Description
NS Gopikrishnan
Can you give us some more information about the problem: - the build date of Vex - a stacktrace from the error log - What kind of changes do you do? (In reply to comment #0) > Build Identifier: M20100211-1343 > > This error pops up after we edit the document and try to save it. Due to this > error I am not able to save the document. > > As a part of our documentation tool we are planning to use vex in our > organization. It will be a great help if you are able to help us with > developing VEX. > > Reproducible: Always > > Steps to Reproduce: > 1.Open some XML (DITA, DocBook or any custom DTDs) > 2.Make some changes in the View > 3.Try saving the XML. (Ctrl+S or File->Save) I am able to build VEX from source. But when I run that in a new instance of eclipse, VEX is not loading any document. It doesn't show any dialog to select the document type, And also, it shows only : "Loading" in the Document area. No further progress after that. I got this error message with the VEX build that I obtained from the incubator continuous builds. The kind of changes I do : "Simple text editing like adding a word, Deleting etc..." *Following is the stacktrace: eclipse.buildId=unknown java.version=1.6.0_20 java.vendor=Sun Microsystems Inc.

problem is reproducable? Created attachment 173399 [details]
This is a sample docbook XML.
This is a sample docbook (XML. The XML was properly formatted in the view according to the CSS.)
(In reply to comment #4) Thanks, I can reproduce the problem now. I'll have a look at it tonight (CEST). The document defines a namespace in the root element and the attribute "xmlns" is not defined in the DTD. XML namespaces are not supported yet (see bug 253753). It is not possible to enter undefined attributes, but Vex should be able to handle documents that contain undefined attributes. The validator uses a default AttributeDefinition in this case. The fix is available with the current CI build. Change reviewed: +1 (no comment) NS Gopikrishnan, thx for reporting. Florian, wow, you are really fast! :-)) (In reply to comment #8) > Change reviewed: +1 (no comment) > NS Gopikrishnan, thx for reporting. > Florian, wow, you are really fast! :-)) Thanks Florian :) Yes you are fast !!! I would like to contribute to VEX, Can you people help me with setting up the workspace and dependencies ? (Sorry that I am unable to find a mailing list specific to this project, Else I would have posted this there) Moved to Mylyn Docs Vex. |
