Form lost?

[t4nu]

Hi,
Lately I experience a weird problem, several form that has been done, suddenly lost, so the link to that page from other location trigger the error.
I suspect if this is something to do with the number of pages in a form, is there any limitation to how many pages in a form?
In my form there is not too many pages, just around 40 pages.
Or maybe it caused by other things. Anybody experience something like me?
Currently I use Ebase 5.0.1 on windows 10

There are several other problem, but the most annoying is the lost of the form.
The other are, integrated server that shut down stated that there are no connection for too long, the IDE that hang randomly.
I can live with the halt because of the hang and the random shutdown of the integrated server but not with the lost of the form.

Any help would be appreciated.
Thank you in advance for the help.

I'm not sure what you mean by loss of form. Do you have any error messages and/or stack traces in the server log?

There is no limitation on the number of pages per form. I'd be very surprised if this is causing any problems.

You might check if you have an duplicate forms - form names must be unique. You can check this in the Errors Panel in the designer, usually this is in the bottom l-h corner. Also the server issues messages when it starts about duplicate forms.

Regarding hangs in the designer, I recommend you upgrade to V5.1 - quite a few of these problems were fixed in that release.

Hi,
What I mean is the form is no longer exist in the list of tab pages.
So when I click (for e.g.) the menu to access that page, it give me an error like this:

Code: Select all

com.ebasetech.ufs.runtime.events.rhinojavascript.JavascriptExecutionHandler$RhinoScriptException: Can't find method com.ebasetech.ufs.runtime.external.api.impl.WebFormImpl.gotoPage(org.mozilla.javascript.Undefined). (menuScript#33)

I am pretty sure that there is no duplicate, because when I add a new page and change its name, when the name is already exist it will give me an error message.

If I upgrade ebase designer to latest version, while the ebase in the server still using the older version, will it gave a problem?

Thanks for the respond.

I see what you mean - the page doesn't exist. Do you see the page in the designer? If yes, the problem will probably go away when you restart the server.

I would recommend an upgrade to V5.1. You should do both designer and server components if you do this.

[t4nu]

That's the problem. The page is no longer exists in the designer, so when I published the application to update it, that error come up.
I have checked the page list, and seems more than 2 pages are missing.
Fortunately the database resource and the script is still there so all I have to do is recreate the form and link it again to the script.

If I upgrade to the latest version (5.1) will I have to resetting the server again? Especially the tomcat part.

I don't know of any errors that will delete pages - I've never seen this. Are you sure you haven't deleted them? It's a good idea to check your workspace into SVN or some other version control system so you can always go back if something like this happens. There isn't anything in V5.1 that will fix a problem like this. But V5.1 does contain some fixes for designer hangs and sluggish designer behaviour.

If you upgrade, you should upgrade both the server and the designer. Then restart both.

Absolutely sure that I have delete any pages (event I haven't delete any test pages). Yes, seems this is the time for the SVN stuff. Will do it immediately, thanks for the suggestion.

To restart is no problem at all, but if I have to resetting the server, that would be quite troublesome.

I don't know what you mean by "resetting the server". To do the upgrade you will:
1. Stop the server
2. Copy some files from the upgrade package
3. Restart the server

[t4nu]

Is the installer do the copy (upgrade) or I have to do it manually?

You have to do it manually I'm afraid. The upgrade package is just a zip file with instructions.

IC.
OK. Noted.
Thanks.

Yesterday my notebook hang, until I have to pull the battery to shut it down.
When that happened the designer is open. This morning I found out that there are 10 pages in 1 form has been lost.
Could it be the hang until I have to pull the battery be the cause of that lost?

It sounds like you might have disk problems, and that might explain why you've lost the pages. I suggest you do a full disk check. To answer your question, yes your computer could be the cause of your problems.

[t4nu]

as far as the tools I used to check the disk, everything is ok.
I used the standard checkdisk in windows.
