[e3.2] POM Editor can't open pom.xml twice

Arnaud, can you please attach Eclipse configuration details from Help / About Eclipse SDK / Configuration Detials?

I have attached my IRAD 7.0.0's configuration details

When I try and open the pom many times, the pom editor open finally but I have synchronisation problems between pom editor and pom.xml.
In the first screenshot I give a name to the project but it isn't reported to pom.xml (second screen) and when I save and close the pom, the modification wasn't save indeed.

I precise when I open a pom.xml for the first time in this workspace session every modification in the pom editor works correctly.

I have the same problem on an eclipse 3.3. The sync problem is specially annoying. If I try to modify values in the Pom editor in the summary tab, I never can save them, I always have the * in the tab indicating unsaved file. These changes are not pushed into the pom.xml tab. If I do the opposite: same behavior, but it seems that what is finally saved is the content of the pom.xml tab.

Samuel, can you please attach your Eclipse configuration and any errors from Eclipse log file from <workspace>/.metadata/.log. Thanks.

Please find here my eclipse config.

New dev build is released that has number of fixes in the pom editor. It can be installed from the dev update site at http://m2eclipse.sonatype.org/update-dev/
Can you please test this issue with this build and report if is is still present. Thanks

I have test with the new dev version and pom editor's still not working correctly but comportment and exceptions are new.

The first opening everything is ok.

The second opening I have this Error log :

When opening the pom after write someting in the overview tab and close (producing the "Can't update view" error), I return in the third-opening state.

When I close and reopen the pom without write someting, I return in the second-opening state.

Arnaud, thanks for the update. Can you please attach your Eclipse configuration after the update?

Reproduced on clean eclipse 3.2.2 install + wst 1.5.4 + latest dev build (0.9.6)

3.3.2 and 3.4 stream builds are ok... The problem is with underlying wst persistence layer

Samuel, you have 3.3.2-based config. Do you still have the problem with latest dev build?

My eclipse is 3.3.2 based, and I this issue seems fixed in latest build.

Please find here my IRAD conf.

Have to postpone

Opening twice a pom with the pom editor I get an exception. It is very annoying because to make things working I have to restart Eclipse.
I'll attach screenshots and eclipse configuration details.

This is my eclipse configuration details.

This is an eclipse log fragment showing the exception that occurs when I open twice a pom.xml file.

Opening twice the same pom, here the result!!

Sergio, this issue only specific to Eclipse 3.2. Is there any particular reason you can't update to more recent Eclipse version? From your Eclipse configuration it doesn't seem like you have any version-specific features installed.

Eugene, no I can't upgrade Eclipse because I'm using some company plugins that require eclipse 3.2.

Sergio, I use version 0.9.5 without "org.maven.ide.eclipse.editor.feature" optional plugin. It works perfectly on eclipse 3.2.
The next versions (0.9.6, ...) cause sync problems, not only in POM Editor but in whole workspace.

I wonder if it is possible to maintain a branch based on version 0.9.5, in order to support eclipse 3.2.

Arnaud, this particular issue has nothing to do with synchronization.
Also, have you tried 0.9.7 dev build? We have made some fixes that supposed to address issues with JDT support in 3.2. You can use update site at http://m2eclipse.sonatype.org/update-dev/

Ok, the last dev build (0.9.7.200810211352) works better than version 0.9.6, on an up to date version of eclipse 3.2 (I join a new configuration details file).
But I notice a bug :

Salut Arnaud,

can you please open a new JIRA ticket, for this new bug?
We need to change the API used in WTP integration plugin to make it backward compatible w/ eclipse 3.2.
Thanks,

regards,

Fred Bricon

It's done, the ticket is http://jira.codehaus.org/browse/MNGECLIPSE-1064 in WTP Integration component
