Re: Strange null pointer error

Hi Michael, It’s an interesting problem with at first blush seems impossible but on second pass, looks plausible. That is clearly Wonder code so you can trace it and debug it. The line number 125 of ERXDatabaseContext.java is likely very accurate. Stepping through (mentally) I concur that

Re: Creating a EOModel in code

The APIs and syntax vary a bit in names but philosophically and design-wise it's very much the same. EOModeler will not work, there's a different tool called "Cayenne modeler", a standalone app. My primary DBs are MySQL and Postgres, both work fine with Cayenne. It's an established tool to say

Re: Creating a EOModel in code

so, my simple EOF/ERXKey qualifiers and stuff would work, I’d use EOModeler? MySQL works fine it sounds, I’m using AWS stuff myself… > On Jun 26, 2020, at 3:27 PM, Hugi Thordarson wrote: > >> Ok, so are all the cool guys using Cayenne now then? > > I've seen some pretty cool guys use it

Re: Strange null pointer error

Heh, ya, I figured you’d say that…and who does? I’m sure someone… If you don’t have a clue, read your SQL and find those timestamps and see what transactions were going on. If you can’t reproduce it, I’d guess you’ll want to turn up a bit of logging and just do a "hunt and peck” until you see

Ok, so are all the cool guys using Cayenne now then? I'm sure I should read some page about it rather than waste everyone’s time reiterating why it’s better and why we should be moving to that sort of thing etc. > On Jun 26, 2020, at 3:10 PM, Hugi Thordarson via Webobjects-dev > wrote: >

Re: Creating a EOModel in code

You might also want to take a look at Cayenne. It's well documented and we're eager to help where the docs fall short. And most importantly; it's an active and maintained project that didn't die over a decade ago :) - hugi > On 26 Jun 2020, at 19:04, Aaron Rosenzweig via Webobjects-dev >

Re: Creating a EOModel in code

Hi Don, Have a look at EOEntity and friends: EOAttribute, EORelationship. You can build them out and setup the “external” name for the column, etc. I did it once as an exercise many moons ago. The only practical use I got out of it was sometimes sanity checking keyPaths to see if they hit

Strange null pointer error

Hello everybody! We started to see a strange error: java.lang.NullPointerException at er.extensions.eof.ERXDatabaseContext._verifyNoChangesToReadonlyEntity(ERXDatabaseContext.java:125) at
