Multiple menu bars and fields

[jayarathina]

I installed UniTime. But i am getting multiple menu bars during login (ten to be exact). The footer also has the Version 4.4.114 built on Tue, 25 Jun 2019 to 10 times.

Some sections of the page (after loging) in also repeats itself.

Some fields inside also replicates itself. (see date field in the below image)

What could be the reason?

[jayarathina]

I am using 64 bit Windows 10 Pro with following config: MySql Server 5.7 (i did not install the latest version because this issue. But i will post about it when i am able to replicate it again. I went the because of this and this) Tomcat 8.5 Java SDK 12.0.2

Log file (if needed) (from Tomcat 8.5\logs)

[tomas-muller]

Such an error has not been reported to us before. I do not see any issues in the log.

What browser are you using? Do you see the same error when you open the online demo? Are you able to reproduce the problem in other browsers?

[jayarathina]

What browser are you using?

Chrome 75.0.3770.142

Do you see the same error when you open the online demo?

No. The Online demo is working perfectly.

Are you able to reproduce the problem in other browsers?

Yes. In all browser installed in my system (Opera and Edge), the same error is there. (I tried freshly installed browser and again with all extensions disabled in chrome, the error persists)

This is a screen shot of the chrome browser log is below, Full Chrome Browser Log is here.

WARNING: Uncaught exception: TypeError: $wnd.unitime.runAsyncCallback7 is not a function
java.lang.NullPointerException: TypeError: $wnd.unitime.runAsyncCallback7 is not a function
    at Unknown.anonymous(http://localhost:8080/UniTime/unitime/deferredjs/B1C2752189CADF72E324D3918459ECAC/7.cache.js)

Is that of any help?

Is it possible that I deployed it wrongly? (copied some files multiple times?) How to remove UniTime alone and deploy it again? What are the files that I need to delete?

[tomas-muller]

I am not able to reproduce the issue using JDK 12.0.2 and Apache Tomcat 8.5.43 in either Chrome 75.0.3770.142 or Firefox 68.0.1. I have tried both the official released UniTime 4.4.114 and the latest nightly build UniTime 4.4.117 that is currently used in the online demo. But I have a Mac. While most of our production installations (that we have worked closely with in the past) are using Linux-based machines, we have some Windows installations as well which as far as I know are working fine.

The TypeError error is in the GWT client-side JavaScript code that is produced by the GWT compiler from Java code. This makes it hard to debug or understand, especially since about 20 different permutations are being compiled (one for each supported browser and locale).

Are you using the official build of UniTime (downloaded from our nightly builds page, GitHub releases, or SourceForge releases) or did you build UniTime yourself?

UniTime can be redeployed by placing a new UniTime.war file in Tomcat\webapps (where Tomcat is something like C:\Program Files\Apache Software Foundation\Tomcat 8.5 on Windows). To ensure that any of the cached files are not reused, could you please try to: 1) stop the Apache Tomcat 2) in Tomcat\webapps, remove the UniTime folder and replace the existing UniTime.war with the new one 3) delete the content of Tomcat\work folder 4) start the Apache Tomcat

[jayarathina]

Are you using the official build of UniTime (downloaded from our nightly builds page, GitHub releases, or SourceForge releases) or did you build UniTime yourself?

I am using the official build of UniTime I downloaded from github. I tried 4.4.117 official nightly build, but same multiple menu problem persists.

Surprisingly I tried with UniTime 4.0 (no longer supported) version (Version 4.0.49 built on Wed, 24 Feb 2016) at https://builds.unitime.org/ and it worked very well.... :smile: :confetti_ball: I don't know why.:confused: Is it ok to continue to use it? Are there any serious bug or holes that I should be aware of? (any major changes that are not in current documentation?)

Is there anything else I can do to help you debug 4.4.114 and make it work in my system?

P.S: May I also ask, which is the oldest release of UniTime (if any) that can generate timetable with classes to availability of professors (i.e., no room constraints)?

[tomas-muller]

UniTime 4.0 is using an older version of GWT (2.7.0, same as UniTime 4.1 and 4.2). Later versions use GWT 2.8.2. I am not aware of any serious bug/holes, but there have been some issues with the older versions of GWT on newer browsers or when deploying older versions of UniTime on a newer version of Apache Tomcat.

There have not been many changes in course timetabling since 4.0 except the solver pages having a newer look and a few additional features and some additional constraints in the solver. The page documentation for UniTime 4.0 is available at http://help40.unitime.org.

The course timetabling solver considers instructors and their preferences and requirements from the start. It is possible to ignore room constraints.

The ability to assign instructors to classes (instructor scheduling) has been added in UniTime 4.2.

[jayarathina]

Is it possible to update the UniTime eclipse help page with the latest details? I was trying to install the latest code, but got error, probably because i was using GWT 2.7.0 as specified in the help page. Is there anything else that has changed? It would be helpful if you could please update the screenshots there as well, as eclipse GUI has changed too (some options mentioned in the help page are not found). If i can successfully compile and run it, then i will try to debug this multiple-menu-problem in my system.

(PS: i closed the issue by mistake, sorry)

[tomas-muller]

You need to use the same GWT version as is used in the version of UniTime you are working with. Otherwise, the setup is the same (except, you may need a newer version of eclipse, Apache Tomcat, etc.).

Please note that you do not need Eclipse to check out and build UniTime. See Building UniTime for more details.

[jayarathina]

I have some question regarding the usage of UniTime (how to do certain things, like changing the start time of the time grid etc.,) where can I ask them?

[tomas-muller]

You can send your questions directly to us using the support@unitime.org email, or post them on the unitime-discuss forum.

[jayarathina]

unitime-discuss link forum says:

This group either doesn't exist, or you don't have permission to access it. If you're sure this group exists, contact the Owner of the group and ask them to give you access.

Can you please check it out? or do you need to add my email address to the forum so that I can ask question?

[tomas-muller]

Can you please check it out? or do you need to add my email address to the forum so that I can ask question?

Please try again.

[jakobvj]

@tomas-muller I just want to notice that I get the exact same issue with multiple items/menu/links etc Followed the installation guide on a Windows Server Tomcat 8.5 MySql Server 8

[tomas-muller]

I have still not been able to reproduce this problem. So far, it has only been reported on Windows and only with UniTime 4.4. I was told that UniTime 4.3 is working fine despite the same version of the GWT library (which is responsible for the menus etc.).

[jakobvj]

Yes, it do work with 4.3 :-)

[tomas-muller]

This problem should be fixed in UniTime 4.4.130 or later.
