Why is e._currentRowDataNew.rec_id producing error - element not found?

Re: Why is e._currentRowDataNew.rec_id producing error - element not found?

Sarah: I had the _getData=true in the coding so that wasn't the issue in my situation. I was working from a 'view' vice a table, so I recreated the data I needed by bringing in the tables in the query section and abandoning the 'view'. After doing this, the issue was resolved. The difference between the 'view' and the tables, was the primary keys. The 'view' was missing the PKs. Whether it was the missing PKs or Alpha not liking the 'view', I'm not sure. But the issue is gone.

Ah! That does create an empty e._currentRowDataNew if the primary key is not specified. In that case, you need to specify the primary key in the Query (AlphaDAO) setup and include that field in the grid. There's a "Select Primary Key" button (it's "Select Primary Key(s)" if you used the view in the SQL Select Statement option) that will let you pick the primary key for the view.

Thanks for getting back to me Tom.

Re: Why is e._currentRowDataNew.rec_id producing error - element not found?

The only way I was able to reproduce the error mentioned in this thread was to NOT specify '_getData=true', ie NOT check the "Compute current row data". You MUST check "Compute current row data" (action javascript ) or pass in "_getData=true" as the final parameter for {grid.object}.ajaxCallback, otherwise the e._currentRowDataNew variable will not be created.

Action Javascript Setup:

If calling with straight JS:

{grid.object}.ajaxCallback('G',{grid.rowNumber},'handleClick','','_getData=true');

Here's my handleClick function. It displays a listing of all the properties available in e._currentRowDataNew, if present. Else, you get a message that it is not defined:

function handleClick as c (e as p)
	dim currentRowData as c = if(variable_exists(e._currentRowDataNew), stritran(js_escape(PROPERTIES_ENUM(e._currentRowDataNew)),"\n","<br>"),"e._currentRowDataNew is undefined.")
	dim js as c =<<%js%
var title = "Debug";
var html = "<div style=\"padding:10px;\">e._currentRowDataNew properties:<br/><div style=\"padding-left:15px;\">{currentRowData}</div></div>";
var buttons = "o";

A5.msgBox.show(title,html,buttons);
%js%
	handleClick = evaluate_string(js)
end function

If you ARE passing in "_getData=true" (aka, have checked "Compute current row data"), then there's something else at work here. If this is the case, please post your code---both the calling javascript and the xbasic---so others may inspect it for possible problems. Also, make sure you do not have errors elsewhere in your component.

Did you resolve this issue? I'm having the same problem.

Drew,

This happened so long ago that I don't remember what workaround I used to allow my project to move on. I got no replies other than those listed above.

Re: Why is e._currentRowDataNew.rec_id producing error - element not found?

I have a button in a read only grid that makes an ajax callback. My xbasic function tries to use e._currentRowDataNew.rec_id to store a value into a session var:

session.current_rec_id = e._currentRowDataNew.rec_id


I keep getting the error that this element (e._currentRowDataNew.rec_id) can not be found , but it IS there. To be honest, I have defined this field to be a link for opening up the detail part. Thought that might be a problem so I tested other character fields that are not special but get the same type of error. Only the name is changed. It's almost as if the "e._" construct is not working.

Any clues would be appreciated.

It doesn't look like it's there if you're getting errors. If it's reproducible in the debugging environment (working preview), run it through the debugger. If not, use PROPERTIES_ENUM(e._currentRowDataNew) - will produce a list of all the properties for e._currentRowDataNew. Dump it in a file or return it in some js = "console.log('" + js_escape(PROPERTIES_ENUM(e._currentRowDataNew) + "');"

Re: Why is e._currentRowDataNew.rec_id producing error - element not found?

is this rec_id the primary key?

in the definition of ajax callback, when you declare the xbasic declaration
the last line compute current row data or something that should be checked in order for the data to be available unless rec_id is primary key then it should be available,
