When running ADF applications in Internet Explorer, problems will occur when the browser setting Enable native XMLHTTP support is turned off.

According to the following blog:

Script For Detecting Availability of XMLHttp in Internet Explorer

It states:

Having the XMLHttpRequest API available is key to any ADF Faces Rich Client application.
Without XMLHttpRequest available, your ADF Faces application will simply not work correctly.

Unfortunately, it is possible for users to switch off this option in Internet Explorer as a Security setting..
It allows users to turn off this setting without knowing the full implication or affects it will have on their application, which in turn when de-selected can cause major problems.

There does not seem to be any warning to users warning or stating the full implications of having the option Enable native XMLHTTP support disabled.

Simple Testcase

Here we will show a simple scenario on what can happen when Enable native XMLHTTP support is disabled.
  • At this stage Enable native XMLHTTP support is enabled.
  • Run a JSPX page that contains ADF components i.e. Panel Accordion, Panel Tabbed, menus etc.
  • When the application is running in Internet Explorer perform a function like select an accordion or a tab, where all functionality will work as expected.

  • Go to Tools | Options.
  • Select Advanced Tab.
  • Settings section: De-select option Enable native XMLHTTP support and press [OK].

  • Re-run/refresh the application and again perform some ADF function however this time problems will occur i.e. tabs are not displayed, correctly, menus will not invoke etc.
