Populate method in Template: Not working as expected [message #1750658]

Hi,

Please find my code below.

var template:Template = TemplateFactory.load("body.egl");

for(class:Mine!Class in Class.allInstances) {
template.populate("cls", class);
template.generate(class.name + ".java");
}

Here I am calling the 'body.egl' file which has a variable called 'cls'. I was expecting the 'cls' variable to have different values inside the 'body.egl' file depending on the value of the 'class' variable in the for loop. Surprisingly, although it generates files with different names for different loop iterations, for different instances of 'body.egl' content, it only uses the value assigned to it during the first loop iteration. Am I wrong in terms of my expectation? Should I do it differently for making a variable available in the 'body.egl' file?

Thanks

Hi John,

Templates are not reusable so to make this work you should move var template:Template ... into the for loop. Alternatively, you may want to consider using EGX, which provides a more elegant syntax to orchestrate the execution of your templates [1].

Cheers,
Dimitris
