I have a problem with selecting a property on a compartmentshape of a dsl. What I want to do is:
I have a DSL with one compartmentshape which has many properties in one compartment. Each of this properties has a textfield which is used for saving c# code. I compile this code and add the error tasks to the error list. I added an event handler for the navigate event of the error task. Inside this handler, i would like to select the property of the compartmentshape which is responsible for the error. I tried many things, but didn't succeeded. This is my current selection logic:
public void Select(Rule rule)
{
Library.Field ruleField = rule.Field as Library.Field;
var ruleFieldPresentation = PresentationViewsSubject.GetPresentation(ruleField as ModelElement).FirstOrDefault() as ShapeElement;
VSDiagramView activeDiagramView = Diagram.ActiveDiagramView as VSDiagramView;
if (activeDiagramView != null)
{
var docView = activeDiagramView.DocView;
activeDiagramView.Selection.Clear();
docView.CurrentDiagram.ActiveDiagramView.Selection.Set(new DiagramItem(ruleFieldPresentation));
}
}
The problem seems that an property of the compartmentshape doesn't have a presentationview, because I'm not able to get it.
I would be glad and very grateful if someone can helpe me with this problem.
Thank you
Regards Manuel
I wanted to open an error from the error list. There is a better solution than using the navigation event on an error. The better solution is to add a validation rule to the domain class and add the error with the context to the error list. Than the navigation to the property works out of the box.
context.LogError(errorDescription, "GAIN001RuleCompilationError", Field);

I have created cascading dropdown. I need to load dropdown based on parent dropdown selection. I am trying to use onpropertychange event. but I am getting error on super.onpropertychange saying {Property 'onPropertyChange' does not exist on type 'BaseClientSideWebPart'.}
please let us know what I havve missed.
protected onPropertyChange(propertyPath: string, newValue: any):void{
if(propertyPath === "listDropDown"){
// Change only when drop down changes
super.onPropertyChange(propertyPath,newValue);
// Clears the existing data
this.properties.ItemsDropDown = undefined;
this.onPropertyChange('ItemsDropDown', this.properties.ItemsDropDown);
// Get/Load new items data
this.GetItems();
}
else {
// Render the property field
super.onPropertyChange(propertyPath, newValue);
}
}
Instead of onPropertyChange, perhaps you mean onPropertyFieldChanged from the BaseWebPart class?
The error message is accurate - web parts don't have a method called onPropertyChange. The above sounds like the closest match for what you are trying to do. Note that it takes not two arguments, but three: propertyPath, oldValue, and newValue.
using rxBindings im trying to slow down a click event but i would like to know what the parameter is need.
For example, here is a call i am doing on a imageview. So ImageView v;
RxView.clicks(v)
.throttleFirst(400, TimeUnit.MILLISECONDS, AndroidSchedulers.mainThread())
.subscribe(new Consumer<Object>() {
#Override
public void accept(#io.reactivex.annotations.NonNull Object v) throws Exception {
showBottomSheet(getAdapterPosition());
}
});
but im im not sure what the parameter in accept should be ?
I was expecting i would get the view here but when i try changing the type to View i get an error of no such method.
If you look at the source code of the Observable generate using RxView.clicks(), you will see that when the click happens, the following code is triggered:
observer.onNext(Notification.INSTANCE);
that is defined in the library, as:
public enum Notification {
INSTANCE
}
It is just a convenient way for indicating that the event happened, it doesn't carry any extra information.
I am facing the following problem,
I have an object called "data". It has three properties, one of it being itemRendererData. The "itemRendererData" is an ArrayCollection of objects having many properties one of which is the property "imageURL" (datatype:String).
I am working in flex. I have defined the view and the item renderer properly. The view has the data. I am supposed to get the images from the url specified by imageURL property.
In the itemRenderer, I have declared, source
source = {data.itemRendererData.imageURL}
But the images are not being displayed.
Use a the FlexEvent.DATA_CHANGE handler rather than binding, which is actually the proper way to handle this and gives you far more control.
public function CustomItemRenderer() {
this.addEventListener(FlexEvent.DATA_CHANGE, this.dataChangeHandler);
this.addEventListener(FlexEvent.CREATION_COMPLETE, this.creationCompleteHandler);
}
private function creationCompleteHandler(e:FlexEvent) {
if (this.data) {
this.image.source = this.data.itemRendererData.imageURL;
}
}
private function dataChangeHandler(e:FlexEvent) {
if (this.data && this.initialized) {
this.image.source = this.data.itemRendererData.imageURL;
}
}
You will notice that I have a handler for FlexEvent.CREATION_COMPLETE as well. This is because the data is actually set before the components are created. So the first time a renderer is loaded, this.image is null and this.image.source will error out.
If that doesn't work, you also need to make sure that the Image/BitmapImage is not a direct child of the renderer. I never did figure out why this was, but adding it as a child of Group fixed that issue where the image was being set but not rendering. Again, I have no idea why this was and I tested for a few hours trying to figure it out.
As an added tip, avoid MXML-based ItemRenderers in mobile applications. They are noticeably slower than pure-AS3 renderers.
I'm trying to generate some additional code base on the auto-generated webservice proxies in my VS2010 solution, I'm using a T4 template to do so.
The problem is, automatically generated proxies are added in "Service Reference" folder but ProjectItems (files) are hidden by default and the following code does not find them in the project structure:
var sr = GetProjectItem(project, "Service References");
if(sr != null)
{
foreach(ProjectItem item in sr.ProjectItems)
{
foreach(var file in item.ProjectItems)
{
//Services.Add(new ServiceInfo { Name = file.Name });
}
}
}
The above code runs and although service reference is found, and there are ProjectItems under that node (named by the webservice reference name), under object under that node is of type System.__ComObject and I'm not sure how to progress.
Any help is appreciated.
It turns out I figured out how to fix this right after posting it here!
The problem was I was using the "var" keyword in second loop, and casting the "file" variable to "ProjectItem" work just like first loop.
I am trying to perform a straighforward update using LinqToSQL, and just cannot get it to work.
Here's the data model: there is a timesheet_entry and customer. One customer has many timesheet_entries. It's a simple foreign key relationship.
If I'm editing an existing timesheet_entry, I get an exception if I change the customer_id.
Here's my attempt at the code. Can someone help me out here?
internal void CommitChangesToEntry(Timesheet_Entry entry)
{
Timesheet_Entry latest = (from e
in m_dataContext.Timesheet_Entries
where e.Timesheet_Entry_ID == entry.Timesheet_Entry_ID
select e).First();
latest.Entry_Start_DateTime = entry.Entry_Start_DateTime;
latest.Entry_End_DateTime = entry.Entry_End_DateTime;
latest.Task_Description = entry.Task_Description;
// Comment out this line of code and it
// doesn't throw an exception
latest.Customer_ID = entry.Customer_ID;
m_dataContext.SubmitChanges(); // This throws a NotSupportedException
}
The error is: "An attempt has been made to attach or add an entity that is not new, perhaps having been loaded from another DataContext. This is not supported".
Do you have any reason for not using the Attach method? Like the following:
m_dataContext.Timesheet_Entries.Attach(entry);
m_dataContext.SubmitChanges();
