MINILANG COOKBOOK
=================

* How to get results of a Java static method in minilang

  Use set and bsh:
<set field="notApplied" value="${bsh:org.ofbiz.accounting.invoice.InvoiceWorker.getInvoiceNotApplied(invoice)}" type="Double"/>

WARNING: YOU MUST USE type="" TO CAST YOUR RESULT.  Otherwise, it will be a String.

* How to invoke Java from inside minilang

  You can actually insert blocks of beanshell code right into minilang, like this example 
from applications/ecommerce/script/org/ofbiz/ecommerce/customer/CustomerEvents.xml:
        <call-bsh><![CDATA[
            String password = (String) userLoginContext.get("currentPassword");
            String confirmPassword = (String) userLoginContext.get("currentPasswordVerify");
            String passwordHint = (String) userLoginContext.get("passwordHint");
            org.ofbiz.securityext.login.LoginServices.checkNewPassword(newUserLogin, null, password, confirmPassword, passwordHint, error_list, true, locale);
        ]]></call-bsh>

  Each variable from minilang is automatically accessible here in beanshell.

 

* Clear vs. Refresh

  <clear-field field-name="foo"/> sets it to null.  It can be either a field or a Map/GenericValue
  <refresh-value value-name="foo"/> gets the value of a GenericValue foo from database again.  foo MUST be a GenericValue for it to work.

* How to set a Boolean value

   I could not find any examples of this but fortunately got lucky doing this:
   <set field="orderAvailableCtx.countNewReturnItems" value="true" type="Boolean"/>

   I think what minilang does is call the constructor for type="" using the string of value="".  I guess one of these days I should look at the code to see if I'm right...
