When multiple models are loaded, postprocessing is performed only on the first one

[vlkong]

Let's consider this code:

 main
 {	
	function loadAndSolve(model_mod, model_dat) {
		writeln("Solving " + model_mod);	
		var cplex1 = new IloCplex();
		var source1 = new IloOplModelSource(model_mod);
		var def1 = new IloOplModelDefinition(source1);
		var opl1 = new IloOplModel(def1, cplex1);
		var data1 = new IloOplDataSource(model_dat);
		
		opl1.settings.mainEndEnabled=true;
		opl1.addDataSource(data1);
		opl1.generate();
		
		if (cplex1.solve())
		{
			writeln("successfully solved " + model_mod);
			opl1.postProcess();      
		}
		else {writeln("No solution found for " + model_mod);}  
			
		opl1.end();
	}
	loadAndSolve("model1.mod", "model1.dat");
	loadAndSolve("model2.mod", "model2.dat");
 }

We expect that model1.mod is loaded/solved, then any output for model1.mod to be saved.
Then model2.mod is loaded/solved, then any output for model2.mod` is saved.

However only the output of model1.mod is triggered.

The reason for this behaviour is that db connection update() statements are triggered at postprocessing, but the postprocessing callback is only registered to the first model. Working on a fix + tests for this.

fixed in 1.13.4

1.3.4 did not contain the right changes
Right changes are in 1.3.5
Sorry
