Getting an error using SaveCSV2

[fdx12345]

I tried posting this question eariler but I believe my computer hickuped and the post was not established, least, I did not see it thus am reposting.

I have a table that I am saving to a file using StringUtils.SaveCSV2. The table can be empty at times before saving. When this occurs, the List variable (type List) will have zero data for a size of zero.

The error I am getting is: IndexOutOfBoundsException: Invalid index 0, size is 0.

How do I get around this? I do not want to add dummy data just so StringUtils.SaveCSV2 will work.

You can check List.Size before writing it with SaveCSV.

Check list size

I am checking list size which is showing getting zero. Since there is no data in the List, that is to be expected. The problem is I need to save the blank List because it will be re-loaded if the user closes the program and goes back into it later. If the user has deleted all of the entries and now wishes to add more, I do not want to show them the entries they thought they had deleted.

I have a work around involving coping the orginal file from the apk if the listsize is zero but there are other places in several routines were a listsize of zero is also a problem (an example of this would be loading using LoadTableFromCSV). I am hoping to find a more straight forward solution than a bounch of if, but and Ands statements.

If the table is empty then you can add the headers to the table and save the table with SaveCSV (instead of SaveCSV2).

Great!

I will try it.
