[phpsoa] Re: Unsetting of data objects using xpath not working as expected
Thank you for checking into it for me. I guess I'll loop through the results and remove when I find a match. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "phpsoa" group.

It is working as designed, but this does imply that the design is somewhat flawed. The xpath support was only specified to work with instances of SDO_DataObject. But $record->logicalPort is not an SDO_DataObject, it is an instance of SDO_List. The problem is apparent if you try to access a list element using an xpath. For example $do = $record->logicalPort['portId=24']; results in the oh-so-explanatory message: PHP Fatal error: main(): internal error (747) - invalid dimension type 6 in on line In other words, you are using a String (type==6) as an index into a list, but only Integers are valid. There's clearly a check missing somewhere, because when you do your unset, it just silently fails and doesn't present an error message. I'm not hopeful that Tuscany would want to add the function to access a list element using xpath, though I could ask. In the PHP implementation, we could at least fix both the baffling error message and the failure to output an error message when you attempt to unset a list element using xpath, though. As discussed, your best bet for now is to iterate through the list to find the index of the element you want to remove. Then unset it using the index as a numeric index.

It's interesting that your second example shows that the xpath is resolving correctly. What happens if you access the element more directly, something like $record->logicalPort[0] - can you unset the element that way? If you could provide a minimal testcase, I'll run it in the debugger and see what Tuscany is doing. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "phpsoa" group.
