Java collections in ivyScript

Benedict Groppe — Wed, 24 Feb 2010 09:18:46 -0500

I have multiple lists which I combine into one and then have to remove duplicated entries. This in ivyScript. In Java I would use ArrayList for the lists, copy them into a HashSet to remove the duplicates.

But I thin I cannot use HashSet in ivyScript and as well the casting of ArrayList does not seem to work as expected.

Multi threading in Ivy processes

In Ivy I can parallelize processes (and too User Dialog logic) with a Split element and synchronize them again with the Join element. Does this run in multiple threads?

How can I use arrays in ivyScript

I want to use Java arrays in ivyScript. But if I use myArray[myIndex] then I get an error unexpected token.

So, for example how can I do something like:

File dir = new File("myPath");
File[] fileList = dir.listFiles();

Does a user have a specific role?

Benedict Groppe — Thu, 06 Aug 2009 07:02:04 -0400

I need some insights in the role system of Ivy. I currently check whether a user does have a role by checking whether the current user does have a role with the ID of that role I am interested in. One problem is that I have to hard code the ID's, another problem that the ID's are hard to retrieve and they are different on Designer and Server. Is there a more simple way to find out whether a specific user does have a specific role?

Limit number of same rich dialogs in display

Benedict Groppe — Fri, 17 Jul 2009 04:55:02 -0400

I want to load rich dialogs into a display but I want to allow only one instance for one rich dialog. If a rich dialog is started that is already loaded in the display, then the already loaded rich dialog should be selected. Does anyone have an idea how I can achieve this?

Display NULL values in record set nicely in the RTable

Benedict Groppe — Tue, 28 Apr 2009 09:48:16 -0400

I have a record set from a DB query that I want to use for display in a RTable. Some values can be NULL and the result is that the RTable shows them like java.lang.Object@1234 which is not very useful information for the end user.

How can I make this cell empty for the display?
