So, I’m trying to save an in-memory table to JSON and read it back later into the in-memory table. Using jfiles2 ver 2.28. The save is fine, but I have yet to see a load work. I either get a blank record in the memory table or an unexpected comma error. So, I’m following along in the debugger to s…

[image] dmjung: Observed behavior was blank records were added to some of the IMM tables. Did you see this post, posted recently? IP Driver and with IN-Memory Driver Caching - ClarionHub Be warned that the in-memory driver, despite what the documentation says, is not THREAD safe. Can you…

[image] dmjung: Here’s the saving code: JSON_DiskSave.SetTagCase(jf:CaseUpper) JSON_DiskSave.SetRemovePrefix(true) JSON_DiskSave.Start() Hi David I think setting those TagCase and RemovePrefix properties would achieve nothing as whatever you set them to would be overridden in .start() tha…

Hi Doug, you’re not showing your clarion structures, or an example of the JSON so it’s impossible to comment further than saying that your use of Start (as Geoff pointed out) is misunderstood. I recommend pasting your json code into capesoft.com \jfilescode and seeing what it generates for you. Ch…

Bruce, Well, you’re seeing the code after my messing with things over a couple weeks trying isolate what was going wrong. My understanding of .Start was to fully reset the object and I originally only had a single .Start before all the saves/loads, but in testing added it before each attempt. I di…

The documentation explicitly says that .Start does not reset SetTagCase, SetRemovePrefix, and a few other properties. I assumed I didn’t need the case thing since it was already generating json in uppercase. RemovePrefix didn’t seem to do anything since I ended up with the prefix in the json eithe…

I’m not using the IMM as a cache for an existing physical table but more as a smart memory queue that the templates treat like a table for browses. And I’m not multi-threaded/mdi. –David

I’m in Clarion 9.1 if that matters.

Removed all the extraneous messages and starts attempting to see what was happening and still working fine. Moved the code out of the procedures and back into routines. Added back the object. Still works OK, so I guess this is resolved, although I sort of wanted to know how I was breaking it. Cla…

[image] dmjung: Clarion sometimes makes me wonder about my career choices over the years. Something I’ve noticed working on the templates recently which might account for what you have seen, is changes made to a template dont always update so I have to remove the template and reselect the tem…

That might be true in c6, its not true in c11. In c11 template changes always apply (assuming you have the switch on.)

Does this kind of string slicing comparison work? jfiles / json
