Can't update manage package Page Layout

[kbabintsev]

Hi. I'm trying to update Layout:

    MetadataService.MetadataPort service = new MetadataService.MetadataPort();
    service.SessionHeader = new MetadataService.SessionHeader_element();
    service.SessionHeader.sessionId = sessionId;
    service.endpoint_x = endpoint;

    MetadataService.Layout layout = 
        (MetadataService.Layout)service.readMetadata('Layout', 
            new String[] { 'CaAwsCloudTrailEvent__c-AWS CloudTrail Event Layout' }).getRecords()[0];

    System.debug(layout.fullName);

    handleSaveResults(
        service.updateMetadata(
            new MetadataService.Metadata[] { layout })[0]);        

    System.debug('DONE');

but getting error "Required field is missing: fullName", because retrieved field fullName is null. It is possible update MP page layout through metadata api? Thank you.

Yes it is possible to do this https://github.com/financialforcedev/apex-mdapi/blob/master/apex-mdapi/src/classes/MetadataServiceExamples.cls#L696. What i have noticed is that for some reason if you get the layout name wrong it returns a blank layout. So double check your layout name via listMetadata or using the Salesforce Developer Workbench tool which also has a means to list metadata.

Yes, name was wrong. Valid name is 'CA10__CaAwsCloudTrailEvent__c-AWS CloudTrail Event Layout' (CA10 is our namespace). But I get the same error. I tried to do this with Java API v29 (http://www.salesforce.com/us/developer/docs/api_meta/), but I got the same result. Everything works well with dev org (where name is 'CaAwsCloudTrailEvent__c-AWS CloudTrail Event Layout').

I see so it works if you try to edit a unmanaged layout, but if you try to edit a managed package installed layout it fails? Is CA10 your managed package namespace?

[kbabintsev]

Yes, that's right. Yes, "CA10" is our namespace.

I'm wondering if this is restriction of the Metadata API, have you tried API v30.0?

[kbabintsev]

v29 is latest version available in maven central http://mvnrepository.com/artifact/com.force.api/force-metadata-api

[kbabintsev]

I solved this. It works if I try 'CA10__CaAwsCloudTrailEvent__c-CA10__AWS CloudTrail Event Layout'. btw listMetadata returns 'CA10__CaAwsCloudTrailEvent__c-AWS CloudTrail Event Layout' (without prefix).

Wow that is inconsistant, glad you sorted it! Enjoy the API now! 👍

Thanks kbabintsev, your solution worked even in v39.
