How to prefill a custom object?

Hi all,

 

I have a problem where i am trying to prefill a custom object whenever the Edit Button is clicked.

 

Here is my Controller Code. I am instantiating object in the constructor class. I pass the ID of the object through the URL:

 

public class newScoreRuleController { // Declarations  public List<ScoringRule__c> ScoringRule { get; private set;}  public List<MappingRule__c> mappingRule {get; private set;}public newScoreRuleController () {    // Give me blank lines of my Object    	 String op = ApexPages.currentPage().getParameters().get('op');    ScoringRule = new List<ScoringRule__c>();    for (integer i = 0; i < 8; i++) {        ScoringRule.add( new ScoringRule__c() );    }    if (op!='edit') {    MappingRule = new List<MappingRule__c>();    for (integer i = 0; i < 4; i++) {        MappingRule.add( new MappingRule__c() );    }   }   else {// Edit Operation chosen .. So prefill it   	 MappingRule = new List<MappingRule__c>();    MappingRule.add([Select rating__c, ScoreVal2__c, ScoreVal1__c,     							ScoreOperator2__c, ScoreOperator1__c, RuleSetId__c,     							Mapping_Field__c From mappingRule__c n where RuleSetId__c =: getRuleSetId()]);    	//MappingRule = mp;    }}
 
 // Get me the Rule Set ID
 public String getRuleSetId() {
      String ruleId = ApexPages.currentPage().getParameters().get('id');
    return ruleId;
  } 
}
 
  Here is my Visualforce Code:
 
 
	<apex:dataTable value="{!mappingRule}" var="mr">     <apex:column >     <apex:facet name="header">Score</apex:facet>     <apex:outputText value="Score"/>     </apex:column>     <apex:column >     <apex:facet name="header">Operator</apex:facet>     <apex:inputField value="{!mr.ScoreOperator1__c}"/>     </apex:column>          <apex:column >     <apex:facet name="header">Score Value 1</apex:facet>     <apex:inputText value="{!mr.ScoreVal1__c}"/>     </apex:column>          <apex:column >     <apex:facet name="header">Operator</apex:facet>     <apex:inputField value="{!mr.ScoreOperator2__c}"/>     </apex:column>          <apex:column >     <apex:facet name="header">Score Value 2</apex:facet>     <apex:inputText value="{!mr.ScoreVal2__c}"/>     </apex:column>     <apex:column >     <apex:facet name="header">Rating</apex:facet>     <apex:inputField value="{!mr.rating__c}"/>     </apex:column>	</apex:dataTable>
 
However it doesnt prefill the Object.  It doesnt complain either. So i really dont know whats happening?
 
Any help is appreciated!!!

Ok! So i was able to fix it. It seems like the Constructor was not calling the Set Method.
 
I created seperate get and set methods and it worked!

Hi Mukul,
 
Is it possible that the query [Select rating__c, ScoreVal2__c, ScoreVal1__c, ScoreOperator2__c, ScoreOperator1__c, RuleSetId__c, Mapping_Field__c From mappingRule__c n where RuleSetId__c =: getRuleSetId()] isn't returning any rows?

Hi successforce,
 
Thanks for replying. 
It returns rows. I have tried printing it out to the debug log.

Hi there,
 
You could try a couple of things to debug the problem. Remove the 'private' access modifier for the setter methods. 
 
Place the code in  newScoreRuleController () method in a try - catch block and see if it throws an exception. 
Add a system.debug method in the else block to display the contents of MappingRule variable.
 
Let me know the outcome of these steps.

Hi successforce,
 
I removed the private from the Set Method. I have tried putting debug statements but it seems to return the right thing in the debug log. However it doesnt prefill the object in the VF Page. :-(
 
Here is my modified code:
 
   public List<MappingRule__c> mappingRule {get; set;}
 
  // Constructor Method
  public newScoreRuleController () {
    // Give me blank lines of my Object
  try {
    	 String op = ApexPages.currentPage().getParameters().get('op');
    if (op!='edit') {
    	MappingRule = new List<MappingRule__c>();
    	for (integer i = 0; i < 4; i++) {
    		MappingRule.add( new MappingRule__c() );
    		System.debug('HERE');
    	}
   }
   else {
         // Prefill it
    	MappingRule = [select rating__c, ScoreVal2__c, ScoreVal1__c, 
    							ScoreOperator2__c, ScoreOperator1__c, RuleSetId__c, 
    							Mapping_Field__c From mappingRule__c n where RuleSetId__c =: getRuleSetId()];		
    
   	 	System.debug('mapping rile: '+ MappingRule);
   // for (MappingRule__c m : MappingRule) {
    // System.debug('Score val1: ' + m.ScoreVal1__c);
   // }
   }
      } catch (Exception ex) {
  	System.debug(ex.getMessage());
  	ApexPages.AddMessage(new ApexPages.Message(ApexPages.Severity.ERROR, 'Query Error: ' + ex.getMessage()));
          //	return null;
  }
    
}
 
 It still doesnt work. :-(

Nice work!
 
it's a bit strange that you had to do it that way, but if it works go with it.
