[TYPO3-workspace] Workspace/versioning frontend

[Pierre N.]

Hi folks,

i have a form to create/edit a new model on my page. I have a fe_user coupled with a redactor (simulatebe) who can edit this form.
Im be the redactor can onlit edit in the custom workspace i've created. It works fine, the model is well saved. Im FE, when he edits the model from the form, the model is edited on live workspace (although $GLOBALS['TSFE']->sys_page->versioningWorkspaceId =1 my custom workspace).
How can i achieve that a change in FE is saved in the custom workspace?
I've read about putting the following "$GLOBALS ['TSFE']->sys_page->versionOL ('tx_jobs_domain_model_xx', $xxx); but i only have queries like
$this->xxxxRepository->update($xxx);  or $this->xxxxRepository->add($xxx);
