Xpages - Custom property using method binding option is not showing the content - xpages

I have a custom control with around 20 custom properties. However, some of these properties need to contain code logic. This is fine, as I create the property as Type: javax.faces.el.MethodBinding and Editor: Method Binding Editor which works fine.
However, once I close the editor, click somewhere else, then click back to the custom properties of my custom control, the code has disappeared. If I look at the source code however, the logic is visible. Its a little frustrating, as whenever I want to use the editor, I need to copy my code from the source and paste back into the editor (to help with formatting, showing errors as I type etc)
Has anyone else come across this and know how to fix it, or is this just another quirk of designer?

How to hide URL Selector content tab?

I am creating a custom webpart using the Url Selector from kentico. I want the user to select content just from the Media Library. I went to form controls -> Url Selector -> Properties -> Dialogs_Content_Hide -> Default Value -> Yes and it still showing it in the Web Part. If I select the Dialogs_Web_Hide, Dialogs_Libraries_Hide and select the yes option in the default values, they hide, all except the Content_Dialogs.
Is this a bug? Or its something wrong?
Here is an example of the tabs
First set the form controls properties back to the way they were. If you don't, it will cause all kinds of problems later on.
Secondly, when you create the property in the webpart in the UI, select the URL selector form control for your text fields control. The scroll down just a bit and under the Editing Control Settings you'll see an "Configure" link. Click it. In there you will be able to tell the form control what tabs you want to enable and disable.
To add to Brenden's answer; if this is something you need to do a lot for your current build, then I'd also suggest making a copy of the Url selector form control and customize the properties as you originally mentioned. This way, you leave the default control in place for the system and have a control tailored to your needs. I've done this just now to check with a new form control that I called Media URL selector. Do make sure that you select the same source file as the original control in the Cloned form control file name property - Kentico by default will try to locate a new file called <original filename>_1.ascx. The reason for this is that admin section of your site also makes use of this control, so you may cause a nasty side effect somewhere else in the system.
As for why the settings had no effect; these are the default values you are setting. If you already have the form control in use, then the default setting would have been applied as they originally were. If you find one of the fields in question, you can change the control type to Text box, click Save, and then reassign it to Media URL selector.

Proper Kentico object for non-user-editable block of static html/javascript

The Situation: I've got a mid-sized chunk of html/javascript that contains an authentication script/input (it's a text input, radio control, and a combo box and a few buttons). What it is is less important than the concept that it's a mass of static client side code that the marketing department can pretty easily accidentally the whole thing.
The Desire: I want the users to be able to add it as a whole to a page, but not be able to modify it. When something needs to change, I want to change it in one place and have it be changed on all the pages.
What I've Tried: Widget with a default text. It works, but feels wrong. Users can edit it, and if they do when I fix it one place it doesn't propagate to all the instances. I'm a bit of a Kentico noob, but it seems like there should be a better way to do this.
Also note: I'm using portal engine if that makes a difference.
A widget is the proper usage. What you make your widget inherit from is the key in this case. I'd suggest creating a new widget based on a static HTML webpart. This way you can set the static HTML markup and hide the property from the content editor on the front end. You can do this by going to the Properties tab of the widget and setting the visibility of the field on the form. Don't delete the field, just hide it. It should be a checkbox that says hide on public form or editing form.
** Edit **
As I read through my answer and comments, I realized I meant to say clone the static HTML webpart and set its default text to your javascript. Then create a widget based on that cloned webpart. The text will reside in the web part and will allow you to update it in one place later, if needed.
I will not do it this way because you will be not able to make changes in the future. You can better create a new webpart this can be an empty webpart and then create a custom layout. In this layout you can put you're code. In this way you can always change you're code in the future and then it will be changed on all the places where the widget is placed.
I'd use a new widget based on the Static HTML webpart (make the field read only or hide it as Brenden mentioned), but store the data in a new custom setting.
no coding needed (only a macro to read the custom setting)
able to edit the script on the fly on any instance in the settings module. If you have multiple of these settings you won't need to go through all kinds of widgets to adjust their default setting but find them on a central place.
Cheers!

In this case I think it makes sense to create a custom web part to store all your code in it and use it that way. If you want to achieve it without creating a custom web part, you have to store the code in some non-web part and not widget specific object. I like the suggestion of creating a custom setting. You can then access this custom setting via a macro. This macro can be used as a default property of a newly created web part (inherited e.g. from the static text web part, you'd use the text property). You may as well create a widget out of it. Another approach is to use Kentico localization keys as a workaround. you can create a key in the Localization application and access it again, via a macro, e.g. {?customkey.myhtml?}. The approach with a custom setting however sounds cleaner to me.
This syntax should be working to access a custom setting value via macro:
{%Settings.CustomSettings.xxx%}
{%Settings.CustomSettings["xxx"]%}
{%Settings.CustomSettings.GetValue("xxx")%}

