Hi orkhan, welcome to the forums
I assume MyLoopFunction() is a function in your Page_Controller? That will not work within the <% control AllChildren %> loop because it returns a set of Page objects (the data model class), not Page_Controllers. So in order for this to work, you'd have to define the MyLoopFunction() funtion in your Page class instead.

<?php
class Applications extends SiteTree {
....
}
class Applications_Controller extends ContentController {
.....
function MyLoopFunction($id=1) {
$children = DataObject::get("SolutionsPage", '`SolutionsPage_AppsTypes`.`AppsTypeID` = '.$id, "Created DESC", "LEFT JOIN `SolutionsPage_AppsTypes` ON `SolutionsPage_AppsTypes`.`SolutionsPageID` = `SolutionsPage`.`ID`", 100);return $children;
}
}This is my Applications class extends to SiteTree
What there is not true?

As martimz says - context is wrong. Control is not just a "loop" but also changes "context" you start out int he Page_Controller object, then you move context into the Page object. This is changing to be more clear in SS3.
Just try moving your function from "Applications_Controller" to "Applications" and see what happens...

you can only pass fixed strings into methods on the template - whereas $Pos may provide a number when merged it cannot be used as a function paramter.
This comes up over and over, so I have a post to refernce for you now...
