you can use setAttribute instead.

if your code need to migrate to future version of ZK, you will have compiling error after compiling.

Like "deprecate" means in ALL Java libraries, it means the API is kept there for "backward compatibility and might be removed in the future". So new created application will not "misuse" the API again.

The replaced method shall be written in Java doc of the "deprecated" one and take a detail look on the "Upgrade Note" of the ZK release-note.

The attribute seems no datasource for EL. I use this sometimes to get the same name for EL's and @databinding ("controller", "model").

This smalltalk (Fusioncomposer) uses setVariable for EL.
How is the new way for register a EL-Datainterface?
(like this smalltalk)

Note: I use actually cmp.setVariable("controller", this, true); to set the composer as datasource controller for EL.

You can do this by implements you own Variable Resolver interface: org.zkoss.xel.VariableResolver, and use it like this:
<?variable-resolver class="org.zkoss.zkplus.spring.DelegatingVariableResolver"?>

@Robert,

Use cmp.setAttribute("controller", this, Components.SPACE_SCOPE) instead. It is almost identical to cmp.setVariable("controller", this, true)

cmp.setVariable keeps value (the "this") in component "cmp"'s ID space owner. And EL can refer it via its given key "controller".

Henri, Iantsai

thanks for the answers. There are 2 threads. We found the answer in the other thread.

Other Thread

in short:
cmp.setAttribute("controller", this, Components.SPACE_SCOPE) works for EL, but not in the old ZK-Versions (i've changed my 3.6 example).
