Hi, I have the following issue

I successfully created and installed LL Attribute for Category using examples from the Attribute Package 1 v.1.0.0 for LiveLink 9.70
Also My Attibute can be selected in WorkFlow Attributes and also Forms
The main idea of my attribute is Auto Complete - an input field to enable users quickly finding and selecting some value, leveraging searching and filtering
The value passes to the LiveLink using AJAX from the input filed by OnPressKey event. Here is an example //set parametrs for Fieldname, pressed value, and attribute ID pars+="&fldname="+fieldname+"&pressedval="+val+"&aid="+attrid+"&VerNum=`verNum`&objid=`objID`";//call request handler getDBData url='?func=dmautocomplete.getDBData'; //Send url with param using Ajax request to return ComboBox with values i var myAjaxS = new Ajax.Updater( fieldname+'-content', encodeURI(url), { method: 'get', parameters: encodeURI(pars),requestHeaders:['If-Modified-Since', '0'],evalScripts:true });
But when I add the autocomplete attribute to WorkFlow in the Work flow Attributes, try to press any char on the keyboard, i get an error

Here is the Code from LLRequestHandler of my attribute

function Dynamic Execute( Dynamic ctxIn, Dynamic ctxOut, Record r )

Assocresult

DAPINODEnode

DAPIVERSIONversion

Dynamiccontent

Booleanok = TRUE

IntegercacheID = 0

ObjectprgCtx = .PrgSession()

if IsFeature( r, "CacheID" )

cacheID = Str.StringToInteger( r.CacheID )

if IsUndefined( cacheID )

cacheID = 0

end

if cacheID > 0

result = $LLIApi.CacheUtil.Load( prgCtx, cacheID )

if !result.OK

ok = FALSE

.fError = result.ErrMsg

else

content = result.ObjectValue

end

else

node = DAPI.GetNodeByID( prgCtx.DSession().fSession, DAPI.BY_DATAID, r.objid )

if IsError( node )

ok = FALSE

.fError = 'Error retrieving the definition.'

else

//Get the attribute valid values from the database.

version = DAPI.GetVersion( node, r.VerNum)

//Get the current version of the node.

if IsError( version )

ok = FALSE

.fError = 'Error retrieving a version of attributes definition.'

else

result = $LLIApi.LLNodeSubsystem.GetItem( node.pSubType ).NodeFetchVersion( node, version)

if !result.OK

ok = FALSE

.fError = result.ErrMsg

else

content = Assoc.CreateAssoc()

content.RootSet = result.Content

end

if ok

...........

I understand the issue, that I use VerNum and objId for LL Category, but I can find info how to make it is worked for Work Flows and Forms

How can I make that my attribute would work in WorkFlowsand Forms?

Could somebody help me, thanks a lot?

Hi,

If i uderstand your problem right, the issue is that workflow attributes do not have such a object like category. Attributes definition is a part of WF map.

Hi, thank you for your reply, You uderstood the issue correctly.

I took Atrribute package as example, created the Category Attribute, and my Auto Complete module works fine after to month of development . But .......

Then I tried to add the Attribute to WorkFlow and Forms, and it was installed successefully, but when I press any keybord button, it throws the error objId and version error, This happens because I get node id of partycular document (as it wast in Attribute package tutorial and examples) and it's category to get atrribute pressed value by AJAX. But the attribute doesn't work WorkFlows and Forms, there is no ObjId.

I am new at module development for LiveLink, thats's why I don't know how to make it works for WF and Forms, so I would be gratful for somebody's help.

Thanks a lot.

Hi,

Can you explain in few words why do you need definition id and version?

Do you need some information from attribute definition/configuration? If yes, and the amount of data is not large then it makse sense send configuration data as part of querystring.

Hi, I need the information from Attribute Value, the idea is that I have input text field,where user can enter any char from keybord, after the user get Combobox element with records from database that contain char "a"(for example)

A, aa, aa, ba, ccca .......

And when user save the category he chooses the record, for example, 'ba' in he same input text field, like a Google Search concept, but for any table in Live Link Tables.

I made my module using the example Attribute Package, thats why in the module I use objId and version, because first my task was to make it for LL Categoy . if there is any different methods how to make attributes for Category, Forms, and WorkFlows, it would be excelent to look at examples.

Thank you for you replay, I appriciate your help.

Hi,

There is no need to create extra category.

You have to create your own attribute type - orphan LLAttribute neede type, orphan webattribute. Implement necessary functionalities for your attribite.

And the trikcy part is that you have to register your attribute for categories, forms and workflows.

Add lines to your custom module Root:startup script

$LLIApi.LLAttributeSubsystem.AssociateTypesByCustomID( 0, { Your attr type ID} )
$LLIApi.LLAttributeSubsystem.AssociateTypesByCustomID( 2, { Your attr type ID } )
$LLIApi.LLAttributeSubsystem.AssociateTypesByCustomID( 3, { Your attr type ID} )
