in this line if you don't get any record then you will get this error. convert msa into List<Master_Service_Agreement_Version__c> msaList and first check size if it is msaList.size()>0 the refer first element. It will solve your problem.Thanks.
- Master_Service_Agreement_Version__c msaCopy = msalist.clone(false,true); this line error show that: Method does not exist or incorrect signature: [List<Master_Service_Agreement_Version__c>].clone(Boolean, Boolean) – Ravi Vadher Commented Aug 17, 2015 at 12:35
- i used msalist but did'not solve the issue – Ravi Vadher Commented Aug 17, 2015 at 12:37
- Master_Service_Agreement_Version__c msaCopy = msalist[0].clone(false,true); try this – Tushar Sharma Commented Aug 17, 2015 at 12:37
- tushar i need your help show new error:-List index out of bounds: 0 – Ravi Vadher Commented Aug 17, 2015 at 12:51
- Please let me know. – Tushar Sharma Commented Aug 17, 2015 at 12:52
{!URLFOR("/apex/CloneVersionwithText", "")}? msaid ={!Master_Service_Agreement_Version__c.Id}
In your button you use msaid variable but in class you are getting id variable. I think if you change this line
it will work just fine. You can test you are getting a correct id with putting a system debug line after msaid line.
UPDATE: DML not allowed
- show error "DML currently not allowed" – Ravi Vadher Commented Aug 18, 2015 at 5:38
- DML operations are not allowed in constructor method. You need to move insert and update out of the constructor. If this code will work only once when you clicked the button you can write a new method and add this method in visualforce page action tag. I've updated my answer to make this change. – tugce Commented Aug 18, 2015 at 6:41

System.SObjectException: SObject row was retrieved via SOQL without querying the requested field:
I have a custom object called Technology__c and join object called AccountTechnologies which is a join object between Account and Technology__c .So AccountTechnologies has a master detail relationship from both sides. I have added a count__c roll-up summary field in the Technology__c to get the count But when i access it in the visual force page I get the following error
The following is the visualforce page code
- visualforce
- Are you using the standard controller for the Visualforce page or a custom controller (or extension)? – Matt K Commented Jan 25, 2012 at 14:57
You'll need to add the Count__c field to your query in your custom controller.
If you're querying off of Technologies, the query would look like this: [Select Id, Name, Count__c From Technology__c];
If you're querying off of a junction object, you would need to query the relationship using a subquery. You can check the Technology or AccountTechnologies object definition (App Setup > Create > Objects) and click the Master-Detail field to find the Child Relationship Name. Add an __r to that relationship name to find what object to subquery from.
To get the Technology__r values into another object you would use the getSObjects() method on the Account. This documentation has a great example at the bottom.
Also, check the custom controller documentation for more information.
- but it is column and the Technology keeps changing. how to pass that to a customcontroller so that it can be seen in VF – yatish mehta Commented Jan 25, 2012 at 15:15
- The var t needs to passed to the method in the controller and then be returned to VF to display the count. i dont know how to pass the param t to the controller and process it so that the value is shown in the column – yatish mehta Commented Jan 25, 2012 at 15:21
- how do i pass var t to the controller ..sorry i am a newbie in salesforce – yatish mehta Commented Jan 25, 2012 at 15:39
- I edited the answer above adding a description of how to sub-query for the Technology object from Account. Between the Custom Controller documentation and the dynamic SOQL documentation, you should be all set. – Matt K Commented Jan 25, 2012 at 15:41
- Var t is set by the <apex:pageblocktable> it doesn't need to be passed. It's a single instance of (or one record from) Technologies . – Matt K Commented Jan 25, 2012 at 15:43

If the query doesn't return any rows you will get the "List has no rows for assignment to SObject" exception. Instead, assign the results to a list of sObjects and check the size of the list. Then only use the first record in the list if it is present.
So, in my Visualforce page I call a method "notifyPatients" in my extension "myExtension". The extension class looks like this: public with sharing class myExtension { public Disease__c d {get; set;} public myExtension(ApexPages.StandardController controller){ d = (Disease__c) controller.getRecord(); } } public void notify() { emailHandler ...
What's not obvious is that it also assumes that exactly one row is returned! Although this is unlikely to occur for Contact, it is highly likely to occur for any custom objects you create, especially when a WHERE statement is used that might return zero rows, such as:
Impossible. If you're getting "list has no rows to assign to sObject" it means you're assigning to single object. This eliminates getProductsLov(unless you didn't post whole code) because there you assign to a list.. Humo(u)r me and System.debug(JSON.serializePretty(ApexPages.currentPage().getParameters())); in your constructor before firing that query...
The cure to this particular problem is to ensure that your queries are executing in list mode, i.e., assigning directly to a List<sObject> variable or passing them to a method that takes a List<sObject>, like List.addAll(). In that case, you receive no exception when there is not a responsive object, just an empty list, and you don't run the ...
This issue can also occur when the user attempts to reconfigure a Primary Quote without Read access to the associated Opportunity. Lack of access to the Opportunity object throws List has no rows for assignment to SObject' since our code queries for the Primary Quote on that opportunity.

This is resulting in no records being returned and Salesforce throwing the System.QueryException: List has no rows for assignment to SObject.

List has no rows for assignment to SObject although query returns rows. I am trying to display a selectList in a visualforce page using a custom controller i built.
For some reason, when testing the Screen flow, The apex controller throws a List has no rows for assignment error, when executing the query. The thing is, I logged the Id in the controller to see if it was being passed correctly, and it was, according to the logs: The Id matches what the flow debugger tells me of the created record.

Not really answering the question, but still. You don't have to query for the record based on a GET parameter. If you create a page with a standard controller and an extension, the constructor of the extension gets the standard controller as a parameter. You can use that to reference the record that is loaded.

You'll need to add the Count__c field to your query in your custom controller.-- Edit --If you're querying off of Technologies, the query would look like this: [Select Id, Name, Count__c From Technology__c]; If you're querying off of a junction object, you would need to query the relationship using a subquery.
