Into Products and Services multi-currencies is not loaded and dropped on save

• set more than one currency in vtiger
• edit a product (or service)
• modify currencies values ('more currencies>>')
• flag more than one Currency and set relative Price
• set one of these as Base Currency
• click Save and Save Product
• Edit again same product (or service)
• open 'more currencies>>'
• only Base Currency is loaded

this behavior is trasparent if I modify product, I don't open 'more currencies>>' and I save: rows into vtiger_productcurrencyrel are dropped

my fix

• file: include/utils/InventoryUtils.php

• function: getPriceDetailsForProduct(...)

• line: 936

• commented if($is_basecurrency){

    ...
    if ($cur_value == null || $cur_value == '') {
    	$price_details[$i]['check_value'] = false;
    	if	($unit_price != null) {
    		$cur_value = CurrencyField::convertFromMasterCurrency($unit_price, $actual_conversion_rate);
    	} else {
    		$cur_value = '0';
    	}
    } else { //if($is_basecurrency){
    	$price_details[$i]['check_value'] = true;
    }
    $price_details[$i]['curvalue'] = CurrencyField::convertToUserFormat($cur_value, null, true);
    $price_details[$i]['conversionrate'] = $actual_conversion_rate;
    $price_details[$i]['is_basecurrency'] = $is_basecurrency;
    ...

getPriceDetailsForProduct(...) function called in 'more currencies>>' and Price Books

I tested into Price Books (popup) too, and it's working fine

My testing was with 'Merge Request 93' merged on my vtiger installation (http://code.vtiger.com/vtiger/vtigercrm/merge_requests/93/diffs)
