> While working on the issue OFBIZ-7252, I found one problem in Form Widgets. When we use <alt-target> attribute in child form, the system should consider overridden <alt-target> in child form. This is default expected behaviour. But in this case, it is always considering the <alt-target> of the parent form.
> For example:
> {code}
> <form name="ParentForm" .....>
> <alt-target use-when="xyz != abc" target="executeParentTarget"/>
> ........
> </form>
> {code}
> {code}
> <form name="ChildForm" extends="ParentForm" extend-resource="........>
> <alt-target use-when="xyz != abc" target="executeChildTarget"/>
> ........
> </form>
> {code}
> In above example, expectation is 'executeChildTarget' target should get executed but actually 'executeParentTarget' is getting executed.
> When we looked into framework level code of Form Widgets, we got the following code snippets:
> ModelForm.java (Line: 380-388)
> {code}
> ArrayList<AltTarget> altTargets = new ArrayList<AltTarget>();
> if (parentModel != null) {
> altTargets.addAll(parentModel.altTargets);
> }
> for (Element altTargetElement : UtilXml.childElementList(formElement, "alt-target")) {
> altTargets.add(new AltTarget(altTargetElement));
> }
> altTargets.trimToSize();
> this.altTargets = Collections.unmodifiableList(altTargets);
> {code}
> Here we can see that all alt-targets present in parent form are added to the list first and then all alt-targets present in child form are added.
> This causes a problem as method getTarget() of ModelForm.java (Line: 1352-1384) returns the first element in the list as alt-target.
