custom Collection (DAM)

svukovic

Hi!

I'm trying to set custom attributes as a column in Collection. I try with adding

<attribute>attribute_name</attribute>

<attribute_type>String</attribute_type>

<content_attribute>false</content_attribute>

<label>attribute label</label>

<visible>false</visible>

</column>

<columns> in a dam_collection_component.xml and the attributes

are displayed in Collection "display settings" on a "Select attributes

to display:". When I chose attribute to be displayed(move him to

"Selected attributes to display as column:" list) and click ok the

error message are prompt:

*Error creating the collection table

result set : error: "You have specified an

invalid attribute name (attribute_name)."*

Same thing I did for folders and cabinets and all works fine.

Please help!

It seems that the custom attribute is not queried. Have you tried to put this custom attribute for querying? In your components onRender method get the datagrid, then get it's data provider, then add them, like:

DataProvider docListDataProvider = ((Datagrid)getControl(DocList.CONTROL_GRID, Datagrid.class)).getDataProvider();

String[] arrPrevAttrs = docListDataProvider.getCustomAttributesInQuery();

String[] arrNewAttrs = new String[http://arrPrevAttrs.length + 2|http://arrPrevAttrs.length + 2];

for (int i = 0; i < arrPrevAttrs.length; i++) {

arrNewAttrs+ = arrPrevAttrs+;

}

arrNewAttrs[http://arrPrevAttrs.length|http://arrPrevAttrs.length] = "your_custom_attr_1";

arrNewAttrs[http://arrPrevAttrs.length1|http://arrPrevAttrs.length1] = "your_custom_attr_2";

docListDataProvider.setCustomAttributesInQuery(arrNewAttrs);

It seems that putting it only into your component.xml, it does not put it in the query, only tries to display it.

Thnx mszurap for you replay!

My component extends com.documentum.dam.library.collection.Collection and in onRender method I can get Datagrid and his DataProvider but getCustomAttributesInQuery() always return null, also DataProvider .getQuery() always return null. I try to add only custom attributes in Query.

Datagrid grid = (Datagrid) getControl(

com.documentum.dam.library.collection.Collection_new.GRID_NAME,

com.documentum.web.form.control.databound.Datagrid.class);

System.out.println("getCustomAttributesInQuery:"

+ grid.getDataProvider().getCustomAttributesInQuery());

I get "null".

Set new query attributes:

String[] arrNewAttrs = new String[6];

arrNewAttrs[0] = "custom_attr_1";

arrNewAttrs[1] = "custom_attr_2";

arrNewAttrs[2] = "custom_attr_3";

arrNewAttrs[3] = "custom_attr_4";

arrNewAttrs[4] = "custom_attr_5";

arrNewAttrs[5] = "custom_attr_6";

grid.getDataProvider().setCustomAttributesInQuery(arrNewAttrs);

then I call getCustomAttributesInQuery() to see if my custom attributes are added:

String[] arr = grid.getDataProvider()

.getCustomAttributesInQuery();

for (int i = 0; i < arrPrevAttrs.length; i++) {

System.out.println("arr:" + arr+);

}

and get:

arr[0]:custom_attr_1

arr[1]:custom_attr_2

arr[2]:custom_attr_3

arr[3]:custom_attr_4

arr[4]:custom_attr_5

arr[5]:custom_attr_6

Now, when I add attribute to be displayed in "display settings" and click ok, I get :

An error has occurred.

class java.lang.NullPointerException

I can understand whay DataProvider.getCustomAttributesInQuery() returns null? Component is working fine with non custom attributers.

Sorry, I cannot help further in this deep level, I don't know DAM this well.

svukovic

Thnx for your effort anyway!

Any other ideas?

Hi!

My solution:

Create new class that extends Collection
Override "public void setQuery(String strQuery){..." method
Manually insert custom types into query
Redirect <class> in Collection component definition to new class

this solution works fine for me:)
