Description:
Strange mistake, when trying connect to any MySQL server from the WorkBench on Mac Os X. It say: 
Connection 'Server' could not be established: No bool value passed for CLIENT_COMPRESS
And nothing helped, even full delete of the app with preferences.

How to repeat:
Start WorkBench 5.2.2a on Mac Os X 10.5.8 and try to connect to any MySQL server even without login@pass

Not repeatable on Linux Ubuntu 64-bit.

Many thanks for writing a bug report.

We are not able to repeat this.

Is the server placed on same machine, same network or is it somewhere outside?

Did you made advanced connection settings?

Something like using SSL or compression protocol?

Well, it seems like it's a problem of using old connections from previous version of WorkBench, because i have two equal connections, one from the previous version and one from the current 5.2.2 and the previous connection doesn't work and give this error.
May be while creating connection in new version you just set this parameter by default and in previous version it wasn't used.
Thanks for quick reply, i'll stay on 5.2.2 =)

What exactly do you mean with previous version?

Previous like Workbench 5.1 or Previous like Workbench 5.2.x.
[11 Aug 2009 9:12] Alex Kudryahsov
Sorry, by previous i mean 5.2.1.

Affects both 5.1 & 5.2 branches. Irrelevant to OS.

fix will be included in 5.1.17

An entry was added to the 5.1.17 changelog:

When trying to connect to a server from MySQL Workbench the following error was generated:

Connection 'Server' could not be established: No bool value passed for CLIENT_COMPRESS

This occurred when using connections created in MySQL Workbench 5.2.1 with 5.2.2.

Still happens on 5.2.4.
I had some version of 5.2 running way back, but don't remember which one..

If you need more info i'd be happy to provide :)
