Hi, all

1, I created the attribute ATTR1 under the NODE1 which the cardinality is 0...N.

2. I created the a TEXTVIEW element named TV1 and then bind it to ATTR1.

I did the step 3 respectively under the following steps.

3a. I ran the program. and an exception was raised, ' Access via 'NULL' object reference not possible. '

3b. I gave the ATTR1 some value by using the wizard in method WDDOINIT,

however, it also raised the same error ' Access via 'NULL' object reference not possible. '

and finally, I changed the cardinality from 0...n to 1...n. and then it got correct..

can somebody tell me why??

thanks in advance 😊.
