Hello rayigo,

If you want the hide the screen shown in the Screenshots, you need to create a trigger with the following code:
Code: Select all
PMFDerivateCase(@@APPLICATION, @%INDEX);
G::header("Location: casesListExtJsRedirector");
die();
The task, where you want to hide this trigger, set this trigger to fire Before Assignment.

Hope this helps.

Best Regards,
Zainab Sabunwala

You can permanently remove the "Previous Step" link, by editing the file workflow/engine/templates/cases/cases_ScreenDerivation.html and changing the code from:
Code: Select all
                  {if $PREVIOUS_PAGE}
                  <td valign='top' class='tableOption' width='33%' align="left">
                  <table cellspacing="0" cellpadding="0" width='100%'>
                    <tr>
                      <td class='tableOption' align="left" width="120"><img src="/images/bulletButtonLeft.gif" width="6" />&nbsp; <a class="tableOption" href='{$PREVIOUS_PAGE}' id="form[DYN_BACKWARD]" name="form[DYN_BACKWARD]" onclick="">{$PREVIOUS_PAGE_LABEL}</a></td>
                      <td class='tableOption'>&nbsp;</td>
                    </tr>
                  </table>
                  </td>
                  {/if}
To:
Code: Select all
                  <!--
                  {if $PREVIOUS_PAGE}
                  <td valign='top' class='tableOption' width='33%' align="left">
                  <table cellspacing="0" cellpadding="0" width='100%'>
                    <tr>
                      <td class='tableOption' align="left" width="120"><img src="/images/bulletButtonLeft.gif" width="6" />&nbsp; <a class="tableOption" href='{$PREVIOUS_PAGE}' id="form[DYN_BACKWARD]" name="form[DYN_BACKWARD]" onclick="">{$PREVIOUS_PAGE_LABEL}</a></td>
                      <td class='tableOption'>&nbsp;</td>
                    </tr>
                  </table>
                  </td>
                  {/if}
                  -->
The problem is that this eliminates the Previous Step link for ALL processes. If you only want to eliminate the link for certain processes, then you need to add code like this to workflow/engine/methods/cases/cases_Step.php. In line 777, change this code:
Code: Select all
        case 'ASSIGN_TASK':
            $oDerivation = new Derivation();
            $oProcess = new Process();
            $aData = $oCase->loadCase( $_SESSION['APPLICATION'] );

            $aFields['PROCESS'] = $oProcess->load( $_SESSION['PROCESS'] );
            $aFields['PREVIOUS_PAGE'] = $aPreviousStep['PAGE'];
Add a array of IDs for processes which should not have the "Previous Step" link displayed:
Code: Select all
        case 'ASSIGN_TASK':
            //set to the IDs of processes which should not display the Previous Step link:
            $aProcessesNoPreviousLink = array(
               '12067430558ded97f8666c8026604805', 
               '20419177758dec3f7bedd17038026045', 
               '34414124958d30cc2853ae9014839646'
            );
            $oDerivation = new Derivation();
            $oProcess = new Process();
            $aData = $oCase->loadCase( $_SESSION['APPLICATION'] );

            $aFields['PROCESS'] = $oProcess->load( $_SESSION['PROCESS'] );
            if (in_array($_SESSION['PROCESS'], $aProcessesNoPreviousLink))
               $aFields['PREVIOUS_PAGE'] = null;
            else
               $aFields['PREVIOUS_PAGE'] = $aPreviousStep['PAGE'];
