Troubleshooting: Process Modeler flow shape images not rendering


On a Flow form, you select the Diagram tab to edit a flow in PRPC’s Process Modeler flow editor; however, the shapes and connectors for your flow diagram are not displayed on the screen. Not all developers in your organization are experiencing this issue.

This issue can occur if the ActiveX controls and plug-ins setting for Binary and script behaviors is set to Disable within your Microsoft Internet Explorer 9 browser Security settings for the Local Intranet zone. PRPC’s Process Modeler flow editor requires that the Binary and script behaviors setting be set to Enable.

It is possible that just this setting was changed, or it could be the result of someone changing the Security settings for the Local Intranet zone from the default of Medium-low to High.

Suggested Approach

In some cases, browser security settings may be tightened temporarily to mitigate the risks associated with a new and publicly disclosed vulnerability in Internet Explorer (IE). Prior to following the steps below to change your browser security settings, check with your Information Technology (IT) department to ensure that you have the most up-to-date IE security updates installed.

How to enable Binary and Script Behaviors in IE 9

  1. Open Internet Explorer.
  2. Click the Tools menu, then click Internet Options.
  3. On the Security tab, click the Local intranet icon, then the Custom level button.
  4. Scroll down the Security Settings list until you see ActiveX controls and plug-ins.
  5. For Binary and script behaviors, click Enable.
  6. Click OK, then click OK again.

PRPC’s Process Modeler flow editor will now correctly render the shapes and connectors for your flow diagram.
