DfTypedObjectException:: DM_API_E_BADATTRINDX

chenthil

Hello,
When i am trying to fetch the custom(attr_comment) attribute value,i am getting the following error message

Quote:

Exception Occured : DfTypedObjectException:: THREAD: http-9090-2; MSG: [DM_API_E_BADATTRINDX]error: "Attribute name attr_comment' for document/object has incorrect index '-1'"; ERRORCODE: 100; NEXT: null

Code:

IDfPersistentObject commentsObj = dfSession.getObject(tempCollection.getId("r_object_id"));
  reviewComments = commentsObj.getRepeatingString("attr_comment", commentsObj.getValueCount("attr_comment") - 1);

Please give me suggesstion to solve the issue.

Thanks

I just tried this on my 6.5SP2 installation.

If a repeating attribute has no values:

• obj.getRepeatingString("your_attr", obj.getValueCount("your_attr")) returns null
• obj.getRepeatingString("your_attr", obj.getValueCount("your_attr") - 1) throws the exception

The problem is that your asking the repeating string at location -1 if the repeating attribute does not have values.

Let's say your attribute has 0 values:

• obj.getValueCount("attr_comment") => 0

So if you do obj.getValueCount("attr_comment") - 1 you provide an invalid index.

This is how it is, although the DFC Javadoc says different things:

getRepeatingString
String getRepeatingString(String attributeName,
                          int valueIndex)
                          throws DfException

Returns a string value stored in a repeating attribute.

You can call this method on a single-valued attribute as long as valueIndex is 0. Note  that negative values are interpreted as 0. For example, passing -2 for valueIndex will  return the value at index 0.

Parameters:

attributeName - the name of  the repeating attribute

valueIndex - the index  position of the value among the values stored in the repeating                       attribute

Returns:

the string value

EDIT: little additon on adding/getting repeating attributes.

• adding an new value to a repeating attribute: obj.setRepeatingString("attr", getValueCount("attr"), "new value");

• getting all repeating values:
  
  for(int i = 0; i < obj.getValueCount("attr"); i++)
  {
  String attrValue = obj.getRepeatingString("attr", i);
  }
