Visualforce component is not supported- Issue resolution on Force.com platform

Hi,

This blog post deals with common error thrown BY Force.com: is not supported.

You can raise a case from Salesforce.com partner portal for enabling Dynamic visualforce component in your organization under "Feature Activation" item for case. Salesforce.com team will ask for OrgID for doing so. So it would be quick if you could provide your OrgID while raising the request asking like "I want to enable dynamic visualforce component in my org with orgID:". They will enable within 1 working day( based on my experience).

If you have already enabled the dynamic visualforce components feature in your Salesforce.com organization and still getting this error, then the problem lies with version number of Visualforce page.

I came across such situation where even after enabling this feature I used to get such message. On analysis I found that the root cause was VF page version number:

You get such error in this case: If you are navigating from a VF page whose version number 18 to a VF page whose version number is 24. Since version 18 doesn't support dynamic visualforce components, so when Force.com runtime engine is navigating user from a page (v18 ) to page (v24) it somehow doesn' t take into account the version number of target page i.e. 24 and assumes version of target page as 18 and thus throws such error.

I hope this post will help you to resolve this issue.

Cheers !
