Parent Table Restricted: Refetching Error

[[email protected]]

This one is strange. I have seen previous posts where there was a bug on the last record, but the only time I get this error is when I try to delete the very first record. I can always delete any other record, but never the first record. I had seen that there was a fix in ver 10, but I'm not sure if this applies as well to the deletion of the last record. It is an embedded browse

Also, maybe not related, but where I get an error's on checking field on the stock quantity thru the "can save" event logic, I lose the ability to enter new records or even delete the current one. Here's the code below, and maybe both problems are related:

if tbl.Qty_IN_STO - v_quantity < 0 then
msgbox("Quantity in StocK Cannot be Less Than Zero , Please Correct Qty or Delete Tool")
cancel()
tbl.close()
end
end if

Thanks for the eyes...Ryland

Re: Parent Table Restricted: Refetching Error

If this is the whole of your script, you probably don't want

tbl.close()


but then again, it can't be the whole script or tbl.Qty_IN_STO would be meaningless because the tbl pointer has not been established. A normal script would start with

tbl = table.current(#) 'some valid #, doesn't need/shouldn't be closed

or tbl = table.open("sometablename")

unless the tbl pointer is established somewhere else as shared or global (and v_quantity is established somewhere else as shared or global ).

Better tell us what is really happening.

Re: Parent Table Restricted: Refetching Error

Thanks Stan,

I've been unable to trace it down other than when certain conditions hit (like stock not available or certain due dates do not match), the browse does some werid things on the delete and new record add.

I commented out all of the code in the "can save" and "on save" events within the browse, and still get the same errors. The only thing I have not done is comment out the field rules to see if they are causing the browse 1st record delete problem.

Will try that, and if that produces no results, will post the files to see if ya'll see anything funny looking (other than myself).

Meanwhile here is the can save event code:


dim tbl as p
'Get 'Value' property of 'Browse1:Product_id' in Form 'Invoice_Issue' .
DIM GLOBAL v_quantity AS n
v_quantity = parentform:Browse1:Quantity.value
DIM GLOBAL v_product AS c
v_product = parentform:Browse1:Product_id.value

DIM GLOBAL v_type AS c
v_type = parentform:Browse1:tool_type.value


tbl = table.open("product",FILE_RW_SHARED)

'1st Pass for Product File Set the table order to the key expression
dim itbl as p
dim key_expr as c
key_expr = "Product_Id"
if key_expr = "" then
ui_msg_box("Error","Key expression cannot be blank. Edit the Action and specify the Key expression.")
end
end if
dim key_value as c
key_value = "" +a5_eval_expression("=Invoice_Items->Product_Id",local_variables())

itbl = tbl.order(key_expr,".t.")
'Determine the data type that the key expression returns
dim data_type as c
if tbl.eval_valid(key_expr) then
data_type = typeof(tbl.eval(key_expr))
else
ui_msg_box("Error","Key expression is not valid: '"+key_expr+"'",UI_STOP_SYMBOL)
tbl.close()
end
end if
find_result = tbl.fetch_find(convert_type(key_value,data_type))
'Was the find successful?
'Evaluate the key value for the current record and compare it with the key value that was searched for...
current_key = tbl.eval(key_expr)
if current_key <> key_value then
ui_msg_box("Error","Record to update not found. Could not find record with key value: '" + key_value+"'.",UI_STOP_SYMBOL)
tbl.close()

end if

Re: Parent Table Restricted: Refetching Error

This is the "ON Save" Event code in the browse:

'Open the table that you want to update...
dim tbl as p
tbl = table.open("invoice_items",FILE_RW_SHARED)
dim target_record as n
target_record = -1

'Since target record number < 0, go to last record in table...
Dim itbl as p
itbl = tbl.index_primary_put("")
tbl.fetch_last()

if tbl.is_record_locked() = .t. then
ui_msg_box("Error","Cannot edit record because it is locked by another user, or in another session.",UI_STOP_SYMBOL)
tbl.close()
end
end if
tbl.change_begin()
tbl.CUSTOMER_ID = convert_type(v_personnel,"Character")
tbl.TOOL_ISSUE_DATE = a5_eval_expression("=date()",local_variables())
tbl.Tool_issue_time = time("0h:0m:0s")
tbl.TOOL_EST_RETURN = a5_eval_expression("=date()",local_variables())
'tbl.SCAN_ID = a5_eval_expression("=Customer->Scan_Id",local_variables())
'tbl.UIC = a5_eval_expression("=Customer->Organization",local_variables())
tbl.rec_type="I"
tbl.change_end(.t.)
tbl.close()
tbl.refresh()

Re: Parent Table Restricted: Refetching Error

Stan and all....


Believe it or not, the problem self corrected itself. In the "Can Save" Event, I had the Assign browse properties as a seperate action (action scripting) and a different action script for doing the actual assigning of the records. When I combined the two different action scripts on the "Can Save", the problems with the refetching of the records dissappeared.

Lesson to learn....within 1 browse record event, only use in-line basic coding in one script....don't split them up.


I hope I'm right with that.

Thanks,

ryland

Re: Parent Table Restricted: Refetching Error

Ryland,

The message board will support formatted code. Your scripts will be much easier to understand with a bit of formatting. See this thread for how this can be easily achieved:

Re: Parent Table Restricted: Refetching Error

I'm glad you got things working. There is some "danger" to using converted action scripts without understanding the underlying xbasic.

tbl.close()
tbl.refresh()

There is no .refresh() method for a table pointer (tbl) and if there were it would be meaningless after the table pointer was closed.

Re: Parent Table Restricted: Refetching Error

Thanks Tom and Stan, and Tom you're right, I'll format my code next time. Ryland
