Cannot see data set created for tutorial

Forgive me for asking this here, but I can't seem to find an appropriate forum. I am trying to learn Birt 2.5 in Eclipse Galileo. In following the tutorial, after following the instructions for creating the data set and clicking 'Finish', the data set does not appear in the data explorer under Data Sets. Have I not installed correctly?

Hi rmr,

What tutorial are you using? What are the steps you're taking to create your dataSet?

rmr

I am using the tutorial that starts at 
<a class='bbc_url' href='http://www.eclipse.org/birt/phoenix/tutorial/basic/'>BIRT Tutorial</a> 
I have followed it almost to the letter. 
The problem occurs at the page that instructs you to create a Data Set: 
 
<a class='bbc_url' href='http://www.eclipse.org/birt/phoenix/tutorial/basic/basic05.php'>BIRT Tutorial</a> 
 
At the problem occurs where it says: 
 
The data set editor now opens. Let's take a look at the pages within this editor. 
 
The problem is that the data set editor does not open. Furthermore, the data set I should have been creating (Customers) does not appear nested under Data Sets in either the Data Explorer view or the Outline view. 
 
Furthermore, if I close Eclipse at this point (or after returning to the Java perspective), I cannot get back in, even if I attempt to enter Eclipse from the command line with: eclipse -clean. Instead I get a message saying: 
 
Workspace unavailable: Workspace in use or cannot be created, choose a different one. 
 
The only way I can get back into the same workspace is to reboot the computer.

rmr,

That is weird. I have not seen the problem of not being able to re-open BIRT. You may try redownloading BIRT. You're creating a dataSource and everything first, correct?

rmr

Yes, I am creating the Data Source first, according the instructions. It is not Birt that I can't re-open, but Eclipse. As for re-downloading, I already had these problems (both the Data Set not appearing after it was created and the locking up of the workspace) under Eclipse Ganymede with Birt 2.3.2. So I went ahead and downloaded Eclipse Galileo with Birt bundled into it. Same problems recurred. It may be something in my workspace and I shall try again with a clean workspace.

Meanwhile I downloaded the Standalone Birt 2.5 and did NOT have the data set problem. But when I got the the part that describes binding in the tutorial, the binding tab in the properties editor did not display the bindings the tutorial said it would. The CUSTOMERNAME field was not bound to any data set column.

Actually I got past the latter problem. I needed to understand that the data set is bound to the table not to each element in the table.

The problem with Eclipse remains.

rmr,

So, using a clean workspace didn't work either? I have never heard of this issue. Not sure what could be causing it.

Dear Michael,

Thank you for your comments. When I tried using BIRT 2.5 in Eclipse Galileo with a brand new workspace, I had no problem with the tutorial. It works just as it does with the standalone version of the BIRT 2.5 RCP. The only question I have now is why my old workspace, which has all our Java, Ant, and other development, cannot be cleaned sufficiently to allow us to use the report designer there as well. I can anticipate some development integration difficulties in the near future.

Richard,

Like I said before, I have never heard of anything like this happening. Maybe you could try moving items over from your old workspace into the new workspace and see if you run into the same problem. This might help you narrow down what is causing the issue. I'll ask around a little and see if I can find anyone who has seen this or has an idea of what could be causing it. I'll let you know if I find anything out.

I have had this problem once in the past with an Eclipse workspace that I used for Java development (No BIRT Projects). What I had to do was create a new workspace, and then I used the the Eclipse Import feature to pull all my projects into the new workspace (File -> Import -> Existing projects into Workspace -> Select root of your old workspace -> Copy projects into workspace)

Not sure if this will solve your problem, but I hope this help.

I am sure that copying existing projects into the new workspace would work but it may not be necessary.
After I got my report working in the new workspace, I went back to the old workspace, where I had already defined a project over the same folder. I did a refresh to bring in the changes that I had made in the new workspace. After that I was able to edit the report in the old workspace and no longer had the problem of the workspace locking up.

Good to hear! Let us know whenever you have questions.
