is there way resolve issue save functionality? form can submitted cannot saved within livecycle html workspace.

this issue resolved changing jboss connector accept data larger 2mb (the default). increasing file size limit, forms large images , / or attachments saved in livecycle workspace. added javascript pdf form calculate size of added attachments , images , limit users exceeding new file size limit.
