In OnBase 15, E-Forms that contain jQuery 1.5 or earlier will no longer render as expected. You may also run into rendering issues with other OnBase clients rendering older HTML, such as E-Forms that have not been updated to conform to Windows IE 9 standards. If your E-Forms were created based on the Windows IE 7 standard, those forms will not render as expected.
OnBase 15 requires all E-Forms to be written to the IE 9 standard or later. Forms with jQuery must utilize version 1.6 or higher. These restrictions were present in the OnBase 14 Web Client. In OnBase 15, the Unity Client and OnBase Client have the same restrictions. If a solution's E-Forms have been developed with OnBase Unity Forms, the forms will render as expected. It is worth noting that when developing forms going forward, forms created as Unity Forms are assured to work with future versions of OnBase.
Keep this in mind when running the upgraded version of obunity.exe or obclnt32.exe. Running a version OnBase 15 executable on a workstation may cause rendering issues with previous versions of OnBase on that workstation. For this reason, extra testing and planning should take place before any new Client executables are launched on users' workstations.
