JParameter with params.xml definition file

[FRamonTB]

Hello all,

   I'm developing an MVC component and trying to use parameters in front-end. In one view of the component I coded:

   jimport( 'joomla.html.parameter' );

   $paramsdefs = JPATH_COMPONENT.DS.'models'.DS.'itemparams.xml';

   $params = new JParameter($item->params, $paramsdefs);

and it works well doing gets over the $params object. I do 

   $params->get('value','','group');

and it returns the right value. 

The problem is that the method:

   $params->getGroups()

Always return 'false'... I don't know why... 

My itemparams.xml file:

<root>

<params group="group">

<param type="text" name="value" size="10" label="a label:" description="a description" />

</params>

</root>

Any help will be apreciated. Regards: framontb

Is this in 1.5? Because you shouldn't be using DS and you shouldn't be using JParameter if you are in 2.5.

Yes, It's in Joomla 2.5 and I'm using DS and JParameter... shouldn't I?

I was trying to follow this doc: http://docs.joomla.org/Component_parameters

What I should use?

Thanks for you help !!!

Another Wiki article that needs updating: JParameter is deprecated; you should use JForm instead. DS should not be used anymore, for it has become superfluous as PHP handles slashes correctly nowadays, also on Windows.

On the other hand: deprecated means it is still available... So the question in the posting is still valid.What would the answer be?

Still available in 2.5 but won't be in 3 so really I would not use. I'm sorry I can't even remember how to use it.

True and not the best practice to use deprecated stuff when making something new, but in 2.5 it is still available and 2.5 is a Long Term Support version. So although the best support might be the advice to not use it, I´ll still give it a try:

The "default" attribute is missing in your parm. That might be the cause for  the internal $_xml variable not being an array now.
Try adding default="some default text" to your parm.

Thanks for your help. I will try with these doc: 

http://docs.joomla.org/Creating_a_custom_form_field_type

and these:

http://www.joomla25upgrade.com/joomla-25-tutorials/35-understanding-joomla-2-5-jforms.html

If you know another, please, let me know.
