You are not allowed to interpret values in the parser if you want to support property replacement, so that’s going to be problematic.</pre>

Thanks for reminding me of this (again).<br>
<br>
One of these days I'm going to successfully internalize property
replacement vis-a-vis the parsers and the related usage of
FactoryBeans and BeanDefinitionBuilders inside of them. But
apparently not yet... <br>

<pre wrap="">
Slightly more typing but IMO simpler code is to build a FactoryBean. Give it a boolean setter "allowDelegation" and a Predicate setter "allowDelegationPredicate". The buildObject logic could have the "mustn't set both" logic. Then the parser 'just' has to strip the contents of the attributes and stuff them in to the Builder, Spring does the rest.</pre>

Thanks for the hints. That's what I did and it works perfectly.<br>

It strikes me that this might be difficult for a deployer to understand?</pre>

Probably, you're right.<br>

I wasn't thinking about property replacement etc. Without *that*
requirement my thought was it's pretty simple - look at the
attribute value and if it's true/false/1/0, treat it like a boolean,
otherwise treat it like a bean ref. But totally not worth it.<br>
