I am on Enterprise Architect 13.5, creating a deployment diagram. I am defining our servers as nodes, and using attributes on them so that I can specify their details, such as Disk Controller = RAID 5 or Disks = 4 x 80 GB.
When dragging instances of these nodes onto a diagram, I can select "Set Run State" on them and set values for all attributes I have defined - just like it is done in the deployment diagram in the EAExample project:
Since our design will have several servers using the same configuration, my plan was to use the "initial value" column in the attribute definition on the node to specify the default configuration so that all instances I create automatically come up with reasonable values, and when the default changes, I would only change the Initial Values on the original node instead of having to go to all instances:
My problem is that even though I define initial values, all instances I create do not show any values when I drag them onto the diagram. Only by setting the Run State on each instance, I can get them to show the values I want:
Is this expected behavior? Btw, I can reproduce the same using classes and instances of them, so this is not merely a deployment diagram issue.
Any ideas are greatly appreciated! I'm also thankful if you can describe a better way to achieve the same result with EA, in case I am doing it wrong.
What you could do is to either write a script to assist with it or even create an add-in to bring in more automation. Scripting is easier to implement but you need to run the script manually (which however can add the values in a batch for newly created diagram objects). Using an add-in could do this on element creation if you hook to EA_OnPostNewElement.
What you need to do is to first get the classifier of the object. Using
Repository.GetElementByID(object.ClassifierID)
will return that. You then can check the attributes of that class and make a list of those with an initial value. Finally you add the run states of the object by assigning object.RunState with a crude string. E.g. for a != 33 it would be
#VAR;Variable=a;Value=33;Op=!=;#ENDVAR;
Just join as many as you need for multiple run states.

When I create a ParametersVariation simulation, the main model does not run. All I see is the default UI with iterations completed and replication. My end goal (as with most people) is to have a model go through a certain number of replications, but nothing is even running. There is limited documentation available on this. Please advise.
This is how Parameters Variation is intended to work. If you're running 1000 runs and multiple replications with parallel runs, how can you see what's happening in Main in each?
Typically, the best way to benefit from such an experiment is to track the results of each run using elements from the Analysis palette or even better to export results to Excel or similar.
To be able to collect data, you need to write your code in Java actions fields with root. to access elements in main (or top-level agent).
Check the example below, where after each run a variable from main is added to a dataset in the Parameters Variation experiment. At the end of 100 runs for example, the dataset will have 100 values of the main variable, with 1 value for each run.
I built a custom CHAID tree in SPSS modeler. I would like to assign the particular terminal nodes to all of the records in the dataset. How would I go about doing this from within the software?
Assuming that you used the regular node called CHAID, if you select inside the diamond icon (created chaid model) in the tab configurations the rule identifyer, the output will add another variable called $RI-XXX that will classify all the records within the terminal nodes. Just check that option and then put a table node after that and all the records will be classified.
You just need to apply the algorithm to whatever data set you need, and you only need to inputs to be the same (type and eventually storage).
The diamond contains the algo and you can disconnect it and connects to whatever you want.

I am using Rundeck for basic API calls periodically or manually. As of now, I have a lot of options the user has to provide, but most of them remains empty.
In fact, some of them depends on a previous one (e.g do you want X ? Then provide Y). Is there a way to display some options only if another has a given value ?
I would like not to create two different jobs but to keep only one.
One possible way is with Cascading Remote Options
This provides a mechanism for declaring hierarchical or dependent sets of option values.
i'm creating some BIRT-Reports with Eclipse. Now i got the following problem.
I've got two datasets (Set one named diag, set two named risk). In my report i produce fpr every data in diag a region with an diag_id. Now i tried to use this diag_id as input parameter for the second dataset (risk). Is this possible, and how is this possible?
To link one dataset to another in BIRT, you can either:
Create a subreport within your report that links one dataset to another via an input parameter - see this Eclipse tutorial.
or:
Create a joint dataset that explicitly links the two datasets together - see the answer to this StackOverflow question.
Alternatively, if both datasets come from the same relational database, you could simply combine the two queries into a single query.
If you are using scripted data sources, you could use variables.
Add a variable through the Eclipse UI called "diag_id".
In the fetch script of diag, set diag_id:
vars["diag_id"] = ...; // store value in Variable.
Then, in the open script of risk, use the diag_id however you need to.
diag_id = vars["diag_id"];
This implies that placement of risk report elements are nested inside the diag repeating element so that diag.fetch will happen before each risk.open.
I have a requirement to allow a user to specify the value of an InArgument / property from a list of valid values (e.g. a combobox). The list of valid values is determined by the value of another InArgument (the value of which will be set by an expression).
For instance, at design time:
User enters a file path into workflow variable FilePath
The DependedUpon InArgument is set to the value of FilePath
The file is queried and a list of valid values is displayed to the user to select the appropriate value (presumably via a custom PropertyValueEditor).
Is this possible?
Considering this is being done at design time, I'd strongly suggest you provide for all this logic within the designer, rather than in the Activity itself.
Design-time logic shouldn't be contained within your Activity. Your Activity should be able to run independent of any designer. Think about it this way...
You sit down and design your workflow using Activities and their designers. Once done, you install/xcopy the workflows to a server somewhere else. When the server loads that Activity prior to executing it, what happens when your design logic executes in CacheMetadata? Either it is skipped using some heuristic to determine that you are not running in design time, or you include extra logic to skip this code when it is unable to locate that file. Either way, why is a server executing this design time code? The answer is that it shouldn't be executing it; that code belongs with the designers.
This is why, if you look at the framework, you'll see that Activities and their designers exist in different assemblies. Your code should be the same way--design-centric code should be delivered in separate assemblies from your Activities, so that you may deliver both to designers, and only the Activity assemblies to your application servers.
When do you want to validate this, at design time or run time?
Design time is limited because the user can use an expression that depends on another variable and you can't read the value from there at design time. You can however look at the expression and possibly deduce an invalid combination that way. In this case you need to add code to the CacheMetadata function.
At run time you can get the actual values and validate them in the Execute function.
