Sporadic error :Variable not defined

[dbindernagel]

Hi,

we have the following problem:
(Version: PVSS V3.9)

- Sometimes part of an object based on the stdLib is not visible.
- The problem appears only sporadically. We have found no way to reproduce it. Changing the panel does solve the problem for the moment.
- This happens only on some clients (seems to be always the same clients, but not 100% sure).
- The log states that the variable "shapeForm" (defined in scopeLib in objects\\symbols_enum\\stdlib_enumObject_1.pnl) is not defined.
- The variable is normally written to inside the Initialize script of the "stdlib_enumObject_1.pnl" panel.
- Since the variable "shapeform" has no correct value (because of the error) the function "panelSetVisibility" (also inside scopeLib of stdlib_enumObject_1.pnl but called from somewhere out of the stdLib) does not set the correct shape visible.
- The object stdlib_enumObject_1.pnl has not been modified.
- The variable not defined error also appears for other objects.

Since this does seem to happen only on some clients I suspect the problems with the clients but I can't find any problems.
I also don't see how this could happen at all. The variable inside the scopeLib should always be defined.

Does anyone have an idea what could be the problem or hints how to troubleshoot this problem?
The "Assignment to this expression impossible" error also comes right before the "Variable not defined" error, but I'm not sure this is always the case, but it seems like it looking through the logs.

Does your panel use removeSymbol() ? We once had an issue with that showing similar errors - although with a newer version.
Do you see other errors in the log from the UI ?

[dbindernagel]

The panel does not use "removeSymbol()" but it could be possible that other panels that are visible on the screen at the same time use this function.

I looked into old log files and apparently the problem is not new.

We currently do have other error messages with the client but in the log I found an old entry with the UI being started and the next entries being the error messages.
If I upload a file is it visible to everyone or just ETM? I could upload the complete log file if that would help.

I had a look at the panel code.
The variable is defined in the ScopeLib and it is used in the Initialize script of the panel.

At the object "symbol_rect" I cannot see a Initialize script.
The only Initialize script is defined for the panel.

Are you using a modified panel with an Initialize script at the object?

No, the panel only exists in the stdlib folder and is not in any of our libraries or the project.
I also verified that there is no script at the object "symbol_rect". The Initialize is only on the panel.

I then performed a quick test on my notebook and inserted an error in the Initialize script of the panel (with 3.14, but should not make a difference) and the error message in the log also mentions symbol_rect.
