Thank you so much, chillworld, for your answer.

I checked for event firing from client the same way as you checked. In Chrome, "Inspect" then "network".

I found lang-addon.xml in zkbind-8.0.2.2.jar as you mentioned. I removed the Java annotation from JpaTextbox and added the XML annotation in my ownlang-addon.xml like you post above. It works also.

<?xml version="1.0" encoding="UTF-8"?>
<language-addon>
    <addon-name>myzkcomp</addon-name>
      <version>
      <version-class>net.bitreplay.Version</version-class>
      <version-uid>1.0-SNAPSHOT</version-uid>
      <zk-version>8.0.2.2</zk-version><!--

or later --> </version>

  <language-name>xul/html</language-name>

  <component>
      <component-name>jpatextbox</component-name>
      <component-class>net.bitreplay.JpaTextbox</component-class>
      <extends>textbox</extends>
      <annotation>
          <annotation-name>ZKBIND</annotation-name>
          <property-name>value</property-name>
          <attribute>
              <attribute-name>ACCESS</attribute-name>
              <attribute-value>both</attribute-value>
          </attribute>
          <attribute>
              <attribute-name>SAVE_EVENT</attribute-name>
              <attribute-value>onChange</attribute-value>
          </attribute>
          <attribute>
              <attribute-name>LOAD_REPLACEMENT</attribute-name>
              <attribute-value>rawValue</attribute-value>
          </attribute>
          <attribute>
              <attribute-name>LOAD_TYPE</attribute-name>
              <attribute-value>java.lang.String</attribute-value>
          </attribute>
      </annotation>
      <annotation>
          <annotation-name>ZKBIND</annotation-name>
          <property-name>errorMessage</property-name>
          <attribute>
              <attribute-name>ACCESS</attribute-name>
              <attribute-value>load</attribute-value>
          </attribute>
          <attribute>
              <attribute-name>CONVERTER</attribute-name>
              <attribute-value>org.zkoss.bind.converter.sys.ErrorMessageConverter</attribute-value>
          </attribute>
      </annotation>
  </component>
</language-addon>

Anyway, without this annotation it does not work for me while it work for you. So I inspect the LanguageDefinition using breakpoint debugger and what I get from (It's kotlin syntax)

LanguageDefinition._ldefByName.get("xul/html")._compdefs.get("textbox")._annots

is

[annot:{value={ZKBIND=[@ZKBIND(ACCESS=[both], SAVE_EVENT=[onChange], LOAD_REPLACEMENT=[rawValue], LOAD_TYPE=[java.lang.String])], default-bind=[@default-bind(access=[both], save-when=[self.onChange])]}, errorMessage={ZKBIND=[@ZKBIND(ACCESS=[load], CONVERTER=[org.zkoss.bind.converter.sys.ErrorMessageConverter])]}}]

And from

LanguageDefinition._ldefByName.get("xul/html")._compdefs.get("jpatextbox")._annots

I get null.

Is this the expected thing?
