title: Failed to create creation time in APEX report
body: <p>I am using Oracle APEX to build a interactive report. In the create page I want to inert a field called create_time in the database which is not shown on the create page. Similarly, in the edit page, I want to update a field called update_time in the database.</p>
  
  <p>For the edit page, I added a process and set the plsql code to: </p>
  
  <pre><code>update table_test t set t.UPDATE_DATE = sysdate 
         where t.ROWID = :P2_ROWID;
  </code></pre>
  
  <p>And this works.</p>
  
  <p>However, when it comes to the create page, I set the plsql code to:</p>
  
  <pre><code>update table_test t set t.CREATE_DATE = sysdate 
         where t.PROJECT_ID= :P3_PROJECT_ID; 
  </code></pre>
  
  <p>This didn't work. Then I hardcoded the where clause to sth like this: where t.PROJECT_ID='100', and I create a project with id = 100, and it works! So I suppose, for some reason this :P3_PROJECT_ID failed to fetch the value. Anyone knows why? And is there any other ways to insert create_time other than using process? Thanks! </p>
