view_parameters question for tab navigation

Wednesday 22 March 2006 2:10:48 am

I've made a tab navigation with view_parameters variable pass in the url, this is my code:

{switch match=$view_parameters.tab}
	{case match=1}
		{def $tab1='class="active"'}
		{def $tab2=''}
		{def $tab3=''}
	{/case}
	{case match=2}
		{def $tab1=''}
		{def $tab2='class="active"'}
		{def $tab3=''}
	{/case}
	{case match=3}
		{def $tab1=''}
		{def $tab2=''}
		{def $tab3='class="active"'}
	{/case}
	{case}
		{def $tab1='class="active"'}
		{def $tab2=''}
		{def $tab3=''}
	{/case}
{/switch}

When click on a tab I pass to $view_parameters.tab the number of the tab I want to view , but in the first time $view_parameters.tab is empty and the debug show me this error:

Error: eZTemplate @ design/tlf_ita/override/templates/full/product.tpl:3[0] Mar 22 2006 11:13:07
