How to return values from a callServer

Hello all,

Using TeamSite 6.5 sol. What I want to achieve is to save the DCR automatically for the user in a subdirectory in the data folder which has less 500 DCRs under it. The subdirectories under data were created before. The structure is as follows (the numbers inside the parenthesis are the number of files under the subdirectories):
data
data1 (502)
data2 (504)
data3 (388)
data4 (0)
data5 (0)
data6 (0)
data7 (0)
data8 (0)
In this case, I want to save the created DCRs to data3.

My approach is to use a callServer and a server-side script to get the desired subdirectory’s name in the onSaveDone handler. Then I can use this subdirectory’s name to set the DCR’s name (IWDCRInfo.setDCRName(dcrName)). However, the callServer doesn’t return any value and besides the DCR is not constructed yet and I cannot set any value for this DCR.

Is there any way to pass the subdirectory's name to the javascript? Can I set the DCR's name in my callServer function? Please help.

You have access to all FormAPI functions and variables very easily from your callserver by invoking the following Javascript&colon;

var api = parent.getScriptFrame();

From this, you can get just about any information you want about the DCR. Use Perl to determine which directory to save to (to verify which directory has fewer than 500 files in it, etc.) but since callServer is executed asynchronously, you may want to invoke it from an onSave function. I'm not sure of the timing of this but assuming that your DCR has been saved by the time it gets to a certain point in your callSever (and it most likely would be), use Perl to verify that it exists and then move the file from the "data" directory to the appropriate sibling directory which has fewer than 500 files.

You should be able to block the actual save until you've determined the path and explicitly set the DCR name. I would strongly advise against moving the DCR after it's been saved since any generated files (a generate action will require saving of the DCR first) will have EAs associated with the name and location of the DCR.

Note - this is assuming that the 'name' of the DCR is pre-determined programmatically as well, either based on some field of input or some other mechanism.

The other method that I like to use is to use a workflow to drive the content creation - prompt for all the information you need about the name / type / etc of the DCR - create it programmatically where you want it and then fire off an Edit DCR session for the user to fill it in (and then do whatever else you want to do after that's been accomplished).

How do you block the actual save?

Thanks

Hi,

What you want to do is to catch the onSave event. In this function you make your callServer and return false (returning false stops the save process).
Now when your callServer script finishes it invokes a function again on the dct/dcr (parent.getScriptFrame().yourfunctioname() Smiley Wink

. This function starts by setting the dcrsavepath etc. and in the end does a IWDatacapture.save() (which will not re-invoke your onSave event).
This should work for you :-).
