Back button hangs install

[sagimann]

Hi,
I have an installation that some panels cause the following error in the console when I click their "back" button:

I tried to isolate the problem by copying the "bad" panel to a new project, but I was unable to reproduce the issue there. On the other hand, we already have 2 install projects, written separately (in IA 8.0.1 Enterprise), that have this issue.

The mentioned panels are inside an action group, and the rule on the action group is always true for both the panel and the one before it. This was checked with a simple console output.

Does anyone know how to diagnose this?

Update: I found the cause of this error, at least in my case. And I also found a workaround - but no explanation. This is definitely not a behavior I would expect.
I'm attaching a sample project that works around the issue. I wrote the explanation in the comment (see pre-install section).

tnx

I am having same problem but could not understand your workaround. With your project I removed the 'set variable X=$EMPTY_STRING$' action and build the project but I don't encounter the problem when I ran your install. I think I will understand the workaround better if I can first recreate the problem with your project. Could you please post the sample project where I can recreate the problem.

I really appreciate your help.

Thanks

Well, the project I attached should recreate the issue once the set x=$EMPTY_STRING$ is removed. This is what I saw. If you cannot recreate the issue using this, we should try and compare our build envs. Mine:

Win 2003 R2 SP2 + 8.0.1 Enterprise build 3083
or:
WinXP Pro SP2 + IA 8.0 Enterprise build 3060

I build from cmdline or designer, without any special switches (only what you see in the project itself)

In any case, you say that you are experiencing the issue as well. Could you post a sample project?

thanks...
