Hello,

I have installed the Hibernate Eclipse plugin, and I have a strange problem with the auto-complete feature of the XML editor - it sometimes offers auto-complete for class properties and hibernate attribute values, and sometimes it does not.

I know this is not a very concrete problem report, but I have been playing with this for a couple of hours now, and I have not been able to pinpoint the problem any better.

It works part of the time - so I know it's installed and enabled. I also tried running eclipe with -clean (I saw this was suggested in another similar post in this forum). For example, it can work for a certain file once, but not again. I have noticed that the first time I open the file in the editor it will work, but not in subsequent times. If I restart eclipes it seems to work, but again, just for the first time.

I am sorry for this lame problem description, but that the most sense I can make of this issue...

My environment:

- Eclipse 3.1.2
- Hibernate plugin version 3.1.0 beta 2.
- WTP 1.0
- Spring IDE 1.2.5
- Oracle 10g
- Hibernate 3.0.4

Any help will be appreciated.

Ah, and last but not least - apart from this small issue, the plugin is really great. Especially the code and mapping generation.

if it does not code complete at some place you expect it then show me the xml and put a * or some other mark where you tried to do the code completion.

then i can tell you if it should work or maybe why it does not work.

In the following XML file I place the cursor on the name of the id field, and also on the type (I inserted a * just to show you where).

When I pressed ctrl+ space, I got the auto-complete. I then closed the file and opened it again in the editor. I tried a second time - and it worked again. I closed the file and opened it a third time - it did not offer me the auto-complete. And it didn't matter even if I tried re-opening the file again and again. I then restarted Eclipse. I opened the file and it worked for the first time. I then closed the file and opened it again - and it didn't work.

The file is in the src folder of my project, and it is exactly as the generator created it. I did not change anything.

Thanks again for your effort. I realise this kind of problems are relatively hard to analyze.

hmm ...looks like a wtp bug.

i have just been using the completion extensively during a training and that worked flawlessly....

May I ask what WTP version are you using?

Thanks

FYI, I have updated my WTP to the latest available from the update-site, and the problem remains.

don't use wtp 1.5 - use wtp 1.0, the one that comes with the tools should work.

Hi,

The auto-completion for Java class properties works now. I guess updating WTP did the trick. Thanks!

However, database table and column auto-completio still doesn't work.

In the "Hibernate Configurations" view I can see the database schema properly, but I don't get auto-copmletion in the editor. There is not error in the log - I simply get "content assist not available at the current location"...

In the Hibernate tools doc it says:


However, when I look at my Eclipse project's Properties submenu, there is no "Hibernate Settings" page. What am I missing?

Thanks again for all your help.

hmm - should just be there.

Can you attach a screenshot of the properties view ?

Sure.

How do I include an image to a post?

you insert a img tag that point to some url that has the image.[/img]

Here it is:

hmmm...thats weird!

Are you 100% sure you have the correct version installed ?

And try and go look in org.hibernate.eclipse.console-x.x.x/plugin.xml and tell me if you have something like:

<extension
point="org.eclipse.ui.propertyPages">
<page
class="org.hibernate.eclipse.console.properties.HibernatePropertyPage"
id="org.hibernate.eclipse.console.properties.HibernatePropertyPage"
name="Hibernate Settings"
objectClass="org.eclipse.jdt.core.IJavaProject">
</page>
</extension>

in there. This is the extension point that should register a property page on every javaproject.

hmm...maybe you need to force the start of the plugin by going to the hibernate console perspective ? try that too and tell me if it shows up or not.

Here is the relevant section from my plugin-xml file.
I think it is the same as your excerpt.




You can review my eclipse env. in one of the above posts. The only thing changed since then is that I upgraded the Hibernate Tools to beta5, and installed the latest patch of the WTP 1.0 (a small version, maybe even a nightly build...).

I did try to go to the Hibernate Console perspective , but that doesn't help. Neither does restarting eclipse, or creating a brand new project.

Seems I manage to stumble on every possible misfortune with this installation :-)
