could you post me a simple example (code snipped) please, how to create a visualforce page with an input-field (text) and a "submit"-button.
After inserting text in the textbox and click on the submit button, the text should call a apex-class (java) and simlpy append the string "_abc" to the text.
The new text should appear on the visualforce page under the submit button.
I want to loop through all field names and compare the values of a lineitem object...
Heres my not working code:
trigger HistoryOpportunityLineItemV001_test on OpportunityLineItem (after insert, after update, before delete) {
// Get the sObject describe result for the Opportunity object Schema.DescribeSObjectResult r = OpportunityLineItem.sObjectType.getDescribe(); //Generate a Map of the fields Map<String, Schema.SObjectField> M = r.fields.getMap();
//Now loop through the list of Fields for (Object fieldName : M.keySet()){ //system.debug('fieldName: ' + fieldName); if(Trigger.old[0].fieldName.value != Trigger.new[0].FieldName.value) { System.debug('CHANGED fieldName/fieldValue: ' + fieldName + ' / ' + FieldName.value); }
} }
Any ideas?
Thx,
jup

I want to create a trigger that fires after an opportunity will be updated.
First the trigger has to check, if specified fields in the opportunity has changed. If so, the trigger has to log this changes into a new simple custom object (text only).
I wrote my code and the first part works very well:
trigger HistoryOpportunityV001_test on Opportunity (after update) {
// no bulk processing; will only run from the UI
if (Trigger.new.size() == 1) {
String strChanges = '';
//// Checking fields if the value has changed
// 1. Field: Opportunity.Name
if (Trigger.old[0].Name != Trigger.new[0].Name) {
cnt++;
strChanges += cnt + '. <Name>: "' + Trigger.old[0].Name + '" -> "' + Trigger.new[0].Name + '"\n';
}
// 2. Field: Opportunity.Order_ID__c
if (Trigger.old[0].Order_ID__c != Trigger.new[0].Order_ID__c) {
cnt++;
strChanges += cnt + '. <Order_ID__c>: "' + Trigger.old[0].Order_ID__c + '" -> "' + Trigger.new[0].Order_ID__c + '"\n';
}
if (cnt > 0) {
OpportunityLog__c oppLog = new OpportunityLog__c(
OpportunityID__c = Trigger.old[0].Id,
OpportunityName__c = 'oppName',
OpportunityChangesUser__c = UserInfo.getUserId(),
Changes__c = strChanges
);
insert oppLog;
}
}
}
Now I want to implement, that the trigger will check if the value of some specific fields of the updated opportunitys line items (products in the opportuity) has changed. If so, I want to log this lineitems field changes, too.
I know that I have to loop through all line items and have to check the field values.
- BUT HOW CAN I DO THIS?
Could anyone help me, please? It would be great if you post me your code or ideally complete the existing code ;)
Next... I want to log if the user adds a new product/lineitem or deletes a lineitem.
public class ContactsNextBirthdays {
private final Contact contactObj;
public ContactsNextBirthdays(ApexPages.StandardController controller) {
this.contactObj = (Contact)controller.getSubject();
}
public Contact[] getNextBirthdayContacts() {
String UserId = UserInfo.getUserId(); // UserId des eingeloggten Users holen
Date Now = System.now().date();
Contact[] contactList = [SELECT Id, Name, FirstName, Birthdate, Account.Name FROM Contact WHERE Birthdate > :Now AND OwnerId = :UserId ORDER BY Birthdate];
return contactList;
}
}
I tried a lot of queries, but I received never the result I want :-(
my clame is to clear some specified fields while cloning an
opportunity. It is necessary to clear some fields in the
opportunity-line-items, too.
I want to hide the salesforce opportunity duplicate-button and create a
new one with a scontrol on it.
This works fine:
1. I fetch all fields of the source opportunity from the database. Now I
put this fields into a new opportunity-object (array). The specified affected
fields will be leave blank in this step.
2. This new array will now created in the database as a new opportunity
and the new opportunity-id will be kept in mind. (Opportunity)
3. Now all opportunity line-items from the old (source) opportunity will
be passed through and the line-items will be created in the database with the new
opportunity-id. (OppotunityLineItem)
4. Pt. 3 will be repeated for the opportunitys contact roles. (OpportunityContactRole)
5. This should be repeated like Pt. 3 for the opportunity-partners, too.
But here is the problem: The structure (metadata) of the table OpportunityPartner is looking like
it isn’t allowed to append/create fields/lines or modify/update any fields in
this table. Can anybody help me to clone the opportunity this way and duplicate the opportunity-partners
(create/append them in the table OpportunityPartner)?
Screenshot from metadata of table OpportunityContactRole (create/update
allowed):

trigger HistoryOpportunityLineItemV001_test on OpportunityLineItem (after insert, after update, before delete) {
// Get the sObject describe result for the Opportunity object Schema.DescribeSObjectResult r = OpportunityLineItem.sObjectType.getDescribe(); //Generate a Map of the fields Map<String, Schema.SObjectField> M = r.fields.getMap();
//Now loop through the list of Fields for (Object fieldName : M.keySet()){ //system.debug('fieldName: ' + fieldName); if(Trigger.old[0].fieldName.value != Trigger.new[0].FieldName.value) { System.debug('CHANGED fieldName/fieldValue: ' + fieldName + ' / ' + FieldName.value); }
} }
Any ideas?

I have written one after update trigger on Opportunity standard object, which will update one field in Contact Object. But this trigger is getting fired twice.
Any idea on why the trigger is getting fired twice and how to resolve the problem?
