Top Level Navigation exception

16 Views

Hello all,

I've written a custom TLN (using the navigation tag libraries).

The TLN works a month now. However I got two exceptions in this time (one regarding the original TLN and one regarding to the custom TLN - some users see default TLN and some custom TLN according to a master rule)

After restart the server the TLN works.

Each TLN is embedded in a different frameworkpage.

Both users are Administrators so I don't think it is a permission issue.

Navigation cache is disabled.

I'm still not sure if this is a Framework Page/Portal Desktop or TLN issue...

Portal is 7.00.17
