ABAP Webdynpro Development - Script Error when Accessing Visual Elements

Question

I am encountering a strange error at my client .  I can't use the Abap Webdynpro visual elements to build views .
To reproduce the error :
- T-code SE80
- Open up any ABAP webdynpro component .
- Open up one of the view  and go on Tab Layout .
Normal Screen : You would see many WYSIWYG items ( buttons, radiobutton , text elements etcu2026. ) at the left side u2026 these elements are used to build the view .
Here : No elements displayed and when we click on that area we get an error   . 
Instead of the elements to get displayed .. lines are displayed and when you try to open up ( click ) the lines , an internet explorer script error stating the following occurs ( although the abap wendynpro is edited in SAP Gui ) :
An Error has occured in the script on this page .
Line : 1
Char : 25
Error : Object Required

Anybody had had the same kind of error before ^^????
Thanks and Best Regards !

Recently, we have upgraded our ERP system (SAP ECC 6.0 SPS17) with EHP4 SPS8. SAP_BASIS and SAP_ABA patch level same on 701_0008.
FQDN is mantianed at icm/host_name_full parameter in system as well as in /etc/hosts file with associated system IP address.
As suggested by  Ted Dinh,  we do not find any duplicate MIME files in our MIME Repository (SE80) and we cleared/invalidated  ICM cache many times in problem analysis.
As suggested by  Thierno Diarra , in our affected system domain WDY_MD_UI_ELEMENT_CATEGORY is well maintained in value ranges.
We have raised SAP OSS Message for the same, they told us to check dns server connectivity/settings with the affected system. we did the suggested DNS settings in affected system. But  still the same error message is occuring. They have suggested same sap notes like #979039 and #1009930 & #1483210 , but all the corrections/suggections/SICF service status as mentioned, are found OK in our system.
