ember.js - How is selectedSection.savedItems computed property modified twice? -


i looping through saved items in component template , getting following error:

"assertion failed: modified selectedsection.saveditems twice on <wc-app@model:plan-section::ember615:goal> in single render. unreliable , slow in ember 1.x , no longer supported.

this code in component template:

{{#each selectedsection.saveditems |item index|}}

this saveditem computed property on plan section model:

saveditems: ember.computed('ordereditems.@each.isnew', function() {     let itemssaved = this.get('ordereditems').filter( (i) => !i.get('isnew'));     return itemssaved;   }),

when there 1 item or more problem not happen when there 0 items causes error.

how computed property modified twice?

transpose - Maple isnt executing function but prints function term -

im using maple im in worksheetmode tried using maple input , 2d input , want transpose matrix a: := `<|>`(`<,>`(1, .5, -2), `<,>`(.5, 9/4+b, 5+3*b), `<,>`(-2, 5+3*b, 18+9*b+4*a)); b:= transpose(a); when exectute sheet dont translated values, there same input. matrix looks same input matrix plus function term. you can see picture in following link: why arent functions executed? meanwhile b:=a^+ doing right way , transposed matrix. other functions return function body instead needed values... if using 2d input mode (the default) space you've got between transpose , bracketed (b) interpreted multiplcation. rid of such space. also, either load package @ start of document like, with(linearalgebra): before calling transpose command package, or call it's full name like, linearalgebra:-transpose(b);
