Okay, this just blows now that I can’t use eclipse on my faces projects. Was working fine under 6.5, but the ‘new’ stuff consistently throws NPEs, popping up stupid NPE dialogs (which have no important info in them at all).

And these NPE dialogs will keep coming up whenever I try to edit the doc if there are some malformed tags (which, of course there is if you’re in the process of actually trying to edit the tags).

Focus on the edit page is lost, and I just want to throw the monitor through the window.

I’ve tried changing the editor to the xml editor (not the faces editor), disabling all runtime validation, etc. but just can’t get it to drop whatever issue is causing the tlds to throw the NPE exception in the first place.

As the dialog is no help, I have no idea if TLDs need to be added/removed, or what I need to do to fix this problem…

Can you please go to MyEclipse > Installation Summary > Installation Details and paste the information here for me. Also, can you list the steps to help me reproduce this bug at my end.

Thank you.

[dnebinger]

Honestly I don’t know how to recreate. I just know that when I open a .xhtml page, the NPE dialogs start popping up whenever I try editing the page…

Anyway, here’s the installation details…

Do you face this issue with all .xhtml files? Incase you face this issue with certain .xhtml files only, can you paste a sample .xhtml file here for me.

Also, if you switch to a new workspace, create a new project and add the xhtml file to it, does the problem persist?

[dnebinger]

I face this problem with all .xhtml files, but it is sporadic; sometimes I get the NPE, sometimes I don’t. I haven’t been able to figure out what triggers it.

I created a new workspace when I upgraded to 7.0; I can try it again if you think it might point to a problem…

[dnebinger]

Hmm, well a little insight I guess…

My project is ant-based. I’ve got an ant script in the root that creates and uses a build directory when it is building the project. Since I’m building a war, I get temporary class files here, and also build a representative directory structure for the ant war task to construct a war from.

I happened to be looking at the error log to try to find some more info, and I saw a message there indicating that a .tld file was out of sync with the filesystem. Normally my build directory is not part of the project explorer as the ant script, through cleaning, rebuilding, etc., will be constantly making changes to the files in the directory.

It looks like at some point Eclipse refreshed the project explorer view and found the build directory and added it and it’s contents (as it does if you restart eclipse after a recent crash). Since ant had changed many of the files since that refresh, that would explain the ‘out of sync’ message.

I deleted the build directory from the project explorer tree, and now all of a sudden the NPE messages are gone.

[dnebinger]

I’ve verified that somehow the build directory populated by ant from outside of eclipse is causing the NPE dialogs.

The worst part is that eclipse is finding the build directory on it’s own; I do not choose to refresh the project explorer tree, eclipse is doing this on it’s own.

When the NPEs start occurring, I find that I just need to delete the build directory from the project explorer tree and all is fine again…

But it still sucks to have to go through this…
