Is there a way to use some kind of semaphore in ivy?

I have the situation that I have a database call which gives me a list of elements. Some activities later I write down the modified elements to the db. This is working fine als long as I don't have parallelism. The problem is that the second db operation potentially affects the first db operation. If now two tasks arrive at the first element and read from the database before one task has written the result to the db I get a wrong result. The solution would be to prevent the second task entering the first database read until the first task has written down the result.

Do we have some kind of support for such cases?

Error handler redirect to Web Page or User Dialog ?

Stelt0 — Thu, 04 Aug 2016 14:38:50 -0400

Hello All,

I have an interesting situation.

I have a User Dialog with interactions and a bit complex Logic. There is a point in the process where I`m trowing an exception and I want to redirect the user to an error page:

I want to catch the exception in the business process where to do the redirect. Here is the confusing part:

If I redirect to User Dialog, everything is working correctly:
If I redirect to Web Page (JSP from the CMS) it is trowing an error.

Is this a bug or wrong architecture from my side ?

anyway, what is the best practice for managing exceptions in User Dialog`s Logic?

Best Regards, Yordan Yunchov

Hi,

We're facing following situation and would like to know your recommendation:

We generate files (employee worksheets) and want to store them (sometimes there will be different versions of a worksheet). Where would you recommend to store the files? Is there a way to persist them? Or would you store them in a file location or even cms?

Thanks for your recommendation in advance.

Regards, Daniel

Where should I store my data?

Xpert.ivy provides multiple possibilities to manage data. Is there a overview to get a quick overview in which case I should use which 'data store'?
