Some times the IE compatibility mode is enforced to be used by your system admin at an enterprise level, especially for the intranet sites. Since Jdeveloper 11.1.1.6, a popup warning is shown to the user when ADF/WebCenter application is running on compat mode. The issues seen in compat mode is not supported by Oracle. The solution to bypass the compat mode has been documented via Oracle Doc 1555476.1. I'd like to extract the key information of the such solution here: A new feature has been introduced in JDeveloper/ADF 11.1.1.7.0 and 11.1.2.4.0 and backported to 11.1.1.6.0, 11.1.2.0.0, 11.1.2.2.0 and 11.1.2.3.0 through patch 14400317. It consists of bypassing Compatibility Mode in IE browsers. The ADF framework will force the target document to the maximum document mode supported by the browser using the X-UA-Compatible META tag.
