Empty dialog in Ubuntu: Modal Window "Upload These Changes" not usable after "Data with errors, upload anyway"

[oscar@…]

Sometimes (quite often for me) the upload of changes I have done is not possible because the "Upload these changes" dialog has neither text or buttons.

Steps to get this error:

• do some changes in JOSM (with "errors" like unnamed ways)
• upload the changes
• dialog "Data with errors, upload anyway" -> confirm
• empty "Upload these Changes" Dialog appears.

To upload my changes anyway, I try to zoom in, zoom out, move in the editor window. After some of these actions I am able to upload again.

What JOSM version do you use? What version of the validator plugin? What OS?

Replying to anonymous:

What JOSM version do you use? What version of the validator plugin? What OS?

The problem appears with JOSM 757 and validator plugin 8911. The environment includes Sun's Java 1.5 and Ubuntu Linux.

Can you update Java? I fear that is a Java bug and no JOSM bug. Not reproducable here.

I've seen this bug, too. Not in JOSM AFAIR but in soapUI. It looks like the bug filed here:

Can you confirm the setup, oscar? Ubuntu with Compiz desktop effects enabled?

I made a quick test with various JDKs. The problem exists in the currently bundled OpenJdk and Sun Jdk versions from Ubuntu 8.4. There is a new Sun JDK version in the Ubuntu "Proposed Updates" which does not solve the problem.

I then checked the newest RC of the upcoming Sun JDK 6u10. It looks like this version finally fixed the error (as reported in the ​sun bug report 6632124). So you will probably have to wait until Sun finished the release and Ubuntu packages this one or you ​get the latest RC and use it.
