Preselected JPA Platform and Implementation on JPA Facet page? [message #817067]

Hi,

What is the logic for the Preselected JPA Platform and Implementation on JPA Facet page?

We get our own "default" JPA Platform preselected on Eclipse 3.6 and 3.7 but the "Generic 2.0" on 4.2. We are not sure if it is random or deterministic.

Also for JPA Implementation it seems that if runtime target is selected it would be Library Provided by Target Runtime, otherwise it would be Disable Library Configuration. It is very logical. However it seems that the next time the wizard is lauched the previous JPA Platform and Implementation gets preselected regardless of the runtime. The last setting is stored in <workspace>\.metadata\plugins\.plugins\org.eclipse.wst.common.project.facet.core\prefs.xml

Do we get the existing logic correct? If so it seems a bit unconventional. If a user create a JPA project without target runtime then one with a runtime, he may unknowingly have the project with Diable Library Configuration and missing the runtime library.

Thanks.

Is this all with a clean workspace? I don't believe the logic has changed. There may however be interactions with user preferences. If a user has made a selection before, and that selection is available, it is preselected.

As far as runtime library configuration, we find that many users do not use a runtime-provided JPA implementation. Many use either a user library or plugins for their library configuration. At any rate, the same logic applies. If an available selection was chosen the last time, it is preselected.

Thanks for confirming it is preselecing the previous JPA Platform and Implementation

In a clean workspace though, "Generic 2.0" is preselected even we have "default" platforms defined like:
<extension point="org.eclipse.jpt.jpa.core.jpaPlatforms">
<jpaPlatform
id="myPlatform"
label="%MyPlatformLabel1_0"
default="true"
factoryClass="org.eclipse.jpt.jpa.core.internal.GenericJpaPlatformFactory"
jpaFacetVersion="1.0">
</jpaPlatform>

<jpaPlatform
id="myPlatform_jpa2_0"
label="%MyPlatformLabel2_0"
default="true"
factoryClass="org.eclipse.jpt.jpa.core.internal.jpa2.Generic2_0JpaPlatformFactory"
jpaFacetVersion="2.0">
</jpaPlatform>
</extension>

In Eclipse 3.7 and below our default platform is preselected. Is "default" still honoured in Juno? Thanks again.

OK, I'm seeing a problem with initializing runtime preferences (which is where default platform settings are applied). I'll investigate and update with a bug or whatever other information is applicable.
