Hi,
I need to link two collections, the second one filtered based on a parameter passed from the first one.
How can I retrieve this parameter?
I understand that this cannot be done within the Builder and I am writing specific code for this.
In other words, in collection A I have a list of items, I have added a link to the second collection where a parameter is passed.
In the model of the second collection I need to filter the query based on this parameter, but I cannot get the parameter.
Any solution for this or alternative?
Thanks in advance

You can use:
        $app = JFactory::getApplication();	
        $filtervar = $app->getUserStateFromRequest( "filtervar", 'filtervar',$this->state->get("filter.filtervar"));

This is what you call a component builder. I was able to master using this in a very short time and the resulting component works like a charm. Not just a basic component builder but a fully working component builder with forms fields tables all ready to go. You can make the list and item views to display in the front and back end. Also there is a great forum just starting to evolve and I'm sure this will grow very rapidly when you all realise how good this tool is.
