Plugin does not works with nvim_jdtls

[rishabh3]

I use nvim_jdtls for java integration and tried to use this plugin. I have added the code require'lsp_signature'.on_attach() in jdtls on_attach function, but this plugin always gives the following error.
Error executing vim.schedule lua callback: ...cker/start/lsp_signature.nvim/lua/lsp_signature/init.lua:221: attempt to index local 'actSig' (a nil value) stack traceback: ...cker/start/lsp_signature.nvim/lua/lsp_signature/init.lua:221: in function 'handler' ...l/Cellar/neovim/0.6.0/share/nvim/runtime/lua/vim/lsp.lua:957: in function 'cb' vim.lua:285: in function <vim.lua:285>
I know this plugin does not support nvim_jdtls, but can this be added as enhancement or this is something not feasible?

I get a very similar error with omnisharp/mono but only sometimes.

Please check this issue: #97
I think jdtls dose not enable active parameter by default. You need to setup the jdtls to enable it.
As for omnisharp, would you send me the function signature so I can reproduce it? I think it might be incorrect format of omnisharp response. thanks!

Hi @ray-x ,
I did try to go through the issue you had tagged, in your previous comment. What I see is that although I have signature help enabled, I still see the same issue I have reported above when I add the require'lsp_signature'.on_attach() call in my jdtls config.
Here is a link to my java config: https://github.com/rishabh3/nvim/blob/new_structure/ftplugin/java.lua#L85
I do get lsp_signature from jdtls and the documentation as well, but it does not work with this plugin.

Updating the plugin works, seems i was running some old version or something was missing
