Combo box with data object

[TimStone]

The following code:


REDEFINE COMBOBOX oMake VAR cvMake ITEMS aMake ;
ON CHANGE ( aModel := SetVehModel( aModel, cvMake ), oModel:setItems( aModel ), oDvm:update( ), .T. );
ID 893 OF oDvm MESSAGE "Enter the make of the vehicle" UPDATE

REDEFINE COMBOBOX oModel VAR oUnt:vehmod ITEMS aModel ;
ID 442 OF oDvm MESSAGE "Select the proper model" UPDATE

now has a problem. The idea is when a make is selected in the first combobox, the array of models specific to that make is reset. That all works fine. However, the variable from the database, oUnt:vehmod, does not display. Essentially, browsing dow a file should display both the make and model in the dialog box, but only the make is shown. This is a relatively new behavior ( latest FWH update ). If I remove the oModel VAR it will show but then the aModel array does not get updated properly.

Your ideas would be appreciated.

Tim,

I suggest comparing the combobox classes from the two versions using a file compare utility. This should help you find the changes and thus narrow down the problem.

I use WinMerge (www.winmerge.org). It is freeware.

The error was unrelated to the combobox code. On the On Change, it had to do with the sequence the data was applied. When I changed the sequence of the steps in the process it worked. I'm not exactly sure why because logically the original order seemed correct, but it works now.

Tim,

OK, glad to hear you have solved it.
