Hi,

I want to initialize some default parameters in sys operation in run time before the UI interface is displayed to the user. Could someone please let me know where and how to pass the contract parameters to set the values?

Thanks!!

RE: How to initialize parameters in sys operations?

The suggestion made by Martin works just fine in standalone customizations.

Yet it may not be applicable to contract extensions, unless the extended base class was implementing SysOperationInitializable. My solution is dumb as a brick: use a default value for the class variable:

[ExtensionOf(ClassStr(AssetRollForwardContract))]
final class EGCAssetRollForwardContract_Extension
{
private boolean calculateDepreciationInfo = true;

...

Surprisingly, it works.

MSandy, I replied to your specific question in your thread Initialize contract parameters for recurrence batch job in SysOperationFramework. Please continue the discussion there if needed.

RE: How to initialize parameters in sys operations?

My code is like this:

[DataContractAttribute, SysOperationAlwaysInitializeAttribute]

public class DataContract implements SysOperationInitializable

{

public void initialize()

{

fromDate = prevQtr(DateTimeUtil::getSystemDate(DateTimeUtil::getUserPreferredTimeZone()));

toDate = DateTimeUtil::getSystemDate(DateTimeUtil::getUserPreferredTimeZone());

}

}

RE: How to initialize parameters in sys operations?

Hello Martijn,

I have a contract class where i am initializing the "from date" and "to Date" by implementing sysOperationInitializable. I decorated my contract class with SysOperationAlwaysInitializeAttribute. when i manually run the batch job, contract taking newly initialized values but when i add this to a Batch Job with recurrence it is not taking the initialized values instead running with the same contract values every time.

could you please help me what is the issue?

Thanks,

Sandeep

Looks like you need to generate incremental CIL to take effect.

RE: How to initialize parameters in sys operations?

If you read my first reply in this thread, you'll see that I mentioned SysOperationInitializable there too and I said that SysOperationAlwaysInitializeAttribute is optional.

There are two steps.

First you need your initialization logic, which is done by implementing SysOperationInitializable.

But it doesn't mean that initialization is called every time. If you run the process for the second time, it will likely use parameters from the previous execution and the initialization will be skipped. If you want to enforce it, SysOperationAlwaysInitializeAttribute will help you.

I have SysOperationInitializable working satisfactorily, I will stick with this until I have more time to understand and figure out why SysOperationAlwaysInitializeAttribute doesn't want to play

RE: How to initialize parameters in sys operations?

Good Morning Martin,

I'm quite new to attributes also.

The below example should have the two parameters always initialized each time the class is called?

It doesn't seem to have made any difference for me. I'm still trying to explore why, but any additional help or advice would be greatly appreciated.

I noticed in another post, you talk about implementing SysOperationInitializable(which I am researching now), but SysOperationAlwaysInitializeAttribute seems like a far better option for my case anyway.

Thanks.

[DataContractAttribute, SysOperationAlwaysInitializeAttribute]

public class SysOperationDataContractClass
{
TransDate dateValue;
Description255 textValue;
}

Aha, I see, you don't know how to use attributes.

To apply an attribute to a class (or "to decorate a class with an attribute"), put the attribute name in [ ] just above the class header in classDeclaration node. For example, this is how you apply DataContractAttribute:

[DataContractAttribute] public class MyContract

In your case, you'll want to apply two attributes:

[DataContractAttribute, SysOperationAlwaysInitializeAttribute] public class MyContract

If you used cross-references on SysOperationAlwaysInitializeAttribute, you would easily find a plenty of example how to use it.

You would extend an attribute class if you're creating a specialized attribute; that's clearly not your intention here.

Yes. I tried by extending SysOperationAlwaysInitializeAttribute class in contract. initialize() doesn't hits.!
