Steps to Reproduce

run the example native-zk-if.zul

Current Result

the red label component in the 4th div doesn't render even though the condition around it is true <zk if="true"> in the lines above this problem doesn't occur

Expected Result

all labels (zk components inside native elements render correctly)

Debug Info

it seems only the last zk component inside native elements is affected (adding an additional unconditional zk component at the end fixes the problem - commented out in the example)

Root Cause

native elements compress into a single zk.Native widget with prolog/epilog, the last conditional <zk> element is missed somehow in this process

Workaround

1. don't use <zk if=> within native element and add the condition directly to the native element

instead of

	<zk if="${true}">
		<n:div>Visible
			<label value="ZK label" style="color:red"/>
		</n:div>
	</zk>

use

	<n:div if="true">Visible
		<label value="ZK label" style="color:red"/>
	</n:div>

2. (Alternative) add a <nodom> as the last child of the parent native element (commented out in attachment native-zk-if.zul)
