Two options:

Normally, MIDAS data events are saved to ODB (via RO_ODB into /eq/xxx/variables) to make them go into the midas history (/eq/xxx/common/history > 0).

The function mhttpd_init() scans the custom page and installs handlers etc. for each modbxxx
element. If you create an modbvalue dynamically in your code, this is probably done after you
called mhttpd_init(), so the function has no chance to modify the dynamically created element.

There is a bug in the string handling when changing ODB string entries via the

I wanted to try to summarize the current situation with regards to the handling of strings through the MIDAS web interface.
During the last year, we started the switch-over to using the new mjson-rpc functions in the MIDAS webpages. As part of this work, changes were made that |

Further to my last message, I see that a midas version from 2013 does indeed display
links to arrays as I would expect (see attachment). Therefore the problem in later
versions is a bug rather than a feature.

23 Mar 2018, Stefan Ritt, Bug Report, link to an array element displays whole array in mhttpd

It might have worked some ~5 years ago, but it never really showed the target value of a link, just the
link itself. I reworked the code now to show both the link and the target of the link, so you can change
both in the mhttpd ODB page. Should be consistent now with odbedit. Have a look if it works for you.

the ODB currently is.

I'd like to use the mjsonrpc db_get_values method, but (as indicated in the
documentation) it returns all ODB keys as lowercase.

17 Feb 2018, Amy Roberts, Suggestion, respect capitalization option in db_get_values mjsonrpc method?

It appears I needed to read the documentation more closely - the method db_save
does respect key-name capitalization and solves my problem.
