, Name (or any other standard fields) from VF page and in the background fill some values in them.

Here is the Visualforce page code with some
JavaScript trick:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45

<apex:page id="page_opp" standardcontroller="Opportunity"> <apex:form id="form_opp"> <script type="text/javascript"> function addLoadEvent(func) { var oldonload = window.onload; if (typeof window.onload != 'function') { window.onload = func; } else { window.onload = function() { if (oldonload) { oldonload(); } func(); } } } addLoadEvent(test); function test() { var d=new Date(); document.getElementById("{!$Component.j_id2:gen:cls}").value = d.getDate() + '/' + (d.getMonth()+1) + '/' + d.getFullYear(); document.getElementById("{!$Component.j_id2:gen:stg}").value = "SomeStageValue"; } </script> <apex:sectionheader subtitle="New Tender" title="Tender Details" /> <apex:pageblock title="Tender Information"> <apex:pagemessages/> <apex:pageblockbuttons location="Both"> <apex:commandbutton action="{!Save}" value="Save" /> <apex:commandbutton action="{!Cancel}" value="Cancel"/> </apex:pageblockbuttons> <apex:pageblocksection id="gen" showheader="false" title="General"> <apex:inputfield label="Tender Name" value="{!Opportunity.Name}" /> <apex:inputhidden id="stg" value="{!Opportunity.StageName}" /> <apex:inputhidden id="cls" value="{!Opportunity.CloseDate}" /> <apex:inputfield value="{!Opportunity.Tender_Authority__c}" /> ..... ... .. </apex:pageblocksection> </apex:pageblock> </apex:form> </apex:page>

As you can see, on load we are updating or inserting some values into those standard fields.

Comments are expected as there can be other ways of doing this. If you have any idea please share..
