Re: Subelement Not Found

the date value could have been
update.expr4 = "null_value(),DATEREV)"
But I had a filter attached

Stans images show the same way I did it in operations

Re: Subelement Not Found

Hello Stan,

Your assumption is incorrect. The button is on a Menu form based on a dummy Table. The app is set t open to the Menu form. Thus there should not be anything open which contains data. When the button is pressed, it throws the error. Right now, I am on my laptop and using a backup of the app. The app opens, I click the button and this error pops up:

Script:Datapurge1 line:11
t.change_Begin()
Change already began

Well, isn't that interesting, especially since the first line of code in the script is parentform.commit(). Also, line 11 is a commented out line of code referring to a numerical field. That begs the question, What, exactly, does the error message mean and to what is it referring? Does it mean the error is on line 11? Does Alpha count commented out lines as well as empty or blank lines when it throws an error code? After some experimenting, I know that Alpha counts empty lines and commented out lines.

I edited my script so only character fields were evaluated. I closed the app and reopened it. Clicked the button and nothing happened except in the lower left corner of the screen appeared the words, Record 1. I clicked on the Control Panel tab and Alpha locked up. After several attempts of this procedure, each time Alpha locking up, I commented out the 4 lines of code referring to the loop, saved the script, closed and reopened the app. Clicking the button resulted in no error codes and in the lower left corner, the words Record 1 made a very brief appearance. I clicked the CP tab and no lockup. The CP opened.

OK, I opened the script and uncommented the 4 lines of loop code. After saving an exiting the app and reopening it, I clicked the button and the same thing happened, Record 1 appeared and did not disappear. (That's probably when Alpha locked up) I clicked the CP tab and had to close the program as it was frozen solid.

OK, so what's with the looping code? Why is it not throwing an error message? I have no clue but I'll keep working with it.

Re: Subelement Not Found

I figured out that the Change already began error message occurs no matter what was opened. Experimenting, I copied Stan's code and pasted it into my script, replacing all except the commit line. When I clicked the button, it threw an error because there is a line of code referring to a field that is not in this version of the app. I removed the line from the script and saved it. Clicked the button and the Change already began error appeared. The ONLY form and table that had been opened was the Menu form/Dummy table. The script editor was closed as well.

I ended up commenting out the 2 fields in the script which are not in this version of the app as well as one of 3 date fields along with the 4 lines of looping code. As long as those 4 lines are not in the script, it runs, even with the numerical and other 2 date fields intact. It ignores the numeric and date fields but it runs, nulling the character fields as directed.

SUMMARY

Alpha does not like the lines of looping code and will lock up if included. Why, I have no clue. However, I will try created an update operation without the genie and see what happens.

Re: Subelement Not Found

I was able to create the update as Stan suggested. I works beautifully from the operation tab. However, action scripting to run the operation from a button does not work. I chose Operation, Run a saved operation. Next, I chose the Summarytest table and that's where the problem lies. It will not allow any table to be accepted because the window stays open showing all the available tables. The script can be completed but the table selection window stays open and the default prompt appears to create an operation.

OK, enough, it's 2:21 and time for some zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz
