Title: passing parameters to xsp files

Hi Carolien,

I guess you want something like this .....

(I did it in plain xml/xsl, didn't find the time to use cocoon on this one, but it's a working sample.

Where I use the document function in XSL, you should put the values you cincluded ....)

I made 2 xml files (BillGates.xml and JenniferLopez.xml)

I have one file to fill the comboboxes with the "Gender" attribute.

I then transform the files into HTML using the fourth file, the Client.xsl.

As you will see, the genders are depicted correctly for both (as far as I know)

The code that really does it is this ...

I think this will solve your problem, as your comboboxes are put on the value they already had ....

Regards,

Yves Vindevogel

Subject: passing parameters to xsp files

Hi,

Currently I'm working on a web application that uses an Oracle 8i database, Cocoon 2.0, Tomcat 4.1 and Apache 2.0. I'm using XSP to query, insert and update my database.

Now I stumbled upon the following problem. I've searched the web for answers, but even Google wasn't able to help me. So you guys and girls are my last hope. ;-)

Using XSP want to update a table in my database. So far, no problems. This is the relevant section in the sitemap:


        <map:match pattern="update/*.xml">
                <map:generate type="xsp" src=""/>
                <map:transform src=""/>
                <map:transform type="cinclude"/>
                <map:serialize type="html"/>
        </map:match>
        
        <map:match pattern="form/update-application">
                <map:act type="form-validator">
                        <map:parameter name="descriptor" value="context:///DIS/database/validate/insert-application.xml"/>

                        <map:parameter name="validate-set" value="insert-application"/>
                        
                        <map:generate type="xsp" src=""/>
                        <map:transform src=""/>
                        <map:serialize type="html"/>
                </map:act>
                
                <map:read src="" mime-type="text/html"/>
        </map:match>
        <map:match pattern="include/owner.xml">
                <map:generate type="xsp" src=""/>
                <map:transform src=""/>
                <map:serialize type="html"/>
        </map:match>

I've also attached the relevant xslt and xsp files.

As you can see, I include the transformed owner.xsp file in my application.xsp file. I do this, because I want my users to have a drop down box with them showing all the possible foreign keys. This way they can never make a mistake updating foreign keys in the database.

This all works fine, updating and everything. Except for this: I want the right foreign key selected in my form. I cannot expect my users to select the right owner in the drop down box everytime they do an update. So I want to tell the owner.xsp file the owner_id of the application.xsp file that includes it. A simple test in the owner.xslt should then do the trick. I know it is possible to pass parameters through the sitemap, but in this case I want the contents of my parameter to be dependent on the contents of my xsp file. I don't know how to do this. I don't even know if I'm thinking in the right direction.

Can you please help me on this? Thanks!
