passing client side objects to server could be possible only if there is any event happening that sends the object to the server. here the expression is already executed onto the server and rendered back to the client.

var someDate = new Date(2010,4,1);
var someVar = '#{javascript:sessionScope.put("sessDate",someDate);}';

regarding this example, one solution could be that you could assign the someDate value to a field of Date type and then try passing the field to sessionScope.put method. Reason being that fields are actually accessible on both the sides (server side as well as client side).

Also need to check if its possible to pass client side objects to server side script as you were trying in your example.

Hi John,

I figured out how to solve this "bug".
I put the object, that put the custom control as a "newDocument", in the end of the array.
disableTheme="true">

CodigoAN="#{javascript:entryExecutante.CodigoAN}"
CodigoGerencia="#{javascript:entryExecutante.CodigoGerencia}"
CodigoVCP="#{javascript:entryExecutante.CodigoVCP}"
Gerencia="#{javascript:entryExecutante.Gerencia}" NoteID="#{javascript:entryExecutante.NoteID}">

Hello John,
First, I like to congrat you for this nice article.
Now, get to the point:
I'am developing a web XPages application, and I trying to use your techinique of using multiple Datasources.

I gotta a main document that have 0 or more dependent documents. So, I desined a XPage with a repeat control that shows the associated documents:

The formula that Im using inside the repeat control is:

var index=0;
if(sessionScope.acaoVCP=="novoExecutante"){
arrayExecutante=new Array();
//arrayExecutante[index++]=sessionScope.dadosNovoExecutante;
arrayExecutante[index++]={
action: null,
NoteID: null,
CodigoGerencia: vcp.getValue("ca_vcpCodigoGerencia"),
CodigoVCP: vcp.getValue("ca_Codigo"),
Gerencia: vcp.getValue("ca_vcpGerencia"),
CodigoAN: vcp.getValue("ca_vcpCodigoAN")
}
}

var dc = viDu001.getAllDocumentsByKey("C~"+vcp.getValue("ca_Codigo")+"~fo_ExecutanteVCP~", false);
if(dc.getCount()>0){
if(arrayExecutante==null) arrayExecutante=new Array();
for(var i=1; i<=dc.getCount(); i++)
arrayExecutante[index++]={
NoteID: dc.getNthDocument(i).getNoteID(),
action: vcp.isEditable()?"editDocument":"openDocument",
CodigoGerencia: vcp.getValue("ca_vcpCodigoGerencia"),
CodigoVCP: vcp.getValue("ca_Codigo"),
Gerencia: vcp.getValue("ca_vcpGerencia"),
CodigoAN: vcp.getValue("ca_vcpCodigoAN")
};
}

return arrayExecutante;}]]>

Basically, this formula creates a array of objects that will initialize the custom control that contains the datasource of the associted doc.
At the beginning, I test if the user is creating a new document (sessionScope.acaoVCP=="novoExecutante", this sessionScope variable is set through a button), if so, it sets the first position on the array with a object with action=null and NoteID=null, signaling that the datasource correspond a new document.

The button that shows that signals the repeat to put the empty custom control at the beggining follows:

Note that the event only tells the application to refresh partial, the "pnExecutantesForm" is the that contains the button and the repeat control.

Inside the repeat, I put a custom control with a datasource to the associated document.

action="#{javascript:entryExecutante.action}"
CodigoAN="#{javascript:entryExecutante.CodigoAN}"
CodigoGerencia="#{javascript:entryExecutante.CodigoGerencia}"
CodigoVCP="#{javascript:entryExecutante.CodigoVCP}"
Gerencia="#{javascript:entryExecutante.Gerencia}"
NoteID="#{javascript:entryExecutante.NoteID}">

This custom control provides a few properties to allow me to control its behavior.
The custom control's Datasource is defined by the compositeData.action and the compositeData.NoteID:

formName="fo_ExecutanteVCP" ignoreRequestParams="true"
computeWithForm="onsave"
documentId="#{javascript:return compositeData.NoteID}"
action="#{javascript:compositeData.action}">

docNewExecutante.replaceItemValue("ca_exvCodigoGerencia", compositeData.CodigoGerencia);
docNewExecutante.replaceItemValue("ca_exvCodigoVCP", compositeData.CodigoVCP);
docNewExecutante.replaceItemValue("ca_Codigo", requestScope.CodigoNovoExecutante)}]]>

The main objective here is, allow the user to view the associated docs through this custom control in the main page, and, when the user clicks the button to add a new associated doc, the application shows in the first position a empty form to input the information.

