Hello,

Simply putting a TSQLQuery in a Android form crashes.

I searched the lcl and sqldb directories but I couldn't find any place which says "Unknown property"

Any ideas where the exception could be or how to fix it?

It is probably a ARM issue, because using LCL-CustomDrawn-Win32 in x86 works fine.

I/lclapp ( 710): JNI_OnLoad called

It means the form file contains a FieldDefs property, which it does not find in the object itself.

To my knowledge, the FieldDefs property should not be streamed for a TSQLQuery.

Michael.

The message "unknown property" is located in the RTL and is used either by TypInfo or by the object reader. So it seems that you have a property in your LFM that's not named the same way as one of the published properties of TSQLQuery.

Ok, I found the issue. FPC 2.6.0 (or whatever I utilized to build my IDE, don't remember anymore) has:

  TSQLQuery = Class(TCustomSQLQuery)
  public
    property SchemaType;
  Published
    property MaxIndexesCount;
   // TDataset stuff
    property FieldDefs;

But in my branch this property is not published.

Ok, so I published the property in my branch and uploaded a new build to sourceforge:

http://sourceforge.net/projects/p-tools/files/Free%20Pascal%20for%20ARM/Windows/

And issue fixed.

thanks =)
