using variable in setup preference task : possible ? [message #1808105]

Hi,

I'm trying to set up WST instance inside my setup project but i'm facing a problem:

1) I want to leave the user the opportunity to specify the location of a tomcat installation
2) And finally, i want my project installer to automaticaly set the "/instance/org.eclipse.jst.server.tomcat.core/locationorg.eclipse.jst.server.tomcat.runtime.70" preference to the location specified by the user

So in my project setup there is

<?xml version="1.0" encoding="UTF-8"?>
<setup:VariableTask
    xmi:version="2.0"
    xmlns:xmi="http://www.omg.org/XMI"
    xmlns:setup="http://www.eclipse.org/oomph/setup/1.0"
    id="tomcat.base"
    type="FOLDER"
    name="tomcat.base"
    label="Répertoire d'installation tomcat">
  <description>Répertoire d'installation tomcat</description>
</setup:VariableTask>

then..

<?xml version="1.0" encoding="UTF-8"?>
<setup:PreferenceTask
    xmi:version="2.0"
    xmlns:xmi="http://www.omg.org/XMI"
    xmlns:setup="http://www.eclipse.org/oomph/setup/1.0"
    key="/instance/org.eclipse.jst.server.tomcat.core/locationorg.eclipse.jst.server.tomcat.runtime.70"
    value="${tomcat.base}"/>

But it doesn't works....

The installer asks the user for a tomcat location, at the end of the installation, I got an eclipse , with a tomcat Server runtime environment, but with an empty tomcat installation directory.

It seems that preference
"/instance/org.eclipse.jst.server.tomcat.core/locationorg.eclipse.jst.server.tomcat.runtime.70" has not been set

Question :is the use of variable allowed inside preference setup task ?

Regards..

I don't know if giving the variable task an id is a problem. It shouldn't be, but it's also pointless.

If you, in that installation, do Help -> Perform Setup Tasks and on the Confirmation page, check Show all triggered tasks. Do you see your preference task there? If you select it, you can see its properties. Do they look as you would expect, i.e., using the expanded variable's value? Are you sure this is the right key for the preference you're trying to set?

I did a new try but before I took care to suppress all relative tomcat datas in my user.setup.

On installation process, installer asked me for tomcat installation location.

Once the installation over, I get a recorded tomcat installation but without installation directory:

the "Help -> Perform Setup Tasks" shows nothing about prerefrence setup:

[EDIT] : however, installation log shows that preference is well set...

Weird....

As I mentioned already, on the Confirmation page there is a check box at the bottom of the page labeled "Show all triggered tasks". You should see your preference task if you check that.

Also try removing the id from your variable task; that could cause a problem because variables are synthesized for tasks with an id and given this id has the same name as your variable's name, that might cause a problem.

Sorry to forgot to check the right checkbox. Below a screenshot :

Removing the id from the variable task fixed the problem : Thank you for your precious help

Yes, I had a feeling that might be a problem. We really should fix that, i.e., not generate variables from variables with an id, so I opened the following:
