If-Then Condition [message #750134]

I am in situation where I am loading two models with separate DTD's. There are few properties in the model that is available for one version and not available for other. So when defining the SDEF i decided to go with the If..then construct by evaluating a certain Transient property.

<if>
<condition>
	<class>HookVersionEvaluator</class>
	<parameter>v5_2_0</parameter>
</condition>
<then>
     <property-editor>CustomJspGlobal</property-editor>
</then>
</if>

My condition is getting evaluated correctly and am getting the expected boolean value.
On true am seeing the property editor on the page, but I am facing issue when its "false", my perception and understanding is that the Property "CustomJspGlobal" will not be shown when the HookVersionEvaluator#evaluate returns "false", but am getting an Quote:

java.lang.RuntimeException: Could not find property CustomJspGlobal in ....

, so when "false" the model is different and it cant find CustomJspGlobal so i was thinking that framework will skip this property rendering.

Any idea whats wrong here ?, and not sure why on false the property rendering or evaluation is happening ?

The if-then construct is currently implemented by initializing parts for both branches, but only rendering the appropriate branch. This isn't usually a problem, except in cases like yours. To make it work in your case and also for better performance, we should probably doing branch init/dispose on condition change. Please open a bug.
