Issue with calling a method activity before page render

Question

Hi All,
I am using Jdeveloper 11.1.1.7.
I am trying to achieve the approach defined in "1.b. Calling a Method in Backing Bean:" elaborated in the blog - https://blogs.oracle.com/adf/entry/an_epic_question_how_to
As illustrated, I defined a default method activity (binding to a method in managed bean) and a view activity activity in a bounded task flow.
When I launch the application (running the view activity), following error is encountered -
oracle.adf.controller.metadata.ParsingException: ADFC-02020: Cannot find default activity 'check' in task flow definition '/WEB-INF/task-flow-definition.xml#task-flow-definition'.
    at oracle.adfinternal.controller.metadata.model.xml.XmlUtil.createAndLogParsingException(XmlUtil.java:474)
    at oracle.adfinternal.controller.metadata.model.xml.MetadataResourceXmlImpl.parseTaskFlowDefinition(MetadataResourceXmlImpl.java:507)
    at oracle.adfinternal.controller.metadata.model.xml.MetadataResourceXmlImpl.parse(MetadataResourceXmlImpl.java:361)

    at oracle.adfinternal.controller.metadata.provider.mds.MdsMetadataResourceProvider.getMDSCachedResourceOrParse(MdsMetadataResourceProvider.java:732)
Please advise.

Hi Cvele, Timo,
Many thanks for the suggestions.
To avoid confusions, I have created a new application altogether. It seems that the method call is not being called when I run the page.
For your reference I have attached the task flow definition and method code below -
Task Flow Definition
<?xml version="1.0" encoding="windows-1252" ?>
<adfc-config xmlns="http://xmlns.oracle.com/adf/controller" version="1.2">
  <task-flow-definition id="task-flow-definition">
    <default-activity id="__1">methodCall1</default-activity>
    <managed-bean id="__11">
      <managed-bean-name id="__13">TestBean</managed-bean-name>
      <managed-bean-class id="__10">TestBean</managed-bean-class>
      <managed-bean-scope id="__12">request</managed-bean-scope>
    </managed-bean>
    <view id="view1">
      <page>/view1.jspx</page>
    </view>
    <view id="exception">
      <page>/exception.jspx</page>
    </view>
    <method-call id="methodCall1">
      <method>#{requestScope.TestBean.checkURL}</method>
      <return-value id="__15">#{TestBean.checkURL}</return-value>
      <outcome id="__14">
        <to-string/>
      </outcome>
    </method-call>
    <control-flow-rule id="__2">
      <from-activity-id id="__3">methodCall1</from-activity-id>
      <control-flow-case id="__5">
        <from-outcome id="__6">go</from-outcome>
        <to-activity-id id="__4">view1</to-activity-id>
      </control-flow-case>
      <control-flow-case id="__8">
        <from-outcome id="__9">error</from-outcome>
        <to-activity-id id="__7">exception</to-activity-id>
      </control-flow-case>
    </control-flow-rule>
  </task-flow-definition>
</adfc-config>
Method Code
public String checkURL() {
// Add event code here...
System.out.println("method activity called");
return "error";
