Debug Info

Root Cause

ForEachRenderer is adding a variable resolver to the current execution in each iteration
https://github.com/zkoss/zkcml/blob/v8.6.1/zuti/src/org/zkoss/zuti/zul/ForEachRenderer.java#L64

But doesn't clean it up.

A template defined in a zul page uses TemplateImpl which does the clean up by default, but also adds the VariableResolver.

(adds the same variable resolver again)
https://github.com/zkoss/zk/blob/v8.6.1/zk/src/org/zkoss/zk/ui/impl/UiEngineImpl.java#L2307
(removes it)
https://github.com/zkoss/zk/blob/v8.6.1/zk/src/org/zkoss/zk/ui/impl/UiEngineImpl.java#L2341

Workaround

manually remove the variable resolver during template.create
