How to get value of Custom Attributes in RTC extensions ? a simple example of text field can help me.
![]()
I'm writing RTC extensions for customized email rules. For sending an email to the owner I can't use the Owner built-in field. I need to use my own custom field(This is a requirement). I don't know how to read the custom field. I thought it would be easy like
String assigned_developer = workItem.getAttribute("assigned.developer").getValue(); where assigned.developer is the Id of the custom attribute. Using the samples from the forum below code snippet I get Null pointer exception: I'm using this in Process advisor Sample code(which is working fine). The exception is in the first for(){} IAuditableCommon iac = saveParameter.getSaveOperationParameter().getAuditableCommon(); @SuppressWarnings("deprecation") IWorkItemCommon workItemCommon = iac.getPeer(IWorkItemCommon.class); //shows deprecated //List<IAttributeHandle> wi_attribs = workItem.getCustomAttributes(); for(IAttribute ia:workItemCommon.findAttributes(saveParameter.getOldProcessArea().getProjectArea(), monitor) ) // this is where I get null pointer exception { System.out.println("\n For started 4444444! \n "); if(workItem.hasAttribute(ia)) { System.out.println("processing for variable="+ia.getDisplayName()+" attrib type="+ia.getAttributeType()); try { System.out.println("\n TRy started here!! \n "); // this will throw exception if not enumeration IEnumeration<ILiteral> enumeration = (IEnumeration<ILiteral>)workItemCommon.resolveEnumeration(ia, monitor); if(enumeration!=null) { String[] iaval = ia.getValue(iac, workItem, monitor).toString().split(":"); if(iaval.length>1 && iaval[1]!=null) { List<ILiteral> enumerationLiterals = enumeration.getEnumerationLiterals(); for (ILiteral literal : enumerationLiterals) { System.out.println("\n Second For here!! \n "); if(literal.getIdentifier2().getStringIdentifier().equalsIgnoreCase(iaval[1])) { System.out.println("attribute name="+ia.getIdentifier() +", type"+"="+ia.getAttributeType()+" literal="+literal.getIdentifier2().getStringIdentifier()+" literal name="+literal.getName()); break; } } } } } catch (Exception e) { System.out.println("\n This is from CATCH started here!! \n "); System.out.println("Exception="+e.toString()); } } } Any help would be highly appreciated. |

Hi Ralph,
forgot to mention in the above code snippet

Anup, using the common API is a good move. I have to confess, sometimes it is hard to find the sweet spot.