Command Not Handled Exception

I'm new to Domino Designer. I'm trying to modify an existing application which is running on a remote server. I create a blank xPage and view in browser and it works. I add a label and view in browser and it works. I add a combo box and setup a data source for my xPage. The data source is in the current application and I'm using a view. I setup my combo to point to that data source and specify BindTo value. I view it in browser and I get Error 500 "HTTP Web Server: Command Not Handled Exception" I can open the view that I've used and see all the data in the view. I can even add, edit, and delete from the view.
Ideas... Thnxs in advance.
Additional Info. I've added a "View" from "Container Controls" and used the same data source and the same view and it also works in the browser.
The error being printed is:
javax.faces.el.PropertyNotFoundException: Error getting property 'CompanyName' from bean of type lotus.domino.local.View
com.sun.faces.el.PropertyResolverImpl.getValue(PropertyResolverImpl.java:119)

This was already answered in the comments, but I want to write a better answer.
The problem in this case is that a view data source is being used for editing a document. Directly, this is not a possibility, though there are a few great ways to get around this. The first way, and my favorite, is to use an inline form. I think the Extension Library Demo database offers a few great examples of how to go about doing this. One way is to use a tooltip dialog. Another way is an inline form. A repeater is used and for every row in the view, a hidden panel can be made which contains the document data source and all field which are required to be changeable. By clicking on a button or link, the panel is made visible. This is my favorite variant because it is simple, quick, and generally looks great.
Another way to go about this is to have a view data source only, but use scripts to retrieve the document and set the values in the background and then save and release. It all depends on what you are trying to achieve.
My main recommendation is to look at the ExtLib demo and take a look at what they are doing there.

How to overcome the error "The unknown namespace tag xe:applicationLayout cannot be used as a control."

I created a sort of template DB for my Xpages applications. It is not a true template, just a design I can grab code from to start a new Xpages db.
I copied over a cc and got this error:
"The unknown namespace tag xe:applicationLayout cannot be used as a control, as the namespace http://www.ibm.com/xsp/coreex is not known."
I tried to creating a new cc in the target db and just pasting the source in, still got that error. What does that error mean and how can I overcome it?
I mean, come on, I can't copy and past design elements from one db to another???
It means that you haven't enabled the ExtLib in the application's properties. If you do to the Xsp Properties (in 9.0+) or Application Properties (in ancient releases), you can enable the com.ibm.xsp.extlib.library library, assuming you have it installed.
There is an event that can be triggered when dropping a native control onto an XPage or Custom Control. That event is used to enable the library in Xsp Properties. It's also used to enable the relevant abbreviation (xe, xc etc) on the pages. The bottom line is copy and paste isn't that sophisticated!
And it's not exclusive to the Extension Library. Try copying and pasting a Custom Control to a brand new XPage and save it. It will give you virtually the same message, but this time saying "xc" is not bound.
You need to enable the Extension Library manually if you're copying a custom control across. Alternatively, you can just drag and drop any Extension Library control onto any page in the application, then delete it!
If you're copying source code from one XPage to another, if it includes anything other than an xp tag, you need to check the relevant xml namespace is specified in the xp:view tag. So in the case of copying source code for the application layout, also adding xmlns:xe="http://www.ibm.com/xsp/coreex" to the xp:view tag.
(This was too long an elaboration to just add as a comment to Jesse's answer, which I've up-voted)

Why is my fileDownload control showing the trashcan even in read mode?

This is a rather strange one I think, and I'm sure I made a mistake here myself:
in one of my applications I'm showing a fileDownload control bound to a Richtext field in my underlying NotesDocument. The control's properties a are set to Hide if no attachments, show size, type and created as well as allow delete. The control itself sits inside a custom control, being part of another custom control, similar to this:
Xpage.xsp
- ccContainer
- - ccInnerDoc
Document datasources for both the container and the "inner" doc are defined at the root of ccContainer and passed into the inner doc.
The inner doc's datasource is comnputed based on a document selection, and it's igenoreRequestParams property is set to false so that I can display the contents of the selected datasource in a given panel etc.
The selected doc is first opened in read mode, and I can set it to edit mode using a button.
Problem now is that my file download control always is showing the delete icon (trashcan) no matter which mode the doc is opened in. And it's not only the icon showing, it also pretends to work by asking me whether I really want to delete and then really removes the file attachment. Only that this change of course cannot be stored into the datasource because it's only open in read mode.
I'm sure that this behaviour is some side-effect of something else in my application (to a certain extent I rebuilt this in a plain new db and until now cannot reproduce it), but I'm at the end of my knowledge of what this could be.
Any hint of what could be causing this is more than welcome.
In place of #Frantisek Kossuth I answer this myself: see compute dynamically the allowDelete property of file download xpages
Thanks again, Frantisek!
