Error linking subform when connecting LO Base 7 trough tcp

Error linking subform when connecting LO Base 7 to tcp jdbc database (h2 or hsql)
Always get error when attempting to run a form-subform
error=image description

Same form-subform works fine if I use embedded hsql

@rstp

looking at the error message i can only suggest:

from the ‘Base’ window

‘menu:Edit>Database>Advanced Settings’

hit tab ‘Special Settings’

ensure checkbox is activated for

‘Replace named parameters with ‘?’’

Thanks a lot. I’ve been stumbling on this problem for months. I should have known to ask.
