Re: [jibx-users] post-set method not working..what am I doing wrong?
The problem is that I'm using the default attribute to set each element value to the empty string if it doesn't exist, so nothing is ever null. Right now I've had to settle for doing similar to what you suggested as your second option, but I don't really like it because, since nothing is ever null, I use the empty string for comparison. So if all the subelements in my optional structure are empty, then the boolean never gets set. I'm just curious as to why post-set doesn't work in this instance. Is there a reason for this?

It's probably best if you can show an example of what you're trying to do, with the fragment of the binding definition and the actual post-set method code. - Dennis Beet wrote: The problem is that I'm using the default attribute to set each element value to the empty string if it doesn't exist, so nothing is ever null.

Re: [jibx-users] post-set method not working..what am I doing wrong?
Here's the fragment from the mapping file: ... structure name=Batch usage=optional test-method=hasBatch post-set=postset value name=TS style=attribute field=ts/ value name=MaxKG field=maxKGPerBatch/ /structure ... it doesn't matter what I put into postset because it doesn't ever get called. I've run a debugger and it never stops in that method.

Re: [jibx-users] post-set method not working..what am I doing wrong?
Okay, that makes it clear. The post-set method (along with factory, pre-set, and pre-get) only get used when there's an object associated with the structure. In this case you don't have an actual object, just some contained fields. If you go up a level (or more) to where you have the definition of your actual object (generally either as a mapping element or a contained structure that references a field of the containing object) you can use the post-set method there. It should really be an error to specify post-set on a structure that doesn't define an object. I'll add a check for this in the beta 4 code, which has much better error checking and handling in general. - Dennis Beet wrote: Here's the fragment from the mapping file: ... structure name=Batch usage=optional test-method=hasBatch post-set=postset value name=TS style=attribute field=ts/ value name=MaxKG field=maxKGPerBatch/ /structure ... it doesn't matter what I put into postset because it doesn't ever get called.

Re: [jibx-users] post-set method not working..what am I doing wrong?
okay, I see what you're saying... the problem with going up a level is that you lose the level of granularity you sometimes need. I know that you listed some workarounds before, and that's what I'm using right now, but it seems like it'd be a nice little 'enhancement' to allow method hooks at this level. Or is it just not possible? I admit I haven't seen the source code, so maybe I'm just not getting something.
