I managed to have the installation of the trial version done on a clean DNN 4.5.5. After adding the module onto the page, it appears to have some javascript error at the left bottom of the page.

"Can't move focus to the control because it is invisible, not enabled, or of a type that does not accept the focus"

Any idea?

I do not think so. the related Host settings are shown below:

Page State Persistence: Select the mode to use to persist a page's state. This can either be a hidden field on the Page (Default) or in Memory (Cache).	Page Memory

Use Whitespace Filter: Select this to remove excess white space from the response sent to the client - this will result in a smaller download (10-15%) but it will make the html less readable.

I tried in FireFox, it looks OKay. The javascript error only appears in IE 6.0. Thanks.

Peter, I believe Chhavi has contacted you on this as well (we're about to roll back from DMX4 to DMX3 because the javascript error renders DMX powerless, but it has to do (at least in our case), with child portals.  It wasn't like this before we were on  DMX4.0.1, but when we went to DMX 4.0.6 patch that we ran into all this. Its causing DMX not to properly load on our child portals, which makes the product useless on those portals. fyi..we're running DNN4.5.5 as well.

Sorry, my previous post might be unclear, let me try again. We didn't seem to have any problem with DMX4.0.1 (although I don't think we tried it on child portals). We upgraded our live environment (which unfortunately is an intranet so we can't get you access), and applied 4.0.6. Now, DMX does not work properly in our child portals, so we are looking at rolling back to DMX3.

WhenDMX tries to load in our child portals, we get the above javascript message, the stylesheet isn't applied, and therefore the UI is a mess (ex. the dropdown menus are behind the folder names, etc...) and unacceptable for usage.

The error may not be the root cause, I'm not sure.

Hi Peter,

This error is still present even with 4.01 RC4. Whitespace filter OFF. I had GZip Compression, but turned that off to test. Same result. However, I am not seeing any obvious side effects as the above users have seen.

I am also getting a Javascript error everytime I add the DMX module to the page.

In IE 7 the error is being reported as, "Sys.UI.DomEvent is null or not an object".

In IE 6 the error is being reported as "Sys.Application is null or not an object".

Haven't updated to the latest patch but I hope today.

Thanks,

Stuart

Hi Peter,

Some further info on this. Aside from the persistent error listed above, I have also found that clicking around on various folders can cause another, more intrusive error.

The right side grid area goes into an endless loop attempting to refresh (the rotating arrows just keeps rotating). When this happens, another page error occurs which says:

Also, it seems this occurs most often (maybe exclusively) to non-admin users. The only way to clear it is to refresh the page (or leave page and come back).

If I can gather any addtional information to help you, please let me know.
