UserRoles in ACL takes forever to apply in Xpages

Posted by on 19 January,2011 2 comments

I have tried a simple test I have a user direct in the ACL. The acl has two roles

User and Admin.
In the XPage I have a button that has a hide when formula that looks like this
if(context.getUser().getRoles().contains(‘[Admin]’)){
return true;
}
return false;
I have also tried
database.queryAccessRoles(@UserName())
But it also have the same effect this takes forever to apply If I add the Admin role to a user.
But if I have a notes form with a field and in that field I add @UserRoles
I just have to reload the form and the new user role apply.

I have tried using show nlcache reset ( tip from Erik Brooks) but it has no effect.

If anybody have an idea how to make the acl change apply also in XPages please feel free to comment.

Strange Error, Domino view doesn’t return any documents on webb but from client (Update)

Posted by on 12 January,2011 No comments

>The problem is now solved and the problem was that the ACL for the database was probably corrupt.

I copied the ACL to another database, changed one entry and copied the acl back to the original database.
Problem solved.
But it was strange

>I encountered a strange error today, running web application on a 8.02 server.

Some of the webpages stopped returning documents in some views.
just No documents found
And there is several databases using the same template some are working and some isn’t.
tried to fixup, updall -r but no luck
The only error that I have seen on the server is
Attempt to perform folder operation on non-folder note
But I don’t know if this is related. And I can see the documents in the view if I open the view from a notes client.

If anybody have an idea please send me an comment.

>are your code affected by the 8.5.2 computewithform bug and how to fix it

Posted by on 5 January,2011 2 comments

>There is a bug in Domino 8.5.2 that affects the use of Computewithform. If you are using computewithform in your code you should read this. There is no alarm because there is a easy fix to the problem and I don’t think that many will be affected. IBM is working on a HotFix for this but it’s easy to fix so that many will not need it.

If you use computewithform directly after you have fetched a document object then you are affected but If you do something with the backend document before you do the computewithform.
there is no problem.
So check if you application is affected search the code for computewithform( and check if you do a replaceitemvalue, getitemvalue or other manipulation with the document.
But if your code look like this
set doc=db.getdocumentbyunid(UNID)
Call doc.computewithform(false,false)
Then just change the code to
set doc=db.getdocumentbyunid(UNID)
Call doc.replaceitemvalue(“Form”,doc.getitemvalue(“Form”))
Call doc.computewithform(false,false)
And you have fixed the bug so simple.

You could store templates inside a nsf and use them using a special richtext light type.

Or if there existed a special xpage control for this. Thighter integration between lotus notes and Symphony is needed to get a larger customer base.BlogBooster-The most productive way for mobile blogging. BlogBooster is a multi-service blog editor for iPhone, Android, WebOs and your desktop

Mailto links with attachments

Posted by on 3 December,2010 No comments

>I tried this several times but with no luck.

the ordinary syntax for mailto links is like a ordinary url
first parameter starts with a ? next parameter and so with & nothing complicated here
mailto:emailadress
creates a new email with the default client
mailto:emailadress?subject=My email
Created a new email and the subject is my Email
mailto:emailadress?subject=My email&body=some text
Same as above but with “some text” in the body field
mailto:emailadress?subject=My email&body=some text&attach=c:\tempfile.txt
Same as above but you will also automatic attach the file tempfile.txt
most of the examples that is shown on the net is for outlook and they use another parameter name &attachments= this doesn’t work with Lotus Notes
You can also use cc and bcc to add people in these fields automatically.

>The return of the Notes Workspace, thanks Apple

Posted by on 26 November,2010 3 comments

>I had a discussion with a colleague about the simillarity of the Notes workspace and the IPhone / IPad homescreen layout.

If the Notes clients icons would be over the hole icon instead of at the top left corner, and you would add some shading and glossy by it self to the image.
If the background of the workspace would be a high def image and the user could change it by them self.
The Notes Workspace would be a design the users would feel like something new and fresh like the IPhone but it will be the same old workspace.
Then the Icons and the background could look something like this, What a difference…

>HTML 5 Canvas and .toDataURL

Posted by on 27 October,2010 No comments

>the Canvas object in HTML 5 contains alot of great things

one of the interesting things is that it has a implemented method to get the data inside the canvas as a base64 encoded string.
So if you would
var img1=new Image();
img1.src=”Image1.jpeg”;
var img2=new Image();
img2.src=”Image2.jpeg”;
var canvas=document.createElement(‘canvas’);
canvas.width=300;
canvas.height=300;
var canvas2d=canvas.getContext(“2d”);
canvas2d.drawImage(img1,0,0);
canvas2d.drawImage(img2,100,100);
var data=canvas.toDataURL();

Data will now contain a png image with both the images.
Encoded using base64 easy to send using ajax or store in a field.
You can draw images, plot dots, draw lines, boxes.

There is some online painting sites that already is using this.

>Can’t imagine that any other system is this simple when upgrading

Posted by on 3 October,2010 2 comments

>Upgrading from Domino 8.5.1 with Traveler to 8.5.2 with traveler no problem

and it takes no time.

1. I copied the installation files to the server 3 files
Domino 8.5.2
Traveler 8.5.2
Domino HF for SMTP
2. Shutdown the domino services
3. Started installation files for Domino
4. Started installation file for Hotfix
5. Started installation for Traveler
6. Started domino services again
Total time of upgrade max 15 minutes, bet that Microsoft if you can!!!
Of course we need to upgrade mailboxes but that can be done later no need for that
directly.
And there might be some other problems with your server but this server was straight forward no problem 😉

XPages Event parameters solution found

Posted by on 17 September,2010 No comments

>It’s very interesting that event parameters retrieval is totally undocumented and there is no articles / blogentries about it on the web. You should know that I have been searching and trying to get the solution thru the community but with no luck.

 
But Now I have found the solution
 
When triggering a onClick event the this object will contain a XspEventHandler and
this object has a method called getParameters() this method will return a Java ArrayList.
The arraylist will contain the parameters with name and value.
So to print all parameters you can walk thru them like this
 
var value=this.getParameters();
var tmp=””;

for(x=0;x

tmp+=value.get(x).getName()+” – “+value.get(x).getValue();
}
 
tmp will then contain a string will all the names and data of the event parameters for you to display.
