Is uCompents still alive?

I just tried to go to the uComponents website and it shows the site is dead and the domain is for sale. Is this project still alive?

Hi Connie,

The documentation site is available here: http://ucomponents.github.io/

I let the domain name expire, it ended up costing me personally.

As for the project status... I guess inactive is the best term for it. The source-code is still available and there's no reason that bugs can't be fixed and patch releases made.

For me personally, since using Umbraco v7, (3.5 years ago), I haven't needed to revisit v6 or further uComponents.

Cheers,
- Lee

Thanks Lee. I still have two Umbraco 6.x sites to support and am getting errors recently. Looks like time to upgrade from uComponents 5.5.x. The upgrade fixes the known bug, just hope it won't break anything else. I don't recall all the places its used.

From what I recall, it should be straight forward to upgrade from uComponents v5.x to v6.latest.

At the time of release I outlined all the potential breaking changes...

v6.0 - http://ucomponents.codeplex.com/releases/view/97718

There were no breaking changes in v6.1.x https://github.com/uComponents/uComponents/releases

I hope this helps?

Cheers,

Something changed in uComponents.XsltExtensions.dll enough to cause my iframe XSLT to fail. It's pretty basic:

Hi Connie,

I'm not sure... there's no mention of uComponents extensions being used in that XSLT. Are you getting an error message?

All I get is this:

Error parsing XSLT file: \xslt\iFrame.xslt

Next I'll see if I can breakdown that xslt and see if I can identify what line is causing the error.

Ok, this might be more helpful... if I save the xslt with uComponents 5.x there are no errors or issues. After upgrading to uComponents 6.x, I try and save that same xslt with no changes it won't save and throws this error:

Error occured

Ooooo, another issue... just tried to create a new blank xslt and it throws this:

I think it might be this one... http://ucomponents.codeplex.com/workitem/14781

If you check your "config\xsltExtensions.config" file, if there are any uComponents entries, then remove them.

Fingers crossed that should work.

I took this out of the xsltExtensions.config...

and everything looks good so far. Do I need any of those or are these relics from past versions?

No need for them... they are relics from Umbraco v4! (aww nostalgia) :-)
