I looked into it, and I think this is because of some undocumented details of the mjUI implementation.
Specifically, the char array used for EDITTXT fields is assumed to have a length of mjMAXUITEXT, which is 300. Try replacing 200 with mjMAXUITEXT and see what happens.
That solves the issue and explains the seg fault. Thank you!
I need to add a text field to the task section of the UI for a feature I'm implementing. I add a field in task.h as such:
char myText[200] = "";
And then add this line to defTask[] in agent.cc:{mjITEM_EDITTXT, "My Text", 2, ActiveTask()->myText, ""},
MJPC runs just fine but as soon as I click on the text field and edit or just click elsewhere right away, I have a seg fault in
InternalResidual()->Update();
called fromThreadSafeTask::Transition
. It seems liketask_->parameters
is undefined during this update. I have trouble understanding why this happens since the text field should not have anything to do with the parameters definition. I would really appreciate some help with this.It's worth noting that I don't have this issue for any other type of mjtItem_, for example mjITEM_EDITINT works just fine.
Last time I merged with the repo was on Sep 14th, commit ab5edf26361323c8d4de4ee61ae40ddcca61b66c.