THE PROBLEM:

When I click the button, instead of show a empty form, it shows a form whith the values of the last line of the associated docs, and scramble all the associated docs that it had already show in a correct way.
The strange thing is, when I put only the part of the code that put the object that intialize the custom control to show a empty form, it works. But, when I mixed up, it gets scramble.

Do you have any idea why this is happening?
Any help will be welcome.

Hi John:

I have a question about if is possible to control the files's size when it is upload, I did an example an upload a file with empty size ( 0 kb ) and when I submit the document permit me to do this, but when I open again the document in read mode is not attached because is deleted automaticcally ( same case for the documents greater than 1024 kb ), I would like to control this when the files is being upload. Do you have any axample about it ( if is possible to do it ) ? I really aprreciate your help.

Thanks in advance.

Hi,
It seem's that if you put your JS in a library, the syntaxe '{#}' don't work. Have you a way to bypass that?

Thanks

Hi, This is in continuation of the earlier issue that I reported. I was able to figure out what was causing the issue. In the location document, under Basics tab, I had proxy settings. The moment I remove that, XPages start working in notes client. Not sure why is this happening, and I can't afford to remove this proxy setting from each of my users. So, is there a work-around that anyone knows?

I stumbled upon this while looking for something else in your blog, and the comment by Vitalijs is precisely the solution I was looking for to dynamically load a custom control. Thanks to the both of you! John, I am most grateful -- your blog & examples are an indispensable resource to learning & using XPages.

gotoPage only seems to work if the page you are going to is a link on the pager. e.g. if the pager shows pages 1-8, gotoPage(10) will go to page 8.

I think you can find the current page from the pager.

e.g.
pager: com.ibm.xsp.component.xp.XspPager
repeat: com.ibm.xsp.component.xp.XspDataIterator

Hello,

Great article, thank you.

The only remaining question is, how to handle categorized views: e.g. on the first page I open three categories, then I open a document from the third opened category, which moved to the second page of the view by opening the categories. Closing the opened document takes back to the first page of the view instead of the second, because opened categories have not been stored.
I could not find any way to store the categories opened by the user, to make possible navigate back exactly the same position (view row) from the document was opened, with the categories opened. This currently works only in standard Notes client, unfortunately.
Opening Xpages documents in new window can be an option, however this method can not be applied to Notes client.
How to use gotoRow()? Totally agre with this question. From where should we get the parameter in this situation? By opening and closing categories the row number of the document always change.

Hi John,

Thank you for the tip,
Could you please tell me how do you do the same and even bind the computed field to a field in a form?
the field in your sample is like "computed for display" how can I do the same for a computed field stored in the database ?
Thank you in advance,

Hi,
Its a cool stuff and works fine on web. I placed the Customer orders database on a server and accessed it from few of my machines running Lotus notes 8.5.1. It worked fine in one machine, but it displayed the message "Loading Customer order..." for few minutes and then gave the error "Network Error A communication error occurred: 'Operation timed out' The Web server may be down, too busy, or experiencing other problems preventing it from responding to requests. You may wish to try again at a later time." Any idea of what could be the problem?

Hi,

I have the same problem as Sudatta. The code is in a library and it seems the server side code does not work there. Has anyone found a solution yet? Thanks.

Hi John,
This is very helpful. I followed all the steps and eventually things work fine for me.

When I attempted it the second time, I started facing the issue that was mentioned by Laura - the javaMethods package under the source which I create is forced under Local.

Proceeding further, creating the package and the java file under local, and dragging and dropping the same under the source folder works .

But is there any fix to this?... Am I missing some thing?

thanks,
Karthick

Comment From Sudatta

Sudatta — Wed, 14 Apr 2010 09:35:13 AM -0700

Hi,

I'm trying to execute server side javascript using client side javascript like the below example:

var test = '#{javascript: @DbName();}';
alert (test);

This works fine when i write this code under a button in an xpage in the client side tab.

However, here is the pain area :
I'm using a client side javascript library and included that in the xpage : and in that i'm trying to execute the code on the dojo onClick event using dojo.Connect but it does not execute the code and gives the alert as "'#{javascript: @DbName();}'" for the below code:

var test = '#{javascript: @DbName();}';
alert (test);

Please let me know if what needs to be done in order to make this work properly...

Thanks in advance for the help.
