Setting onDataChange via SolutionModel

Classic Servoy
1

Hi,

I have a new form that I have created in the SM. I created a combo box on that form and need to attach an onDataChange method to it. I can’t figure out the correct syntax and haven’t found an example on the forum.

I tried a few variations but couldn’t get anything to work. The method I am trying to attach is a global method called “item_type_filter”.

Here is one example of what I tried.

var	frmobject2 = myForm.newComboBox(globals.g_active_item_type,110,51,206,30) //combo box
         frmobject2.onDataChange = globals.item_type_filter();

Thanks!

Hi monetteboy,

Since the onDataChange property is of type JSField, I would try creating or getting such an object first and then attach it.
Like so:

var mtd = solutionModel.getGlobalMethod("item_type_filter");
frmobject2.onDataChange = mtd;

Hope this helps,

Thanks for the tip.

The form loads correctly now, but the method doesn’t fire.

I will play around with it some more but if you or anyone has any other thoughts that would be great!

Thanks again!

—UPDATE—

I found the method fires if I set the onFocusLost or the onFocusGained.

It does not fire if I set onDataChange or onAction.

Just wanted to post that I was able to get this working.

I had to change from using

var frmobject2 = myForm.newComboBox etc

to

var jsfield = myForm.newField(‘globals.g_active_item_type’,SM_DISPLAYTYPE.COMBOBOX,95,51,140,30)

then used

var mtd = solutionModel.getGlobalMethod(“item_type_filter”);
jsfield.onDataChange = mtd

I am not sure what the difference is between using the “newComboBox” and using “newField” with a type of Combobox, but at least it works.

Thanks for push in the right direction.

Glad to know it works!

But the difference between setComboBox and setField looks like a bug, IMHO.

You should post a bug report to the support system with a sample solution to help the Servoy engineer reproduce this inconsistency.

Yes, please create a case in our support system for this, with a small sample solution if possible

No problem I will try to get that done today.

Thanks!
