DCR Compatibility

Hi all,
I've got a problem with a TeamSite form.

The customer is asking to modify a TeamSite form adding a new container.

I know that old DCRs won't work fine if I modify the form in this way.

Is there a way to have a "backward compatibility" with the old DCT format for the old DCRs?

Thank you very much for your help.

Best regards.

Do you mean existing dcrs by old dcrs ? if yes, then the item(s) enclosed by the new container will lose their values.
If not, then please explain a bit more on requirement.

Yes, I mean the existing DCRs.

I would like to maintain the original values.

Is there a way to achieve this?

Are there only few such dcrs, then you can manually download them and add the container around the item(s) ? Be careful in putting correct index values for the container.
If the number of such dcrs are many, then another way, out would be to write a .ipl script, which will just place the container element in the dcr by editing the dcr as xml file,saving them and submitting them.
Prior to this make necessary changes in the datacapture.cfg file.

We have faced similar things before.The way we went resolving this is to use a perl script to change the XMLs(DCRs).having the script for this offers the advantage of reusing it for such future requests also.

Your description is a bit vague - is the container to be added completely new, including its contents - essentially tacking it on to the existing DCT structure - or is this a container that is going to surround / include pre-existing fields?

For the former - it should be relatively easy - existing DCRs when edited will start with this new container's fields being empty and all pre-existing fields populated. You will need to update your PTs to process the new fields, and you may need to add more FormAPI code - but that shouldn't be too hard.

For the latter - you need to process all your existing DCRs and PTs, and possibly FormAPI code - to inject the container element (and any new fields within it) in the proper place within the structure of the pre-existing files.

For DCRs you can use a number of approaches - including XML parsing and regex's and such. For the PT's and FormAPI you can do a bunch of it with regex's - but you'll have to re-test everything as sometimes the directives are coded in a less-than-optimal manner for such modifications. E.g.:

function foo(item) {
    var xitem = item.getName().replace(/y$/, "x");
    ...
}

might have to become:

function foo(item) {
    var xitem = item.getName().repalce(/y$/, "z/x");
    ...
}

and that's only one example.

In either case - if you are deploying content fields to a DB using DataDeploy - you will have to deal with changes to the dbschema and may have to drop/re-create the tables to which you were deploying.

Thank you all for your suggestions.

- Ghoti: we must add a new container that is going to surround pre-existing fields.

We are building a new perl code to modify the existing DCRs.

As indicated, it can be done - but you have to remember it's not just the existing DCRs that have to change, it's:

and making a "game plan" so you have some idea of what you need to work on and what you need to test afterwards.
