    <p>i'm working in a small function that should break a string in substrings making sure that none of words will be cutted.</p> <p>Let's get this use case: </p> <p><strong>"something is going wrong and i can't figure out what's the problem"</strong></p> <p>total characters: 63;</p> <p><strong>with a max chars length of 15 per line i would get this substr "something is go"</strong></p> <p><strong>as you can see it is cutting the word when i would like to get the entire word.</strong></p> <p>line[1]: something is //break the string on the last space bellow the max chars length;</p> <p>line[2]: going wrong .... //includes's the missing characters from the first line at the begining of the second line </p> <p>line[3]: .... //and so on until all the characters get looped.</p> <p>I come up with this solution which is driving me crazy. </p> <pre><code>function splitString(obj:Object):Array{ if (obj.hasOwnProperty("d_string")) { var texto:String = obj.d_string; var textoStr:Array = texto.split(""); var textoLen:Number = texto.length; trace("textoLen " + textoLen); var maxCharPerLine:Number; if (obj.hasOwnProperty("d_limit")){ maxCharPerLine = obj.d_limit; trace("maxCharPerLine" + maxCharPerLine); }else{ maxCharPerLine = 20; } var textLine:Array = []; var currentLine:Number = 1; var currentIndex:Number = 0; var cachedCharsForLine:Array = []; //all characters between the range var lastCachedCharsForLine:Array = []; //mirror of all characters stoping at the last space found var missingChars:Array = []; var canCleanData:Boolean = false; /*START LOOPING OVER THE STRING*/ for (var i:Number = 0; i&lt; textoLen; i++) { //&lt;block1&gt; if ( currentIndex == maxCharPerLine || i == textoLen -1 ){ canCleanData = true; } //&lt;block2&gt; 22 if ( currentIndex &lt;= maxCharPerLine ){ cachedCharsForLine.push(textoStr[i]); //trace(cachedCharsForLine); } trace(textoStr[i]); trace(textoStr[i] == " "); /*is the characters a space?*/ if (textoStr[i] == " ") { /*1. even after the condition above returns false*/ lastCachedCharsForLine = []; lastCachedCharsForLine = cachedCharsForLine; } /*as you can see from the output this value is being updated every iteration after the first space get found when it was suppose to be updated only if the a char of type &lt;space&gt; get found" */ trace("-----------------" + lastCachedCharsForLine) //&lt;block4&gt; if( currentIndex == maxCharPerLine || i == textoLen -1 ){ if (textoStr[i]==" " || textoStr[i+1]==" "){ trace("\n A"); //trace("@@@ " + lastCachedCharsForLine); textLine[currentLine] = lastCachedCharsForLine; trace("//" + textLine[currentLine]); } else{ trace("\n B"); //trace("@@@ " + lastCachedCharsForLine); textLine[currentLine] = lastCachedCharsForLine; trace("//" + textLine[currentLine]); } currentIndex = 0; currentLine ++; } //&lt;block5&gt; if (currentLine &gt; 1 &amp;&amp; canCleanData){ trace("DATA CLEANED"); canCleanData = false; cachedCharsForLine = []; lastCachedCharsForLine = []; } currentIndex ++; } return textLine; }else{ return textLine[0] = false; } } var texto:String = "Theres something going wrong and it's driving me crazy."; var output:Array = [] output = splitString({"d_string":texto,"d_limit":15}); for (var i:Number = 0; i&lt;output.length; i++){ trace(output[i] + "\n\n"); } </code></pre> <p>lastCachedCharsForLine's variable is being updated as you can see from this trace line.</p> <pre><code>trace("-----------------" + lastCachedCharsForLine) </code></pre> <p>even with the condition bellow returning false</p> <pre><code> if (textoStr[i] == " ") { /*1. even after the condition above returns false*/ lastCachedCharsForLine = []; lastCachedCharsForLine = cachedCharsForLine; } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
