.Static method in multi thread program

658018Jun 10 2010 — edited Jun 11 2010
Dear Sir,

I'm using multi thread program so I want to know something of static methods how to use in multi threading

Example

public static int getSum (int a, int b){return a+b:}

When accessing this method at the same time by several thread How it is behavior ?

I'm meaning will it switch by another thread ?

and What is the simple this we need to think while using static method in multi threading program ?

Best regards
Kapila

it's the same model, only the view has changed (i think)

I don't know what element is triggering your code but I don't think this...

var trigger = $(this.triggeringElement);

var rowId = trigger.closest('tr').data('id');

...will get you what you want when you are in single record view mode

I tried this...

apex.region("theIG").widget().interactiveGrid("getViews", "grid").getActiveRecordId()

and it works if you are in edit mode...(using empno as my primary key column)

apex.region("theIG").widget().interactiveGrid("getViews", "grid").getActiveRecordId()

"7499"

but if you aren't in edit mode it returns nothing, so instead I tried this...

apex.region("theIG").widget().interactiveGrid("getViews", "grid").getSelectedRecords()

seeing as we are in single row view mode, it gives you the current visible row

but that's positional (same with getContextRecord()) so if someone moves a column then it may break your code, so you could get the position from...

apex.region("theIG").widget().interactiveGrid("getViews", "grid").getColumns()

there maybe something more appropriate, have a look at what is available...(change "theIG" to your static ID)

apex.region("theIG").widget().interactiveGrid("getViews", "grid")

you can then use the primary key column value to access the model as before (i think)

EDIT : and please change you username to something more recognisable than "3052157"

All your provided information were VERY helpful! All your assumptions where correct...

For other having the same problem:

- getActiveRecordId() delivers me only an ID if the record is in EDIT mode what I can't guarantee

- The user CAN switch the order of the columsn (allowed)

- Luckily getSelectedRecords([0]) provides the index (attribute 'index') in order to get the correct value in array of getColumns()

I check (again) my name but couldn't find/change it in profile.

Thanks a lot, very appreciated!
