I had to add a form to the Sib file, can't be done in the editor.
So generated a sil from existing Sib and added the form manually.
Then exported back to a Sib file. When I try to load the sib file in my program start up an error occurs. "language name shall be included in the Langnames property".
There are several sib files loaded depending on the license therefore the SIB languagues are loaded on the fly.
the default in the dispatcher is Language N1, the languages are loaded runtime. This has never been an issue. If I export the sib to another format then back to Sib without changes, the same problem arises.
Please try the following in SIl Editor: Tools | Language names and make any any dummy changes or just click OK to apply the language names. Save the SIB file after this. Does this workaround the problem?
