re-arranging the tiles in sapui5

[Former Member]

Hi Experts,

I have created a SAPUI5 application for re-arranging the tiles on click of a button. The application was working fine and was able to re-arrange the tiles and model data was also getting updated.

Now, when i am trying to run the application again i am getting the error message as "Uncaught TypeError: Cannot read property 'style' of null".

Kindly assist me in fixing the error.

Hi Varun,

If I comment on below line in tileMove event , it works fine: JS Bin - Collaborative JavaScript Debugging

// var i = swap(obj1, initial, obj1, last);

What exactly are you trying to achieve with 'swap' function?

Hi Sai,

Using the swap function i am trying to update the model data.

For example, if I re-arrgange the tiles say Tile 0, Tile 1, Tile 2 to Tile 1, Tile 0, Tile 2 the corresponding model should get updated.

Thanks for your response . Looking forward for your response.

Thanks & Regards,

Varun,

Try adding a delayedCall to that function, it should work: JS Bin - Collaborative JavaScript Debugging
