Example 41 with ExpressionCompiler

use of org.mule.mvel2.compiler.ExpressionCompiler in project mvel by mikebrock.

the class CoreConfidenceTests method testStringConcatenation.

public void testStringConcatenation() {
    // debugging MVEL code, it seems that MVEL 'thinks' that the result of the expression:
    // "Drop +5%: "+$sb+" avg: $"+$av+" price: $"+$pr
    // is a double, and as so, he looks for a method:
    // Services.log( double );
    // but finds only:
    // Services.log( String );
    // raising the error.
    String ex = "services.log((String) \"Drop +5%: \"+$sb+\" avg: $\"+$av+\" price: $\"+$pr );";
