Clear Document Attribute?

bkonia

Is there any way to programatically clear a document attribute, so that it no longer contains the document? I tried setting it to UNDEFINED, but Aware IM interpreted UNDEFINED as the name of a document template.

Not from rules. You can do it from a Java plug-in only at the moment.

I discovered that you can have an document type attribute like SystemSettings.DocUndefined that you just leave undefined.

Then use the rule BO.DocAttribute=SystemSettings.DocUndefined to clear a document from BO.DocAttribute.

I have the same task to solve, Aware IM 5.0 Build 1416
I would like to use an rule within a BO to clear the document attribute to empty.

Business Object: motorcycle_contract
Attribute: MotorcycleContractDocument

The following rule does not work: motorcycle_contract.MotorcycleContractDocument=SystemSettings.DocUndefined

How can I clear/delete the content of a docment attribute?

tford

Hi Marc,

...=SystemSettings.DocUndefined

Still works for me. Are you sure your SystemSettings BO is initialized?

2- You can also use ...=UNDEFINED

This was a new addition to a build a while ago.

Hi Tom,

thanks for your reply, my rule looks now like this:

If motorcycle_contract.delete_forms WAS CHANGED TO 'Yes' Then
motorcycle_contract.MotorcycleContractDocument=UNDEFINED
motorcycle_contract.motorcycle_evidence_of_ownership=UNDEFINED
motorcycle_contract.motorcycle_nova_confirmation=UNDEFINED
motorcycle_contract.motorcycle_takeover_confirmation=UNDEFINED
motorcycle_contract.delete_forms='No'

Option: Dynamic re-calculation = YES

The rule works now on clicking save but the docments are not new created on clicking the save button.

Hi Marc,

... but the docments are not new created on clicking the save button.

Not sure what you mean by this & what you are still trying to achieve.

marc

Hi Tom,

the target is that in a BO multiple documents are created on save.
If data in the form will be changed it is nessesary to recreated the documents.
For this reason i think i need to delete the documents and recreate them on clicking the save button of the form.

tford

Marc,

I think I understand now.

Assuming motorcycle_contract.delete_forms is a Yes/No attribute, change it to "Save form when checkbox ticked or unticked".

You can then remove the dynamic calculation from the rule. Checking this box will save the form & cause the rule to fire.

I think you might also want to change motorcycle_contract.delete_forms back to "No" when the form is saved & this rule fires.

Tom,

I have removed the Option: Dynamic re-calculation now.
The dokuments are removed now on save but the documents are not recreated on clicking save again, the only option is now to upload forms from the harddrive.

tford

... but the documents are not recreated on clicking save again, the only option is now to upload forms from the harddrive

I don't understand where they would be "recreated" from.

Once they are set to UNDEFINED by the rule, I thought you wanted the user to upload new forms.

marc

No the documents are automatically created based on the form data the user enters.
The documents are then stored as PDFs and will be used to do the printout on the client side.
If the user changes something within the form the data in the documents needs to be updated.
As the PDF documents are not updated automatically my thinking was to the delete them first and recreate them by a rule.

tford

OK. Is there something you still need help with?

marc

Tom, I think it's hard to describe but I try to summarize.

I have a BO where attributes are defined as documents and the inital value of these attributes are Document Templates (Report, PDF).
When the user filles the form and saves the form the documents are created on SAVE.
The reason for that is that the user shall open the PDFs to download them or use them for printing.
The problem now is: When the user changes data in the form the documents needs to be recreated to get the updates also in the Report PDFs.

tford

No need to go through the delete process you initially asked about.

Just recreate the documents:

If motorcycle_contract.delete_forms WAS CHANGED TO 'Yes' Then
motorcycle_contract.MotorcycleContractDocument='ContractTemplate'
motorcycle_contract.motorcycle_evidence_of_ownership='EvidenceTemplate'
motorcycle_contract.motorcycle_nova_confirmation='NovaTemplate'
motorcycle_contract.motorcycle_takeover_confirmation='TakeoverTemplate'
motorcycle_contract.delete_forms='No'

In fact, you probably do not need the motorcycle_contract.delete_forms attribute. Simply monitor if the form data changes & fire the rule above.

Tom,

this works, Thank You!!!
