Hi @cliffordsean,

Yes, build with COOK 2.0 (using the J2.5) mode for the time being.

Check the file in which you're calling the ...getInstance() method... Does it tell you which controller? Check there too.

Hmmmm, I have to admit that I'm unsure about J3.0!

Have you seen this: docs.joomla.org/Developing_a_Model-View-...ent/3.0/Introduction

Have you tried renaming the call to the legacy version?

hi

yes i have seen that and made those changes which solves those issues.

however i thought that components were running in J3 ? except for a few styling issues ?

as from what ive seen the components cannot run propperly in J3 for now (unless im doing something wrong?)

tnx

That was my understanding too!

Maybe J3 has been updated or something. As I said though, I'm not familiar with J3 and have no experience developing components for it.

I don't think that comparability will be too long.

Does your helpers folder contain a file called mvc.php?

If not, check you cook config and try setting JDom to complete.

I think that some of the Joomla version compatability evaluation takes place there. If you didn't have the MVC helper, try removing your 'legacy' updates and see if it works.

If it doesn't, apologies!

I've posted thread to admin to take a look also.

Hope it helps,

G

Hi everybody.

Admin is here and reading all your posts, but also working amazingly for you.

About Joomla 3.0, there is an important stuff to know, the Natives MVC base classes are now interfaces, and the classes we are commonly using have changed names. JModelLegacy (for instance)


Do not try to migrate for 3.0 because it is comming. In the corner, but still again 15 days I think.

At this moment, you will need to migrate your source to the new structure, and it will be the absolute last migration to do.

Be prepared for this migration because it is huge, but don't worry I am implementing a way that you will be able to keep your changes and regenerate your component afterwards. An amazing stuff working with an excellent overriding system.

Not everything will be possible with that, but it is a good start. Every PHP Class will be overladable and placed in a 'fork' directory.


Stay in touch, and do not try to migrate to 3.0 because even if it is close to Joomla 2.5, There are a lot of stuffs to do.

Your component will be cross compatible for 1.6 to 3.0 because the new structure allows you to do not think to the compatibilities. The component will manage by itself the cross compatibility layer.

So... hold on, we are almost there.

Next upgrade is very huge.
Coding is now a piece of cake
