I use TXDataWebDataSet.Insert(); to insert records. First time go fine.. at second time i have :
Cannot set property 'data' of undefined at Object.InternalInitRecord ....
heppen if i close and reopen dataset with persistent fields in it . ..
If i do :
//wdGraf.Close(); // il close da errore : Cannot set property 'data' of undefined at Object.InternalInitRecord ....
else if i do :
While Not wdGraf.IsEmpty() Do wdGraf.Delete(); GO FINE !
Please provide a sample project we can compile and reproduce the problem here. Hard to guess what's going on.
