John,

Once you compute the categorized view column you lose the expand/collapse. To get it back switch to the all properties view of the view column and add the column name back to the columnName property under the basics section.

If it's a view column you should get the expand collapse back. Not sure about the sorting but working on it.

Do you know where i can find the current page?
How about the number of pages available?

I went through the list of methods and didn't see anything.

Great find!

I posted something on the Domino 8.5 forum, not too long ago, looking for a solution like this. I need to reset the view/pager to the first page when the filtering changed.

Very clever, how do you come up with this stuff?

Great work once again, i really enjoy your articles.

Thanks John for another excellent tool. I'm sure it will get plenty of use.

@1, thanks Frank. The xpageName is used to identify what XPage you want to open the document in. I use it when building the href link for the view column to read/edit the document.

The parameters are documented in the OpenNTF.org project.

Nice work.
1 question, for what purpose is the parameter 'xpageName'??

@8. Martin, I'm almost done with it and will be posting it on OpenNTF soon.

It would be great if you could make that custom control available on openNTF

@14. Karthick, you want to use the getComponent() global function to access field values on the XPage by their ID. So try this instead: getComponent("FIELD_STANDARD_CONVENTION_1").getValue())

Hi,

I am working on XPages to get it displayed in 8.5.1 Notes Client and am able to view my xpages on the client. I created a button and an edit box by the names, BUTTON_STANDARD_CONVENTION_1 and FIELD_STANDARD_CONVENTION_1.

I have put the following code on my button (Client side script)

var fieldVal='#{javascript:document.getItemValue("FIELD_STANDARD_CONVENTION_1")}';
alert(fieldVal);

When I save and preview the XPage on notes client in 8.5.1, I get the following error message..

Unexpected runtime error
The runtime has encountered an unexpected error.

500 Exception
Error while executing JavaScript action expression
Script interpreter error, line=1, col=10: Reference error: 'document' not found
Reference error: 'document' not found

Can you help me resolve this issue,
Thanks in advance

perhaps a good thing to say is that you have to have 8.5.1 software installed, so for a quick peek or evaluation without installation this course does not allow.

don't aks me why

@12, Brendan. Take a look at this post I wrote and see if it does what you need. It uses a scriptblock control to trigger client JS when a session veriable is set in serverside JS.

Hi John, I was wondering if you had any idea of a good way to inject client-side javascript into a server-side call.

Case in point, I have a dialog which is created by jQuery which interacts with XPages via a series of hidden XPages controls. What I want to happen is when I click the "Save" (for example) button, validation occurs in the server-side javascript and it sets a requestScope variable with any errors, or if no errors are encountered it redirects to another page. If errors are encountered then a panel is displayed (using a combination of , the rendered attribute and a requestScope variable).

As you may be aware, you cannot redirect a page (using context.redirectTo*()) in an AJAX call.

My work around at the moment is to have a jQuery timer watching and waiting for an element to appear that is shown in a similar manner to how I display the errors. When the element appears in the DOM I use client-side javascript to redirect the browser to a new location.

This solution I find to be absolutely horrible. I know (coming from an ASP.NET background) that there is a way to have javascript fire from returned AJAX calls (using System.Web.UI.Page.RegisterStartupScript in ASP.NET. Irrelevant to the current situation but it may come in useful for other developers).

Holy Crap that's great info!!!

Could you dynamically create other stuff in a xpage
Like Hotpots on a image?

Comment From Steve Smillie

Steve Smillie — Fri, 29 Jan 2010 12:54:46 PM -0700

Just like @1, I had the same thought and I even asked that question on the 8.5 Beta forum long ago.
The answer was one XPages per view.

When converting existing Domino apps that used a $$ViewTemplate to XPages, you replaced one form with many XPages/Custom Controls.

I like the idea @1 of expanding that custom control by pulling from some database config.

I definitely would have interest in a custom control like your working on.

@5, Mark that's an interesting idea. Calculate all columns in a view plus the datasource. I guess I could set 10 columns and hide the additional ones that have no field assigned. I'll test that out...thanks!

John

Comment From Mark Hughes

Mark Hughes — Fri, 29 Jan 2010 08:13:52 AM -0700

why not just have a computed view data source, and compute based on scope variables, column values, hide when and stuff like that? I guess that is in a sense what you are doing anyway.

Comment From John Mackey

John Mackey — Fri, 29 Jan 2010 05:07:00 AM -0700

Thanks for your comments.

@3, that's just a limit on my demo and the checkbox selection I use. You actually list the fields in the order you want and pass them separated with ";". Example: customername;address;phone

@1, it does use the sorted order of the view you selected. I'd like to offer the user a clickable title. I guess to build on your point, I could switch views when the user clicks on a column.

@2, I am curious to see how you incorporate the $$ViewTemplate

Comment From John Turnbow

John Turnbow — Fri, 29 Jan 2010 04:35:23 AM -0700

Very nice.. I think there would be a need to choose where each field shows up in the view as well, not just select. I would like the Customer Name to be in the first column but could not move it there. Do that and you've got a great control.

Steve Castledine — Fri, 29 Jan 2010 04:25:56 AM -0700

I do have a custom control that you just give the viewname to and it builds the view ala $$ViewTemplate - just needs some finishing off which I will do very soon and then upload to OpenNTF. It uses existing view design properties as well to determine whether to show columns or not

Comment From Paul Withers

Paul Withers — Fri, 29 Jan 2010 04:21:07 AM -0700

One of my frustrations with XPages v classic notes-for-web development is that XPages is intended to separate data from presentation. With classic notes-for-web development, you can have one $$ViewTemplate (or one for multiple views). However, with XPages, if you're showing views with different columns or columns in a different order, you need separate custom controls. This is a great idea for allowing user flexibility but could also be extended to pull from a database config, one of the ideas I've not had a suitable project to pursue.

For sorting, can you use the sortColumn and sortOrder properties of the DominoView? The problem is I've never been able to work out or find examples to see what values these properties expect to receive. The other problem is I think you would need to enable sorting on all columns in your Notes View, which could have performance impacts.

An alternative would be to have copies of the views sorted on the different columns, and switch the view based upon which column they want to sort (e.g. if sort is City, switch to a view myViewCitySort instead of myView)

@Chris, try opening the db in designer and doing a project - clean. This will recompile the XPages. The db was compiled with the 8.5 code stream. That's the first place I would look.

Hi John

Thank you for a great looking sample application in your survey tool. I have loaded it onto a 8.5.1 server and when following through any links I get the following error message
Error 500
HTTP Web Server: Command Not Handled Exception

I did sign the database - though I am on a DDN server so could not get access to check the server configurations

Here's a link to the database on the server
{ Link }

Any ideas of thoughts?

Thanks again

Chris

@Nathan. You can look at the source for the computed value for a combobox control and use that as a guideline. I understand that they will be adding in the interface for both radio buttons group control and checkbox group control in one of the next releases.

Here's an example of the computed values for a checkbox group control taken from my survey tool example. Look at the value for this tag "":

value="#{SurveyQuestion.Answer}" layout="pageDirection">
return type=="CheckBox";}]]>
return req=="Yes";}]]>

return @Explode(choices,",");}]]>

Can you perhaps give an example on how to compute the values for the checkbox group and radiobutton group controls?

Comment From Ketil

Ketil — Fri, 1 Jan 2010 02:31:46 AM -0700

You could also just put the javascript between to script tags in your xPage or custom control. That will also do the trick. I did that in 8.5.1
