extjs - Inserted image on panel's placeholder not rendering correctly -


i have weird problem regarding xtype: 'image' component added using insert() in panel's placeholder:

panel:

{   xtype: 'panel',   collapsed: true,   region: 'east',   collapsible: true,   split: true,   . . .    listeners: {     afterrender: function (panel) {       if (panel.placeholder) {         panel.placeholder.insert(1,           {             xtype: 'image',             src: 'myimage.png',             margin: '10 0'           }         );         panel.placeholder.settitle('');       }     }   } }

so problem is, icon added in placeholder not being displayed correctly, left being set @ 9px, when should 0:

afterrender

but after expanding said panel , collapsing again, image correctly displayed. have been cause? doing insert correctly?

note: margin config image being used extjs position element. however, left property of image being set @ 9px. have tried: margin: '10 0 10 0' or margin: '10 5' nor margin: '10 5 10 5' still image being set left: 9px makes me think l/r margins not being accounted for. when setting margin: 10, l/r margins being accounted.

edit: here's working fiddle reference, per @tejas1991 request.

try running fiddle. can notice, image of east panel not correctly positioned. now, try expanding panel , collapse again. voila!

well, seems have provide width of image in order correctly added placeholder.

panel.placeholder.insert(1, {   xtype: 'image',   src: 'myimage.png',   margin: '10 0',   width: 25 });

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
