Subject Re: Problems with save() method with Peer class
Date Thu, 07 Aug 2003 14:34:54 GMT
probably just a configuration problem, but worth noting I've 
had that problem (or something very similar) ever since I 
started using torque. 

I've never been able to find out from anyone official what's 
causing it, but I suspect its a problem (for me) that 
sneaks in when my torque setup is serialized during a 
tomcat restart/ schema change. (I use postgresql)

If there isn't just something stupid wrong with your 
Torque.properties file I solved it by doing this just after 
I initialised Torque,

CustomerMapBuilder customerBuilder = 
	new CustomerMapBuilder();

ie rebuild the offending map.

i also did this in my copy of Torque.java initialize(c) 
function and recompiled,

if (mapBuilders == null) 
  mapBuilders = 
    Collections.synchronizedList(new ArrayList());

I'd love to know if there's a better solution / official 

I'm using 3.0.2 and torque standalone with struts,
